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, coating and coating pipe to save precious metals and meet special requirements. There are many kinds of stainless steel tubes, different uses, different technical requirements, production methods are also different. The current production of steel pipe outside diameter range 0.1 -- 4500mm, wall thickness range 0.01 ~ 250mm. In order to distinguish their characteristics, steel pipes are usually classified as follows.

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.

Section shape
Stainless steel pipe according to the cross section shape can be divided into round pipe and special-shaped pipe. Special-shaped tube has rectangular tube, diamond tube, elliptic tube, hexagonal tube, eight party tube and a variety of cross-section asymmetric tube. Profiled 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, has a larger bending and torsional resistance, can greatly reduce the weight of the structure, save steel.

Stainless steel pipe according to the profile shape can be divided into equal section pipe and variable section pipe. The variable section pipe has conical pipe, stepped pipe and periodic section pipe.

Pipe end shape
Stainless steel pipe can be divided into light pipe and wire pipe (with spiral 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 (petroleum, geological drilling pipe, for important 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, Tube end thickening (internal thickening, external thickening or internal and external thickening) is usually carried out before wire drawing.

What are the uses of seamless steel pipe

Seamless steel pipe has hollow section, widely used for conveying fluid pipeline, such as conveying oil, natural gas, gas, water and some solid materials, etc. Compared with solid steel such as round steel, steel pipe is a kind of economic section steel because of its light weight and the same bending and torsional strength.

Performance index of steel pipe

The mechanical property of steel is an important index to guarantee the final serviceability (mechanical property) of steel, which depends on the chemical composition and heat treatment system of steel. In the steel pipe standard, according to different use requirements, the tensile properties (tensile strength, yield strength or yield point, elongation) and hardness, toughness indicators, as well as user requirements of high, low temperature performance.
