stainless steel pipe1

Classification  of stainless steel pipe

Stainless steel pipe according to the material is divided into ordinary carbon steel pipe, high quality carbon structure steel pipe, alloy structure pipe, alloy steel pipe, bearing steel pipe, stainless steel pipe and bimetallic composite pipe to save precious metals and meet special requirements, coating and coated pipe. There are many kinds of stainless steel tubes, different uses, different technical requirements, production methods are also different. The current production of steel pipe diameter range 0.1-4500mm, wall thickness range 0.01~250mm. In order to distinguish their characteristics, steel tubes are usually classified as follows.

Folding mode of production

Stainless steel pipe according to the production method is divided into seamless pipe and welded pipe two categories, seamless steel pipe can also be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and extrusion pipe, cold drawing, cold rolling is the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.

Folded section shape

Stainless steel pipe according to the cross section shape can be divided into round pipe and irregular pipe. Special-shaped tube has rectangular tube, diamond tube, elliptic tube, hexagonal tube, eight direction tube and various sections of asymmetric tube. Special-shaped tubes are widely used in various structural parts, tools and mechanical parts. Compared with the round tube, the special-shaped tube generally has a larger moment of inertia and section modulus, a larger bending resistance, torsion resistance, can greatly reduce the weight of the structure, save steel.

Shaped seamless stainless steel pipe is a general term for seamless steel pipes with cross-sectional shapes other than round pipes. According to the different shape and size of the steel pipe section, it can be divided into equal wall thickness special-shaped seamless steel pipe (code D), unequal wall thickness special-shaped seamless steel pipe (code BD), variable diameter special-shaped seamless steel pipe (code BJ). Special-shaped seamless steel pipes are widely used in various structural parts, tools and mechanical parts. Compared with round pipes, special-shaped pipes generally have larger moments of inertia and section modulus, and have greater bending and torsion resistance, which can greatly reduce structural weight and save stainless steel.

We can provide all kinds of stainless steel tube and pipe.

Stainless steel pipe according to the longitudinal section shape can be divided into equal section pipe and variable section pipe. Variable section pipe has tapered pipe, stepped pipe and periodic section pipe, etc
