How to Use Stainless Steel Pipe in Water Supply System?
We will give you some information about how to use stainless steel pipe in water supply system. We hope it can offer you some help. The most common stainless steel pipes used to supply water are 304 seamless stainless tube and 316 stainless steel pipe. They can meet most of the water treatment and transportation requirement.
Basically, 304 seamless stainless tube is made of austenitic stainless steel. And 316 stainless steel pipe contains molybdenum element. So 316 stainless steel pipe has a better ability of resisting pitting and crevice corrosion than 304 stainless steel pipe. So knowing how to use stainless steel pipe, especially 304 seamless stainless tube and 316 stainless steel pipe is quite important. If the pipe system needs to use welding method, it is better to use 304L stainless steel pipe or 316L stainless steel pipe which contains low carbon steel or 316i stainless steel which contains titanium. If we use 304 seamless stainless tube and 316 stainless steel pipe, some necessary processing measures should be adopted, such as controlling welding current and welding speed. The best welding effect is silvery or golden welding lines.

How to Deal with Stainless Steel Pipe Type?
Stainless steel pipes can be divided into two main types:seamless stainless tube and welded stainless steel pipe. And the seamless stainless tube can be divided again in to four smaller types: hot-rolled pipe, hot-rolled pipe, cold drawn pipe and extruded tube. And the welded stainless steel pipe can be also divided into two smaller types: longitudinal welded pipe and helical weld pipe. The second method to deal with the stainless steel pipe type is to classify the stainless steel pipes depending on the sectional form.
According to the sectional form, the stainless steel can be divided into circular pipe and special section pipe. It is easy to understand the meaning of circular pipe, but not easy to make sense with the concept of special section pipe. Just as its name implies, special section pipe means rectangular pipe, diamond shape pipe, oval pipe, six-point pipe, eight-point pipe and other asymmetric pipes. The third method to deal with the stainless steel pipe type is to classify the stainless steel pipes depending on texture. According to different texture, stainless steel pipes can be divided into: common carbon steel pipe, high quality carbon steel pipe, alloy structure pipe,alloy steel pipe, and so on.

There is a wide range of stainless steel pipe type. Because the technical requirements and applications are different, the production method processes of stainless steel pipes are different as well

What Is Stainless Steel Pipe Features?
Stainless steel pipe features contain several aspects and one of the most outstanding one is that it is stainless and cannot be ruined by the factors that affect most of the iron materials. Stainless steel will not be corrupted by the moisture and humid like the iron pipe and it is of better strength and hardness. Among the many stainless steel pipe features, this one is quite unique and it is contributed by the component of stainless steel, which is carbon. Black steel pipe is not stainless steel pipe, for the material form up black steel pipe is not stainless steel but a new kind of plastics. So black steel pipe features are not quite the same like stainless steel features. Black steel pipe is also against moisture and humid weather, but is much softer than the stainless steel pipe. Since most plastic cannot reach to the same hardness level as stainless steel does.

Overview of Carbon Steel Weld Ability
Carbon steel electrode and gas selection is pretty easy. In most cases the filler wire will be “ER70s-6”. The gas choices are either straight Co2 or a C25 Gas that consists of 25% Carbon Dioxide and 75% Argon. The C25 mixture does produce better weld quality but also cost a bit more.
Beside the gasses and electrode mentioned above there are many electrodes, mixtures and combinations that can also be used.
Welding carbon steel pipe is easy and does not have any real obstacles. It welds fine in all positions and produces a quality weld. The only possible issue could be from welding in the vertical up position. This position typically requires a groove because the weld is always very convex. Another issue to watch out for is cold lap. Brightstainless welding can produce poor quality welds if the welder is not run hot enough. Besides that it is a excellent choice for welding in a shop because it makes good welds that are clean and require very little dressing. Spatter can be a issue once in a while but that is solved with anti-spatter spray or just a light scraping after welding.

Application of Stainless Steel in Electric Heating
The hot water heater is mainly composed of heating plate, pressure sensor, power regulator, water regulating faucet, inlet pipe and outlet pipe fittings. The heating plate is the key part of the hot water heater. The heating tank consists of tank weights, seals, covers and heating elements. The heating element is located in the groove of the slot plate and is also generally referred to as the interior of the hot water heater. The use of stainless steel heating pipe as a heating body of the hot water heater, cold water into the liner directly through the stainless steel pipe surface and be heated.
Stainless steel electric heating pipe is the current use of electric water heater industry, the most used a way of heating.
The advantages of stainless steel heating pipe is: heat resistance is better, resistant to dry, more mature technology, the cost is relatively low. At present, the hot water heater manufacturers are using more types of stainless steel pipe, a variety of pipe price gap. The same is the stainless steel electric heating pipe, the quality performance difference is very large. Stainless steel heating pipe material is the difference between the quality of nickel is mainly different, nickel is an excellent corrosion-resistant materials, stainless steel and chromium with the stainless steel after the corrosion resistance and process performance to obtain some improvement. However, low-carbon nickel steel to obtain pure austenite, nickel content to reach 24%, and only 27% of nickel when the steel in some media corrosion resistance significantly changed. Therefore, from the material point of view 800,840,316 L is relatively good corrosion resistance and high temperature stainless steel heating pipe, 800 stainless steel pipe with nickel content of 30%, 840 pipe nickel content of 20%, but if it is poor Some of the 304 tube stainless steel contains only 8% nickel. Therefore, the use of high nickel content of high
temperature corrosion-resistant stainless steel heating pipe products are also very advantageous.

1.Welded pipe for delivering low-voltage fluid (GB/T3092-1993). This kind of pipe also known as general
welded pipe, or black pipe, which is mainly used for delivering low-voltage fluid, including water, oil and gas etc. The specifications of pipe are presented by nominal diameter, which is the approximation of inner diameter. Traditionally, the diameter is expressed by inches, such as 11/2 etc. Besides directly delivery fluid, the pipe is widely applied as raw pipe of galvanized welded steel pipe for fluid.
2. General welded carbon steel wire casing (GB3640-88). This kind of welded pipe is commonly applied in industrial and civil construction, and installation of electrical equipment, plays a role of a protector for electrical wires.
3.Straight seam welded steel pipe (YB242-63). This kind of pipe can be divided in to metric welded pipe, welded thin-walled tube and transformer cooling tube, etc.
4. Spiral welded pipe for delivering pressurized fluid (SY5036-83). This type of pipe use hot-rolled strip for the tube, welded with double-sided submerged arc, and applied in delivering pressurized fluid.
The pipe has excellent strength and welding performance, have passed strict scientific examinations and
tests, reliable for use. The pipe has a large diameter with high transmission efficiency, and can save
the cost of laying pipelines. Commonly used to conveying oil and gas.
5.General spiral submerged welded pipe for low-pressured fluid (SY5037-83). This type of use hot-rolled
strip for the tube, welded with double-sided submerged arc, commonly used for delivering of water, gas, air, stream and other low-pressured liquid.

How Do We Make Seamless Stainless Tubes?
Specialty seamless stainless tubing is used in many applications, including the flow of gas, steam and liquid in harsh environments. Some manufacturers specializing in this field produce seamless, stainless steel tubing ranging from one inch in diameter to finer than a human hair, and in continuous lengths that can exceed a mile.
Typical methods for manufacturing seamless stainless steel tubing are by extruding, gun drilling or piercing. However, the extrusion process provides the most uniform OD (outside diameter) and ultimately the most concentric ID (inside diameter). In addition, extrusion is the only process most suitable for long length seamless stainless steel coil tubing. At this point the raw material is processed through tube reducers known as pilger mills in a long straight form.
Cold pilgering is able to maintain uniform ODs and concentric IDs because it is a longitudinal cold-rolling process which reduces the diameter and wall thickness of steel tube in one operation. For specific material types this process achieves cross-section reductions of more than 90 percent in a single working cycle.
Lubricants are used on the OD and ID when reducing the tube, which is then degreased in preparation for annealing. This process typically produces lengths from around 40 feet to 160 feet in length after reduction. Cold reducing is the most effective method when manufacturing long lengths of seamless tubing that are to be processed in coil form.
