Stainless Steel Tube Classification
Jun 11, 2018

Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, and bimetallic composite pipes, coatings, and coated pipes that meet the special requirements in order to save precious metals. . Stainless steel pipes have a wide range of types and different uses. Their technical requirements are different and their 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 its characteristics, the steel pipes are generally classified as follows.


production method

Stainless steel pipes are divided into two types: seamless pipe and welded pipe. The seamless steel pipe can be divided into hot-rolled pipe, cold-rolled pipe, cold-drawn pipe and extruded pipe. Cold-drawing and cold-rolling are the secondary of the steel pipe. Processing; welded pipe is divided into straight seam welded pipe and spiral welded pipe.

section shape

Stainless steel tubes can be divided into round tubes and shaped tubes according to the cross-sectional shape. Special-shaped tubes include rectangular tubes, diamond tubes, elliptical tubes, hexagonal tubes, octane tubes, and various cross-section asymmetric tubes. Shaped tubes are widely used in various structural components, tools, and mechanical components. Compared with round pipe, special-shaped pipe generally has larger moment of inertia and section modulus, and has greater bending and torsion resistance, which can greatly reduce the structural weight and save steel.
