What are the classifications of stainless steel pipes?

1, stainless steel pipe according to the material classificationIt 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 bimetal composite pipe, coating and coated pipe to save precious metals and meet special requirements. There are many kinds of stainless steel pipes, different uses, different technical requirements, and different production methods. The current production of steel pipe outer diameter range 0.1-4500mm, wall thickness range 0.01~250mm. In order to distinguish its characteristics, the steel pipe is usually classified according to the following method.

2, stainless steel pipe according to the production method classificationStainless steel pipe according to the production method is divided into seamless pipe and welded pipe two categories, seamless steel pipe can 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; The welded pipe is divided into straight seam welded pipe and spiral welded pipe.

3, stainless steel pipe according to the section shape classificationStainless steel pipe according to the cross-section shape can be divided into round pipe and shaped pipe. The special-shaped pipe has rectangular pipe, diamond pipe, oval pipe, hexagonal pipe, eight pipe and a variety of cross-section asymmetric pipe. Shaped tubes are widely used in various structural parts, tools and mechanical parts. Compared with the round tube, the shaped tube generally has a larger moment of inertia and section modulus, and has a larger bending and torsional resistance, which can greatly reduce the weight of the structure and save steel. Shaanxi Hualite trading Co., Ltd. main; Baosteel, Baotou Steel and other high-quality seamless steel pipes, alloy pipes and so on. The company enjoys a good reputation in the industry for operating thick wall tubes, special tubes, high-pressure boiler tubes and alloy tubes.

4, stainless steel pipe according to the shape of the pipe end classificationStainless steel pipe can be divided into light pipe and wire pipe (with rebar steel pipe) according to the state of the pipe end. Wire pipe can also be divided into ordinary wire pipe (conveying water, gas and other low pressure pipe, using ordinary cylindrical or conical pipe thread connection) and special thread pipe (oil, geological drilling pipe, for important wire pipe, using special thread connection), For some special pipes, in order to make up for the influence of thread on the strength of the pipe end, the pipe end is usually thickened before the wire is turned (internal thickening, external thickening or internal and external thickening).
