1、Structure of Stainless Steel Seamless Pipe 316 ASTM A312 Description:

    Stainless seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.



2、Main Features of the Stainless Steel Seamless Pipe 316 ASTM A312:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Good visual effect

•Reasonable price

Q:What are the connecting methods of stainless steel pipes for indoor water pipes?
Card type features: easy to install, connecting the external pipe, the internal rubber ring is evenly compressed into hexagonal. Scope of application: cold water system, pipe direct drinking water system, and more suitable for pipe installation. The utility model has the advantages that the connection is simple and convenient, the working hours are short, and the cost is moderate. Drawback is the single application, the maintenance of trouble, both the pipe sealing ring in aging and need to be replaced more trouble, because the connection was stuck, replacement is the need to both ends of the pipe to replace the sawing.
Q:Is food grade stainless steel GB9684 304?
You can't say that.GB9684 is the implementation of standards, 304 is a material of stainless steel, stainless steel material is very much, such as 304321316347310s, 904L and so on, as long as the material of stainless steel in accordance with GB9684 standards of production and processing, can be used as a food grade stainless steel, it should be said that in accordance with the implementation of the standard GB9684 production and processing of food grade stainless steel is 304.
Q:What are the specifications of stainless steel decorative pipes?
Decorative tubes, then more specifications. Our factory has the smallest 9.5MM, the largest to see how big you can, directly with the industrial pipe to polish it
Q:Stainless steel pipes can not be less than the amount of chromium
304 stainless steel tube as 304 steel pipe, in the dry clean atmosphere, have absolutely excellent anti-corrosion ability, but it will be moved to the beach area, with large amounts of sea salt fog, will rust quickly; and the good performance of 316 steel pipe. Therefore, it is not any kind of stainless steel, capable of corrosion and rust in any environment. Stainless steel is a very thin layer formed on the surface and the stability of the fine solid chromium rich oxide film (protective film), to prevent the infiltration of oxygen atoms, to oxidation, and the ability to obtain anti-corrosion. Once there are some reasons, this film was constantly destroyed, air or liquid oxygen atoms will continue to infiltrate or metal atoms of iron to keep out from the loose formation of iron oxide, the metal surface will be continuously corroded. Many of the surface damage form, more common in daily life are as follows: 1. stainless steel surface deposited dust or heterogeneous metal particles containing other metal elements of the attachment, in the humid air, condensed water and adhesion between the stainless steel, the two together into a micro battery, cause the electrochemical reaction, the film has been destroyed, called electrochemical corrosion. 2. stainless steel surface adhesion of organic juice (such as vegetables, soup, sputum), oxygen in the water under the circumstances, a long time, organic acid, organic acid on the surface of metal corrosion. 3., stainless steel surface adhesion contains acid, alkali and salt substances (such as decoration wall caustic soda, lime water splash), causing local corrosion. 4., in polluted air (such as containing large amounts of sulfide, carbon dioxide and nitrogen oxides in the atmosphere), in case of condensation water, the formation of sulfuric acid, nitric acid, acetic acid liquid point, causing chemical corrosion.
Q:What's the difference between stainless steel decorative pipes and polished stainless steel pipes?
Stainless steel decorative tubes are mostly stainless, iron does not contain nickel, and so on, the material is slightly worse. Mainly used for interior decoration, such as interior railings, stair guards and railings, windows and so on, the thickness of the steel pipe is generally relatively thin.
Q:310 stainless steel resistance to high temperature?
American brand 310S, also known as 2520, used in high temperature furnace tube manufacturingMain features: austenitic stainless steel
Q:Why is the outer diameter of 1 inch galvanized pipe 33.7? And the outer diameter of one inch stainless steel pipe is 25.4
Some 25.4 such outer threads, is the imperial Whitworth Thread and American Standard unified thread, single head wire estimate.
Q:304 stainless steel pipe, 20*2 pressure, how many kilograms?
304 is a versatile stainless steel which is widely used in the manufacture of equipment and parts requiring good overall performance (corrosion resistance and formability).
Q:Water and electricity thin wall stainless steel tube 304 material delta 2 what does that mean?
304 stainless steel is a universal stainless steel material, antirust performance than the 200 series of stainless steel material stronger.
Q:What's the easiest way to distinguish between stainless steel 202 and 304?
304# and 202# are American Standard grade 304 is 0Cr18Ni9202shi 1Cr18Nn8Ni5N
