First, according to the mode of production: stainless steel pipe production is divided into seamless pipe and welded pipe two categories, seamless steel pipe can be divided into hot-rolled tube, cold-rolled tube, cold drawn tube and extrusion tube, Cold-rolled steel pipe is the secondary processing; welded pipe is divided into straight seam welded pipe and spiral welded pipe.

Second, according to the cross-sectional shape classification: stainless steel tube according to the cross-sectional shape can be divided into round tube and special-shaped tube. The special-shaped pipe has rectangular pipe, rhombus pipe, oval pipe, hexagonal pipe, octagonal pipe and various sections of asymmetric pipe. Shaped tube is widely used in a variety of structural parts, tools and mechanical parts. Compared with the tube, shaped pipe generally have a larger moment of inertia and section modulus, a greater bending, torsion resistance, can greatly reduce the weight of the structure, saving steel.Aisi 304 308 309s stainless steel pipe

Stainless steel tube according to the longitudinal section shape can be divided into equal cross-section tube and variable cross-section tube. Variable cross-section of possession of a tapered pipe, step-shaped pipe and periodic section of the pipe.Stainless Steel Metal Products For Sale

3, according to material classification: stainless steel pipe is divided into ordinary carbon steel pipe, high quality carbon structural steel pipe, alloy structural pipe, alloy steel pipe, bearing steel pipe, stainless steel pipe and to save precious metals and meet the special requirements of double metal composite pipe, Coating and coating tubes.Stainless Steel suppliers,steel sheets,
