Abbey Motorists Centre expertise manufacture custom Stainless steel seamless pipe exhausts for any car, truck, bike, or anything with an engine. They can make custom stainless steel exhausts sound how you want and look how you want.

With the addition of high performance exhaust it will give your vehicle the rage and fidelity of what your vehicle is all about. A vehicle with a high performance stainless steel exhaust can be a lot of fun, or a whole lot of agony if you don't choose or get the right stainless steel exhausts, it may end up in the back yard, or in your garage just going to waste, and I'd hate to see that, so make sure that your starting with a good one at the first, save your money, and spend a lot of time looking to find just the exhaust, with the perfectly configured custom stainless steel exhaust system and you'll be a lot more satisfied with the outcome.

So what comes off the production line is a vehicle that is comparatively cheap to produce.

Add to that the thrifty but custom stainless steel exhaust system what more can you ask for? It has enough grunt and sporty appeal for the average family man going through his mid-life crisis and the factory makes a whole stuff load of money selling zillions of these things.

Stainless steel exhausts provided by Abbey Motorists Centre have character, and provide top class custom made stainless steel that will guarantee your money worth.

How To Buy And Grip A Chinese Cleaver

The proper cutting technique is one the most important things you will need to learn in order to cook like a professional. Different recipes use different cutting techniques for Stainless steel seamless pipe, so it’s important that you know when and how to use each one. Improper cutting can lead to food with an unexpected taste in it, or, worse, a meal that simply tastes terrible. Thus, Wok Fusion presents a guide for those of you who don’t know the difference between slicing and dicing.

It is important to consider two things before you start cutting. These are buying the right Chinese cleaver, and holding it with a proper grip. These two things can have a significant impact on the effectiveness of your cutting skills, so it’s recommended that you read more about these in the follow two sections.

Buying the Right Cleaver

In choosing the right Chinese cleaver, it’s important to decide what you are going to cut. Will it be a thick meat or some meat with bones? If so, it’s important that you use only use a heavy weight cleaver – a light or medium weight cleaver simply will not cut through thick objects without significant damage to the knife. On the other hand, if you only need a cleaver to do some light cutting – slicing, dicing, or peeling – a light weight cleaver is ideal due to its light weight size.

Of course, the medium weight cleaver is the most popular cleaver; combining the ability for light cutting with the power of the heavy cleavers, the medium weight cleaver offers the best of both worlds. Thus, for people learning how to cook, the medium weight cleaver is the best choice for them to buy.

Whatever cleaver you choose, it’s important to get a cleaver that is made from high-carbon Stainless steel seamless pipe. There is absolutely no alternative to a quality cleaver made from high-carbon stainless steel. These cleavers provide a comfortable feel, nice weight distribution, and are easy to clean and sharpen.

Other, inexpensive, cleavers are made from traditional carbon steel or, simply low quality stainless steel. These cleavers, however, have huge drawbacks: carbon steel cleavers are easy to sharpen but will rust and discolor acidic foods. As you can imagine, there is nothing worse than seeing rust and discoloration on your meals – simply put, it’s disgusting.

On the other hand, stainless steels cleavers are opposed to rust, but are extremely hard to sharpen. Again, it’s very difficult to make your meals properly with a dulled blade. High-carbon stainless steel cleavers eliminate BOTH of these problems and are clean, rust proof, and easy to sharpen. Everyone who regularly cooks will tell you the same thing; high-carbon stainless steel cleavers are the perfect cleavers. So remember – there is NO substitute for a good Chinese cleaver!

How to Grip a Cleaver

Now that you’ve got your Chinese cleaver, it’s important to learn how to hold it. This is a key idea as an improper grip can lead to accidents (both painful and not) and can also cause your hand to begin hurting due to stress. Thus, the idea is to use the cleaver in a way that feels comfortable, but also gives you as much power as possible. As such, there is only grip that chefs around the world suggest as the “proper” grip.

With your writing hand, hold the cleaver by its handle. Then, move the hand all the way up the cleaver’s handle. Move your thumb onto one side of the cleaver’s blade near the thickest part of the cleaver. Move your index finger to the side opposite of your thumb. With your other three fingers, grip the top part of the cleaver’s handle.

Thus, only three fingers of your hand should be holding Stainless steel pipe the handle, with the other two fingers on the actual cleaver blade body itself. While it may seem a little uncomfortable at first, it’s important that you practice using this grip as it allows the highest amount of control, but doesn’t end up tiring your arm.

25 Top Stainless Steel Gas Grills Compared

All too often consumers seeking a high end Stainless steel seamless pipe gas grill are won over by a manufacturer's reputation, the look of the grill or other factors such as recommendations from friends or family. Now, this is a fairly large investment, as appliances go, and consulting an expert in the field could help in making an informed decision.

A reliable gas grill specialist can help you evaluate the various features found in these high end grills and quide you to the best choice for the features you prefer. The simplest way to compare the manufacturers objectively, of course, is with a chart!

Some of the features on the chart are:

BTU Output: How many burners, and how many BTUs are standard? You'll need to do some math to determine the actual heat your food will receive. Ideally, you want to have over 95 BTU's per square inch of cooking surface. How will you know? Take your total BTU's and divide it by the primary cooking surface. So.... if your cooking surface is 660 square inches and the total BTU's are 104,000 then 104,000 BTU's divided by 660 square inches = 157 BTU's per square inch. That would be a winner!!!

Temperature Range: This is a very important characteristic if you like to do a variety of cooking. You'll be able to do everything from searing steaks to baking pizza with a large temperature range.

Burner material can consist of cast stainless steel, stainless steel sheet metal, cast iron, infra-red and even cast brass, which is used in commercial settings. Dual burners allow for indirect cooking and better heat control. Cast brass or cast stainless burners are your best bet. They will last longer and are more durable. Grease tends to burn through sheet metal easily.

Infra-Red Burners are an option for those who demand a well seared steak. Thinking of an infra-red cooking system? Temperatures on an infra-red cooking system can reach up to 1600 degrees on some grills. Infra-red cooking allows for quick, high temperatures, which cuts cooking time and helps seal in juices -- perfect for searing a steak. If blackened food or steaks are your taste preference – infra-red cooking is the way to go. If you plan on conventional cooking -- go with a hybrid that offers infra-red and standard burners. Tip – make sure you can convert infra-red burners back to standard for large parties.

Rotisserie backburners are a popular option. Used to cook large pieces of meat evenly, rotisseries use a lot less heat than normal grilling. BTU ranges generally range in the 13-15,000 category but the best grills offer 18-28,000 BTUs. Meats cooked using a rotisserie are generally juicier, self-basted and slow roasted. Tip - look for a model with a drip tray to make cleanup easier. Be sure to compare available rotisserie space, especially if you want to roast a turkey or two.

A Triple Gourmet Grill allows you to use gas, infra-red AND charcoal cooking! How versatile can you get!!

An adjustable smoker box is perfect for those who enjoy the added flavor of hickory, mesquite or other wood to your meats. It makes smoking easy. Adjustable vents allow you to control the amount of smoke flavor to provide just the right taste.

Warranty is one of the most important features to consider. Only the best grills offer a warranty against a condition called burn through which affects the burners.

Does the grill you are considering offer a countertop model? These types of gas Stainless steel seamless pipe can be dropped into an outdoor kitchen which can be customized with your choice of tile, stucco or other solid surfaces, doors, drawers and other accessories like refrigerators or sinks.

Cooking Grids: Stainless steel cooking surfaces won't rust or chip. Porcelain cooking surfaces tend to chip and could flake off into food. No N.S.F. (National Sanitation Federation) affiliates use porcelain cooking grids.

Cooking Grid Size: How many people do you regularly feed? The size of your crowd will determine how big your grill should be. Tip – make sure you can convert infra-red burners back to standard for large parties.

Inner Liner: This accessory radiates heat more evenly to grill, directs dripping to tray and separates the valve and manifold from combustion chamber. This will prolong the life of your burners and reduce the chances of a grease fire. The grill hood covers the cooking surface and assists in trapping the heated air inside. Look for a double insulated wall hood. If you're buying a stainless steel model, with a double insulated wall hood, it won't turn a brown or blue hue. It will keep it's shine.

Stainless Steel Flavor Grids: This heat distribution system should be stainless steel for long life and durability. Flavor grids reflect all the heat up toward the grilling surface and vaporizes drippings. You can add wood chips and other flavor enhancers to your flavor grids to add some zest to your choice of meat.

Fuel Conversion: Will your grill easily convert from natural gas to propane if you want to move it from the back yard to the street for a block party?

Side burners provide versatility giving you separate controls for each burner. Side burners offer you additional cooking options and come with single or double burners. You can fry up some french fries or treat the team to sweet corn. The BTUs range from 12-17,000, but be sure to look for cast brass or cast Stainless steel pipe burners.

More Great Options:

A power/wok burner will give you even more cooking diversity. Saute onions or boil lobsters! Brown butter or deep fry a turkey! Having a party? A power burner can accommodate a 26" wok! With a range of 3,000 - 60,000 Btu's, the power burner is a definite advantage for any cook!

A full sear plate or briquette tray (which can also be filled with lava rocks or wood chips) under the cooking surface protects burners and allows for drippings to smolder which gives foods more flavor. Look for a model that will quickly flash the drippings eliminating flare-ups.

Adding a warming rack will keep food warm and away from direct heat and also give you extra cooking space.

Add a griddle to your side burner and enjoy breakfast alfresco!

Stainless Steel Fabricator

Stainless steel seamless pipe fabrication refers to the shaping and bending techniques of stainless sheet metal processing. Stainless steel can be given all different types of sections and complex hollow shapes. The equipment which is used for these processes can range from sophisticated power tools to simple hand held tools.

When starting out on a stainless fabrication job, it generally begins with a preliminary action such as perforating, slitting or cutting, with tools that perform some type of shearing action. These may be power operated machines such as bench shears for heavy gauge material, or simple hand held scissor like cutting tools for thin lightweight stainless steel materials.

There are different types of power driven shearing machines, and these machines will comprise of a moveable blade and a fixed blade.

Punching is another process carried out by the use of a punching machine and it is used to punch or pierce a hole in the metal workpiece.

Shaping is a sheet metal process, and a wide range of shaping operations known as bending or folding are done on presses. Other operations carried out on presses can include;

o Crimping and beading

o Grooving and seaming

o Stamping

Most of these processes are used to stiffen and shape the stainless steel pipe sheet, and these machines may also be used for creating tubular and circular shapes and other numerous purposes. Sections and angles may be formed by folding or bending.

Coiling is another process used to produce a coiled edge on a sheet metal component. Coiling helps to provide a suitable edge and increase the strength of the article. Cylindrical and other circular or curved shapes such as tubes are produced on a roll-forming machine.

There are many different techniques used in the fabrication of stainless steel and other sheet metal processes, and some of these are:

o Embossing

o Cupping

o Deep Drawing

o Marforming

o Spinning

o Flow forming

o Milling & Turning

Most of these techniques and processes are now produced with the aid of computer controlled machinery due to the rapid advance in todays technology. Most of the above processes can be easily carried out on many different types of metal such as mild Stainless steel seamless pipe and aluminium etc.

Stainless Steel Refrigerators

One of the most commonly Stainless steel seamless pipe remodeled and refurnished rooms in most homes these days is undoubtedly the kitchen. This is because it's a great way to increase the amount of the productivity and space that one may need to, or desire to, achieve while adding a very modern and stylishly sleek look to the house.

It is definitely a room that is meant to remain unique to the rest of the house. For this reason, as well as many others, a increasingly popular look is that of stainless steel. While this rings true for most kitchen appliances, it is especially true of the refrigerator.

Stainless appliances are taking over more and more kitchens everyday. However, while many individuals are investing in a variety of stainless products that include the oven, microwave, or dishwasher, there is no question that the monstrous refrigerator is the most common and immediate investment to be turned stainless by many.

The fact that they are so massive and have the potential to be such an eyesore plays a rather large role in the growth in popularity of stainless steel pipe. It's the first thing that anyone will see walking into a kitchen, making it the most important appliance to have looking sleek and stylish.

Part of what makes these refrigerators so popular is the clean look that they provide. After all it's all in the name: stainless steel. They make for a very elegant and clean look that is remarkably easy to maintain, which in turn makes keeping the kitchen tidy a much easier task. With a kitchen that is armed with one of these appliances, an individual will never have to worry about fingerprints, smudges, or even smears again.

Let's be honest, when it comes down to it, a kitchen appliance needs more than style. While having an inviting and well furnished kitchen is something to be proud of, without practicality it's all for nothing. Many of these fridges have great features to go along with the elegant style.

For example they may have a plethora of interior and exterior features including, temperature adjustment for the fridge as well as deli drawers, humidity adjustment for drawers, a freezer and ice and water machine, and even child locks.

There's no doubt that these refrigerators are quickly becoming the staple for the modern kitchen. For low prices on high quality Stainless steel seamless pipe, try shopping at your local appliance store.

Bearings Fit For Cuisine

Bearings play an essential role in food processing from bakeries to seafood canneries to bottling plants. Like any component in a high-speed, high-volume production line, their unexpected failure or unscheduled maintenance can be devastating. To reduce the risks and avoid painful consequences, engineers must observe housing and insert materials as well as the type of Stainless steel pipe bearing itself. What follows is a review of these important factors and practical advice for times when bearings are in contact with food.

In the house

When specifying bearings, designers must often choose housing and insert materials. Common housings include thermoplastic composites, nickel-plated cast iron, stainless steel, and polymers. In most cases, the application environment — daily exposure to high-pressure washdowns, humidity, caustics, and antibacterial solutions — dictates which housing material to use.

Sometimes, for example, acids, cooking fats, and other chemicals used in food and beverage processing may come into contact with the bearings. This can be avoided by employing composite or thermoplastic-housed units. Another option is cast stainless steel (usually made of AISI 300), which withstands strong chlorine and hydrogen peroxide concentrations.

Other materials such as high-strength, cast iron work best for red meat, pork, and poultry processing. Nickel-plated, cast-iron housings, on the other hand, are easier to clean and rid of debris and bacteria because of their smooth surface finish and solid-base mountings. The most common plating — CNC (copper, nickel, chrome) — durably resists corrosion and appears bright and shiny. Proper CNC sanitation prevents E. coli, salmonella, and staphylococcus aureus growth. Many of today's bearing housings also contain antimicrobial coatings to further thwart bacterial and fungal growth.

In addition, polymer housing offers excellent corrosion resistance, a chip-free exterior (as opposed to plated housings), and economical prices compared to stainless steel. But unlike stainless steel, polymer materials do not provide equal load strength.

Insert here

Bearing inserts are made variously from stainless steel, thin dense chrome (TDC), and zinc. Stainless-steel inserts — although expensive — are regularly found in the food industry as they offer high-corrosion resistance. Generally, their outer and inner rings and balls consist of AISI 440C stainless steel. TDC coatings offer an alternative to this as they resist corrosion up to 15 times more than normal 52100 bearing-quality steel and provide greater surface hardness.

Zinc-coated inserts also guard against corrosion, come in most sizes, and cost less than stainless steel and TDC. However, plane bearings are needed during severe operating conditions where rolling-element inserts are not allowed. They usually install into any mounted housing that accepts rolling-element bearings. In addition, polymer and Stainless steel seamless pipe combinations comply with requirements for a bushing-type design.

Lube stop

Normally, an FDA/USDA-approved grease (classified as H1 for incidental food contact) lubricates food-grade bearings. H1 lubricants are odor-free, tasteless, washout resistant, and harm-free to food. Whenever possible, bearings should be relubricated to replenish the old grease supply and purge contamination.

When relubrication is not possible, however, polymer-solid lubricants can be employed. During bearing operation, they release a small amount of oil to coat rolling elements and raceways, resist washout, and reach hard-to-maintain areas. On the downside, they handle speed and environmental limitations poorly.

Daily specials

Over the last 10 years, many special bearings (both mounted and unmounted) were created to improve food processing. Concerns influencing these designs include:

Wet environments — due to water and equipment washdown

Harsh chemicals — sanitation and cleaning requirements

Excessive heat — baking and frying

Excessive cold — freezer applications

In any of these environments, bearings must be shielded from corrosion. This is achieved through corrosion-resistant platings, coatings on metal surfaces, or materials that inherently offer corrosion resistance, such as stainless steel or polymers. Stainless steel offers the best corrosion resistance in the aforementioned environments and is therefore preferred in meat-processing plants for equipment and bearings.

Plated bearings, on the other hand, best suit wet areas with limited chemical washdown. Their lubricants must be USDA-approved food grade (H1 or H2) only. Many high-end, food-grade greases lubricate as effectively as conventional petroleum greases and contain additional qualities such as low-temperature operation and washout resistance.

Basic styles

Mounted bearings typically come in three basic housing-material combinations: plated or coated cast iron; polymers or composites; and stamped, cast, or machined stainless steel. Insert bearings are available in several corrosion-resistant platings or coatings: Zinc chromates, TDC, and black-oxide coatings are most prevalent.

Unmounted bearings are made of stainless steel and other highly corrosion-resistant materials such as high nitrogen corrosion-resistant steel (HNCR). HNCR resists corrosion better than any stainless steel while maintaining a material hardness similar to average bearing steel. HNCR materials therefore eliminate the capacity reduction inherent in stainless-steel bearings.

High-temperature bearings generally incorporate a graphite separator that lubricates bearings at temperatures above 600° F — something conventional lubricants such as grease and oil cannot do effectively. These mounted bearings increase life and lower maintenance costs in difficult baking, frying, and drying applications.

Plane bearings consist of a bushing-type design where two surfaces mate to each other without a ball or roller. They are available in several housing styles and bearing-material combinations for lubricant-free operation (sometimes required for sanitation) and easy cleaning. Unlike conventional ball bearings, they can be completely disassembled, cleaned, and reinstalled for safe use in and above the product zone — where conventional rolling-element bearings are unapproved. However, this style limits both speed and load compared to conventional ball bearings. Plane bearings are made of stainless steel or polymers for various operating requirements and temperature ranges.

Other options

Seals are one of the more common options used with bearings. They are intended to keep lubricants in and contaminants out and are an important consideration in food-processing applications. They vary from conventional single-lip rubber types to double-lip designs and are often coupled with metal fingers fitted outboard for added protection. For high-temperature applications, various silicone materials are available and advised.

End closures added to housed units further protect the inserts, prolong bearing life, and act as safety measures against rotating parts. There are open-type units, which allow shafts to extend through and closed types for stub shafts. Most often, covers are made from either stainless steel or composites.

Other options for a complete food-grade bearing assembly include stainless steel or nylon cages,Stainless steel seamless pipe setscrews, stainless steel or corrosion-resistant coated fingers, corrosion-resistant collars, and Stainless steel grease fittings. Survivability is key for the bearing, as well as the load.

Stainless Steel Chimney Liner

You still aren't over the shock of the esitimate your chimney sweep left you for what he says is needed to use your chimney safely. He told you that you need to install a stainless steel chimney liner in your existing masonry chimney. You have no idea what a Stainless steel seamless pipe chimney liner is. Most of all you have no idea why the sweep wants so much money to do the job.

Chimney Liner Metal Alloys

You found your way to this site, so you must be interested in doing the job yourself. So lets discuss some options you have and the types of stainless steel chimney liner that are out there.

First thing you should be aware of is that most manufacturers won't honor a warranty for a stainless steell chimney pipe installation if a non professional does the work. However, Royal Chimney Supply, the manufacturer of Flex King chimney liners will honor the warranty if you do the job yourself.

You can choose to use either a rigid stainless steel chimney liner or flexible pipe. Flexible pipe should be used if your chimney is less than perfectly straight with no joggs or offsets. If you have a nice straight chimney you most definately should use rigid chimney pipe.

Compare Chimney Liner Brands

Rigid stainless steel chimney liner is the best product available to line a chimney. It's thick, and cleans the best. It's the most durable and will never rip if you clean it agressively. Light flexible chimney liners need to be cleaned with a type of plastic chimney brush because they are so thin.

There are different types of thicker more durable flexible liners available. Flex King Pro is a double wall, smooth interior liner. It cleans much better than standard Flex King liners and is more durable.

Heavy Flexible liners are very thick and durable. The only problem with them is that they are very heavy. A homeowner may have some trouble when installing a heavy flex stainless steel chimney liner.

More info about Stainless Steel Chimney Liner

If you are going to purchase a light flex stainless steel chimney liner you should buy one that is made from 316TI stainless steel. A lot of lesser quality liners are made from 316L. The TI stands for titanium. The addition of titanium gives the liner the ability to withstand less than perfect chimney conditions

Should I insulate my liner?

You should definately insulate your liner if you have the room. Why? With a wood or coal stove you will lose a lot of heat up the chimney. When hot flue temperatures meet with cold temperatures it will create condensation. When flue gases meet with condensation the result is creosote. By reducing the formation of creosote you will lengthen the life of your chimney liner. Keeping your chimney liner warm will also keep the draft consistent and will improve the performance of your stove.

What is a Rigid Chimney Liner?

Most rigid chimney liner sections are made of nonmagnetic, series 304 or series 316 Stainless steel pipe. Unlike the flexible stainless steel liner, rigid pipe comes in sections and is usually round in shape and one to four feet long and five to ten inches or more in diameter. The most common wall thickness is 24-guage (0.024 in.) or 22-guage (0.029 in.) stainless steel.

The seam running down the length of each liner sections is factory sealed. Individual liner sections are joined together with the crimped, male end facing down. Stainless steel pop rivets and stainless steel screws secure the joints.

Pop rivets are recommended by most manufacturers since screws may work themselves loose from the expansion and contraction of the liner. Usually rigid relining jobs are supported at the bottom of the chimney or at the thimble area.

Stainless steel tee sections are used at the thimble and clean out areas. Rigid stainless steel liners can expand several inches during heating. To accommodate for this expansion the liner moves up and down in a sleeve at the top of the chimney.

A storm collar over the sleeve prevents moisture from entering the chimney along the outside of the liner. The area around the sleeve at the top of the chimney is sealed with either a stainless steel plate or a concrete pad.

The opposite of rigid chimney liner, flexible chimney liner

The use of rain caps are recommended for use on chimneys with stainless steel liners. It can be very important to have the most efficient venting possible.

A smooth walled rigid liner offers the most efficient venting due to the decreased turbulence. You can shape it to take full advantage of every cubic inch and offer maximum draft. It can be shaped into rectangular, square or oval.

Stainless steel resists corrosion, maintains it's strength at high temperatures and is easily maintained. For these reasons, it is used widely in items such as automotives, home and food processing products, as well as medical and health equipment. The most common types are: 304; 316; 316Ti; 316L; 29-4C.

316TI Stainless Steel

316TI is a stainless steel alloy with a small amount of titanium added. It's make-up allows it to resist acids and the stresses of hot and cold cycles. It can be used with solid fuels (wood, coal and pellet), gas and oil. It can withstand temperatures up to 2100 degrees.

316L Stainless Steel

316L chimney liner metal is commonly found in some thicker flexible chimney liners as well as in rigid chimney liners. The titanium is left out because of the added thickness of liners made from 316L stainless steel. 316L stainless steel is acceptable for use with coal, wood, gas or oil systems.

304L Stainless Steel

304L is best for chimneys venting a wood burning appliance. This alloy is commonly found in rigid chimney liner.

The most commonly specified austenitic (chromium-nickel-stainless class), it accounts for more than half of the stainless steel produced in the world. This grade withstands ordinary corrosion in architecture, is durable in typical food processing environments and resists most chemicals.

Al 29-4C Stainless Steel

This chimney liner metal alloy is used most often when relining a masonry chimney or clay lined chimney that will vent a modern high efficiency gas or oil furnace.

It is an alloy of stainless steel pipe that is highly resistant to corrosion. It is used for relining flues where flue gases may contain highly corrosive elements. Being that most of the heat generated by such a high efficiency appliance goes into the home, the flue gas temperatures tend to be relatively low.

Low flue gas temperature keeps moisture in the flue gases from evaporating and being eliminated up the flue. The combination of moisture in the flue gas along with other chemicals that may be inducted into the flue from the surrounding environment, such as those from chemical cleaners and laundry supplies, can contribute to a very corrosive flue gas composition.AL29-4C is made to resist such corrosive environments over a long period of time.

Process Puzzler: Soothe A Skittish Supervisor

THIS MONTH’S PUZZLER

We use a carbon-steel spiral-tube heat exchanger as a condenser in our spray tower. Operating conditions normally are 100 psig at about 150°F. Treated chilled water at 45°F runs in the tube side. The shell side handles metal chlorides, e.g., FeCl2, VCl4 and TiCl4. These chlorides condense to form liquids and evaporate to form gases Stainless steel pipe. Severe corrosion from chlorine and erosion was the reason why the spiral heat exchanger was chosen over a shell- and-tube one. The chlorine is usually dry but, occasionally, spikes of water upstream of the exchangers cause corrosion. One of our engineers is pushing the idea of cladding Type 304L stainless steel with a high nickel alloy. Coupon tests suggest this will improve service life. One concern is how bending the tube will affect cladding. How can we assure our nervous operations manager that this cladding will work? Do you have any other ideas? Keep in mind replacing the heat exchangers with another style will require a major change in piping around the units.

REPLACE THE EXCHANGER

Try looking at a hybrid heat exchanger that incorporates the strengths of both plate-and-frame and shell-and-tube exchangers without their weaknesses. It is a good compromise between cost and performance. My experience is only as a happy customer of an exchanger manufactured in France. Its design tends to provide the best lifecycle cost choice for our circumstances.

LOOK AT TANTALUM LINING

I think that you have not considered all of the options available. Cladding is a risky option. Maybe replacing the tubing with duplex steel would be a better option. Another idea would be to seek a consultant. There is a manufacturer in Germany that makes “tantalined” equipment for the fabrication of spiral exchangers with lined carbon steel pipe. This last item might be your best choice.

WATCH THERMAL EXPANSION

We have used nickel-plated copper Stainless steel seamless pipe tubing for similar heat-transfer applications. The plating can be applied after the tubing is bent, but you’ll need to be careful about the amount of expansion you get from temperature variation.

CONDUCT THOROUGH TESTING

Some years ago an engineer at our plant in Grimsby, U.K., looked at tantalum cladding for our chlorinators. These are large brick-lined reactors. Inside, chlorine comes in contact with carbon monoxide from burning coke; the chlorine reacts with ore to chlorinate it, producing titanium tetrachloride, TiCl4. Trace water and hydrogen chloride (HCl) in recycled chlorine is a continual problem. Unfortunately, the brick and carbon steel shell of the chlorinators is quickly attacked at the moisture penetration zone — where the water and HCl condense. These chlorinators are water-cooled by falling-film heat transfer, making it difficult to detect a breakthrough of the shell. Such a breakthrough posed a significant environmental risk.

The engineer thought tantalum, the only material not susceptible to attack by wet chlorides, would work. He was looking into coupons to test in the next chlorinator turnaround. These coupons included welds and other features.

With the heat exchangers, the combination of welds and bends offer a challenge for coupons. I suggest installing a coupon that includes welds and a distressed plate, not unlike the forming process for an elbow. Test in a large vessel, if possible, to avoid affecting the chlorination process. If the coupon survives, your cladding idea may succeed. The next test involves checking the manufacturing process. A very good test for identifying cracks in metal tubes is an acid dye-penetration test. It’s a destructive test that will reveal voids in the interstitial areas between crystals in nickel alloys and similar metals that ultrasonic means won’t identify. Use this method to validate the manufacturing process.

It would be really easy to grow shy about this application. When we considered cladding of our heating coils, which operated at about 1,000°C, we opted out. We felt that it was too risky and chose to go with high nickel alloy coils instead.

MARCH’S PUZZLER

Management wants to boost production from our batch polymer process by changing the operating procedure. Now, a portion of the acrylic monomer goes in with the bulk of the solvent and other ingredients. Then, monomer is slowly added until the reactor level rises to about 55%. Instead, management wants to increase the maximum level to about 65% and raise the final concentration of the polymer about 2%. The reaction is very exothermic; a chilled-water baffled jacket provides cooling Stainless steel seamless pipe. At the top of the reactor a horizontal shell-and-tube condenser that uses cooling tower water captures evaporated solvent. Agitation consists of a single axial impeller and the tank has reduced baffles to account for viscosity above 5,000 cP. To meet the production goal, it’s been proposed that we add all of the monomer at once; bench-scale tests have shown that this could work but our current approach seems safer. Management likes the plan and wants to put into practice immediately. Our production engineer is a little nervous — should he be concerned? How should we approach this problem? Are any process changes necessary? What do you think?

While at first glance deburring & finishing Stainless steel pipe and aluminum railings may seem somewhat a niche market it should be noted that with the correct Dynabrade tools, grinding, sanding and polishing products almost any weld shop can take on this type of work.

It is hard to put a number on how many steel fabricators, welding shops, artists garages, etc. I have been called into because a nervous owner, foreman or project manager took on railing jobs that were above their expertise. Most thought they were going to lose their shirt once they got to the metal finishing stages on somewhat temperamental stainless or aluminum.

The best advice I can give anyone who wants to Brush Finish Stainless Steel or Aluminum Railings in a professional manner is set up your shop and your polisher with the necessary Dynabrade tools and Abrasives. If you are willing to allocate some of your time and hard earned money as an investment in yourself and your company the quality stainless or aluminum railings you produce will come back to you financially many times over. The most common abrasives questions I get asked for these metal finishes are some of the easiest to answer. That’s not to say I haven’t seen some interesting challenges over the years. I have been in over 1,000 shops that work on all types of metals and woods.

A consistent finish on stainless or aluminum railings steel fabricators want to achieve is a brush, satin or #3 finish or #4 finish. Most steel fabricators order the Stainless steel seamless pipe or aluminum pre-finished to this specification and only need to bring the areas they have welded back to a nice clean satin finish which will match the rest of the metal railings original finish.

I like to see anyone who is serious about working with metals such as stainless or aluminum own at least two Dynabrade tools for their shop. The first is a Dynabrade Dynafile. There are many variations of the Dynafile which Dynabrade Manufactures. They are as follows: The Original Dynafile model 14000, the dynafile II model 40320, and the Electric Dynafile model 40590. Either one of these Dynafiles will do the job.

I prefer the Dynafile II series air or electric. They seem to be the most versatile. You can position the rotating sanding belt head in many different positions depending on the angle of your work piece. The Electric dynafile II and the Air Dynafile II also accept over 20 interchangeable contact arms which will hold sanding belts and surface conditioning belts 1/8” to ?” in width.

The Dynafile’s primary function is to grind and polish hard to reach areas on a metal work piece. Some examples of this are the corners or where the welds join together two or more parts. The second Dynabrade Tool I find to be a necessity from Dynabrade is from the Dynastraight Family. These tools include: The Dynastraight model 13204 .7 hp 3,400 RPM or the Dynastraight model 13505 1 hp 3,400 RPM.

I like these models because they are rated at the proper RPM and have male 5/8-11 threaded wheel arbors which are standard and allow for many different abrasives to be mounted and used on them. If you want to use a dynabrade inflatable rubber drum with sanding belts or surface conditioning belts on it the Dynabrade Pneumatic Wheel Stainless steel pipe part number is 94472. I also recommend a combination of unmounted 6x1x5/8 flap wheels in assorted grits for either Dynastraight to help bring the Railings back up to the 3 finish or 4 finish.

The Worthy of Stainless Steel

Over the past century, Stainless steel pipe has arisen as the first metal of choice for many applications. You will find stainless steel at the top of skyscrapers, in your sink and in your hands as you use tools and various other objects. But is stainless steel really all that great? How does it compare to other metals? Here is some basic information about stainless steel to examine its worth and popularity compared to other metals.

What is stainless steel?

Stainless steel may be defined as an alloy of iron and carbon with a chromium content from 10.5 - 11.5%. Metallurgists began working to form stainless steel in the 19th century, but it was not until the early 20th century that stainless steel became mass-produced and widely used. The chromium content is the secret to the stain-resisting properties. When chromium comes into contact with oxygen it creates a film called chromium oxide that encases the steel and provides a sort of barrier against corrosion. Whenever the layer of chromium oxide is breached, it will "self-heal" and continue to create another film as the exposed chromium interacts with oxygen.

Can stainless steel rust?

Yes. It is important to note that while stainless steel does strongly resist any form of corrosion, it is not completely immune to corrosion and rust. While only gold and platinum are entirely impervious to corrosion, stainless steel is the most economical choice for endless applications. The best way to prevent stainless steel from rust and corrosion is to keep it clean. When kept clean, this steel can come into contact and withstand diverse environments and chemicals. Abrasive materials can break down the ability of stainless steel to resist corrosion. Whenever cleaning an item made of stainless steel, refrain from using abrasive materials or brushes. Soft cloths and various kinds of soap are recommended as long as they do not contain chloride.

Stainless Steel Grades

The most common grades are 304 (18% chromium, 8% nickel) and 316 (16% chromium, 10% nickel, and 2% molybdenum. Grade 304 is the most versatile and widely used stainless steel. Originally it was called 18-8 because of its chromium and nickel content. Grade 316 has superior corrosion resistance and is often referred to as the "marine grade stainless steel" and is used in food and laboratory equipment, medical devices, threaded fasteners, and marine applications. Grade 302 has given way to 304 due to availability and price but is still found in items such as washers and springs.

How has it been used?

Stainless steel is perhaps one of the most broadly applied metals in the world today. One will find Stainless steel seamless pipe in everything from buildings, to wrist watches, from monuments to skate blades. In 1930 the Chrysler Building in New York City was erected and capped with 302 grade stainless steel. A recent inspection of this building reveals the durability of stainless steel and its resistance to the elements as no corrosion or loss of thickness was found. The St. Louis Arch is the largest man-made monument in the United States. The concrete arch is covered with nine hundred tons of stainless steel from top to bottom. [3] Ever since 1965 when the arch was completed, cleaning is the only maintenance the 603 ft. monument has needed.

While the average person may not always have contact with these two monumental structures, most people interact with stainless steel products every day. Many household appliances from cabinets to sinks to dishwashers consist of stainless steel. This metal is chosen often in the kitchen because of its durability and sharp aesthetic appeal with only the occasional cleaning necessary to maintain its look.

Stainless steel is not merely good for aesthetics, but many tools are now made from stainless steel. Because of the superior strength and durability of the metal, homeowners and businesses have chosen to incorporate stainless steel tools. One business has even commented, "Replacing carbon steel tools with stainless steel tools eliminates this risk and should be considered a standard operating procedure for any modern facility." High-risk jobs require reliable tools that won't corrode or break during use. No one likes to find a tool rusted when it is needed for a particular job in the house, and homeowners can't afford to continually buy replacement tools.

Hardware made of stainless steel benefits the user with all the above qualities of stainless steel. Today you can find stainless steel hardware from basic nuts, bolts, screws and chain. You'll also find highly specialized and complex fittings and hardware used for rigging and marine applications.

What about other metals?

One of the most common elements in the entire universe is iron. Because of its abundance and relatively easy accessibility, iron has been a popular metal for tools and various other objects for several millennia. Cast iron is used to make bicycles, machines and hardware. Yet, iron metals may break and are easily susceptible to rust. Rusting takes place whenever iron materials come into contact with oxygen and water (moisture). Because of this liability, rusted iron loses integrity and can become dangerous in critical situations.

Nickel is a metal commonly used as an alloy. Even the nickel as currency is 75% copper. Nickel is commonly used as a metal in cast iron or even stainless steel. However, nickel is seldom used as a metal unto itself.

As was stated earlier, titanium stands out as one of the only elements in nature that is of itself completely rust resistant. Titanium is uniquely light, durable and dent resistant. Yet, with all of these qualities, titanium needs to be refined and is not normally produced in vast amounts. This results in high prices. Normally, titanium will be included in an alloy such as stainless steel or aluminum. Sometimes it will show up in watches or even wedding rings, but again, only in small amounts because of supply and cost.

Zinc is another metal, like nickel, that is better applied in alloys. Often times it is used to coat other metals for corrosion resistance. Architects increasingly employ this material for its UV resistance, natural tones and corrosion resistance.

One of the most common and cheapest metals is aluminum. When in its pure form, this metal is relatively weak and impressionable, but when united to other metals in alloys it becomes much stronger. If aluminum is used for critical applications, it appears as an alloy. Because this material is so light and cheap, most large objects (cars, planes) that require a large metal structure incorporate aluminum as an alloy.

These metals (and a few others) each have their own particular benefits. Rarely will any of these materials constitute a single object by themselves. Normally, objects are a composition or alloy of several of these metals. Even though stainless steel is always composed of iron, carbon and chromium, it may have these other metals as well. All things considered, it should be noted that stainless steel as such is a superior metal in a lot of ways. It is extremely strong, stain resistant, and can be fashioned to fit many different applications.

While titanium and gold may be stronger and more durable, their cost makes them an impractical material for objects when stainless steel pipe can accomplish the job with extreme efficiency and lower cost. The growing popularity of stainless steel over the past century has not happened by accident. If you are considering purchasing a tool, appliance or building a national monument, you should employ the superior qualities of stainless steel. Without a doubt, stainless steel is worth the extra cost as it returns years of durable service in whatever form it is used.

Design and Uses of Perforated Stainless Steel

The perforating of Stainless steel pipe is a process made popular due to the many desirable and durable properties of this alloy. Stainless steel is essentially a steel alloy with a minimum of 10% chromium content by mass. Stainless steel (It stains less) is named just that; because it does not stain, corrode, or rust as easily as ordinary carbon or mild steel. It can also be called corrosion-resistant steel. One common misconception however is that it is stain proof, this is an exaggeration of its metallurgic properties.

Stainless steel is available in various grades, approximately one hundred fifty total, yet only fifteen of these grades are commonly used. The individual grades of stainless steel are divided into groups or series based on their specific composition (100, 200, 300, 400, 500, and 600 series). The stainless steel is also classified according to its aesthetic finish which is applied after the material has been milled to size and thickness. Some examples of popular finishes are matte, satin, brushed, reflective, mirror, and a simple coarse abrasive finish.

Perforated stainless steel is typically produced using two popular production methods. The first, and more popular, is an all-across perforating press which perforates a row or pattern of holes across the material. The material is fed through the press in a precisely controlled fashion to produce a repetitive pattern. The finished material is automatically sheared or cut into specific lengths to create individual sheets.

The perforated stainless material can also be left intact as a single length of material and wrapped into a coil. A sectional or two axis perforating press is another method of producing a perforated Stainless steel seamless pipe sheet. In this case, the machinery moves the raw material beneath a stationary punching head in various patterns using two horizontal axes to guide the sheet. The end result is a pattern of holes based on the machine program and the desired output. This method is popular for unusual, non-repetitive patterns. It is also used when the raw material is too large or too wide to be physically inserted into an all-across press.

A perforated coil can be bound and shipped to the customer or moved to the next process once the perforating process is complete. The perforated sheets, on the other hand, may endure addition processes depending on their application, at the very least, cleaning and packing for shipment. Other finishing processes may be custom shearing into various shapes and sizes, rolling into cylinders or arches, welding, and forming into various shapes.

One process however that is rarely performed is painting. Stainless steel is designed for use without paint. Its surface is resistant to corrosion, rust, and discoloration and is rarely painted. Most paints will actually have difficulty adhering to the surface unless the surface has been sandblasted or roughed up and hand sanded.

Perforated stainless steel products are seen and used daily around the world. This product is used in many applications on the building and architectural front. It is renowned for its durability and strength, its longevity and ability to withstand the weather, as well as its pleasing appearance in aesthetic and decorative uses.

Many building facades has been designed to accommodate perforated stainless as a means of finishing the exterior. For instance, platforms and railings many times are designed using stainless steel. It is also popular with decorative accents and exterior stainless steel panels which allow light and air to pass freely while supplying a pleasing appearance.

Perforated stainless steel has infinite uses within the industrial as well as consumer markets. It is ideal for any products contacting liquids since it is resistant to rusting and corrosion. Liquid filtration, in particular, is a popular use for this amazing alloy. Perforated products in the food and medical industry are also produced in stainless steel for the same reason.

Stainless steel pipe resists bacterial growth just as it resists corrosion therefore making it the primary raw material for items that contact human consumables. It seems we can find perforated stainless steel all around us, in many instances right before our eyes throughout any given day.
