Stainless steel pipe can be divided into ordinary carbon steel pipe, high-quality carbon structure steel pipe, alloy structure steel pipe, alloy steel pipe, bearing steel pipe, stainless steel pipe, double metal composite pipe, coating and coated pipe to save precious metal and meet special requirements.
There are various kinds of stainless steel tubes with different USES, different technical requirements and different production methods.
The outer diameter of the steel tube is 0.1-4500mm and the wall thickness is 0.01-250mm.
In order to distinguish its characteristics, steel tubes are usually classified in the following way.
Stainless steel pipe can be divided into circular pipe and special-shaped pipe according to the cross-section shape.
Special-shaped tubes include rectangular tubes, rhomboid tubes, elliptic tubes, hexagonal tubes, octagon tubes and asymmetrical tubes with various sections.
Profiled tubes are widely used in various structural parts, tools and mechanical parts.
Compared with the circular tube, the special-shaped tube generally has a larger moment of inertia and section modulus, has a larger bending, torsion resistance, can greatly reduce the weight of the structure, saving steel.
Stainless steel pipe can be divided into equal section pipe and variable section pipe according to longitudinal section shape.
The variable-section tubes are tapered, stepped and periodic.
According to the purpose can be divided into oil well pipe (casing, oil pipe and drill pipe), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high pressure fertilizer pipe, oil cracking pipe) and ship pipe.
