What are the stainless steel tubes?

1. Stainless steel pipe 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 to save precious metal and meet special requirements, coating and coating pipe, etc.. Stainless steel tubes are of various kinds, different uses, different technical requirements, production methods are also different. The current production of steel pipe diameter range of 0.1-4500mm, wall thickness range of 0.01-250mm. In order to distinguish their characteristics, the steel pipes are usually classified as follows.

2. Stainless steel pipe according to the production mode 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, etc., cold drawn, cold rolled steel pipe is the secondary processing; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.

3 section shape stainless steel tube according to the cross section shape can be divided into round tube and special-shaped tube. Special-shaped pipe has rectangular pipe, diamond pipe, elliptic pipe, hexagonal pipe, eight direction pipe and all kinds of asymmetrical section pipe. 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, has a greater ability to resist bending and torsion, can greatly reduce the weight of the structure, save steel. Shaanxi Hualite Trading Co., LTD. Baosteel, Baotou steel and other high quality seamless steel pipe, alloy pipe, etc. The company is well known in the industry for its heavy wall pipe, special pipe, high pressure boiler pipe and alloy pipe. Stainless steel pipe can be divided into equal section pipe and variable section pipe according to longitudinal section shape. Variable section tube has conical tube, step tube and periodic section tube, etc.

4. The shape of the pipe end stainless steel pipe can be divided into light pipe and wire pipe (with rebar pipe) according to the state of the pipe end. Turning wire pipe can be divided into ordinary turning wire pipe (conveying water, gas and other low pressure pipe, using ordinary cylindrical or conical pipe thread connection) and special threaded pipe (petroleum, geological drilling pipe, for important turning wire pipe, using special thread connection), for some special pipe, in order to make up for the influence of thread on the strength of the pipe end, The pipe end is usually thickened (inside, outside or inside) before the wire is turned.
