Stainless Pipe, hollow structure, usually cylindrical, is used primarily to convey liquids, gases, or solids suspended in a liquid, e.g., a slurry. It is also used as a conduit for electric wires. Sometimes it is used as a steel structure.
Stainless steel characteristically has a minimum Of 10.5% chromium by weight. means has a larger percentage of chromium in it as compared to carbon steel, which is what grants it the ability to resist corrosion.
Below are the Standards and Material grades for Stainless Pipes:

There are two(2) sub-categories for Stainless Steel Pipes. These are Stainless Steel Seamless Pipes and Stainless Steel Welded Pipes.
Stainless Steel Seamless Pipes
Seamless (SMLS) 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.
Stainless Steel Welded Pipes
Welded Pipes is manufactured by rolling metal and then welding it longitudinally across its length, therefore welded pipes have a welded joint in its cross-section. It can be ERW, EFW, LSAW, SSAW.
