2B BA 304 310 316 Stainless Steel Pipe

According to the weld form is divided into straight seam welded pipe and spiral welded pipe.
According to its use, it is divided into general welded pipe, heat exchanger pipe, condenser pipe, galvanized welded pipe, oxygen blown welded pipe, wire casing, metric welded pipe, roller pipe, deep well pump pipe, automobile pipe, transformer pipe, electric welded thin-wall pipe, electric welded special-shaped pipe and spiral welded pipe. GB/T12770-2002(Stainless Steel Welded Steel Pipe for mechanical structures). Mainly used in machinery, automobile, bicycle, furniture, hotel and restaurant decoration and other mechanical parts and structural parts. Its representative material 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb and so on.

GB/T12771-2008(Welded Stainless Steel Pipe for fluid transportation). Mainly used for conveying low pressure corrosive media. The representative material is 06Cr19Ni10, 022Cr19Ni10, 06Cr19Ni110Ti, 00Cr17, 0Cr18Ni11Nb, 06Cr17Ni12Mo2, etc.

Stainless steel pipe is a kind of hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial pipelines and mechanical structural parts. 

In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in manufacturing mechanical parts and engineering structures. It is also used for furniture, kitchenware, etc. The hardness of stainless steel pipe is usually measured by Brinell, Rockwell and Vickers. Annealed stainless steel pipe with inner diameter of more than 6.0 mm and wall thickness of less than 13 mm.
