Stainless steel square tube

Stainless steel square tube is a hollow long strip of steel, called square tube because of its square cross-section. A large number of pipelines used for transporting fluids, such as oil, natural gas, water, coal gas, steam, etc. In addition, when bendingtorsional strengthWhen they are the same, they are lighter in weight, so they are also widely used in manufacturing mechanical parts and engineering structures.

Classification of stainless steel square pipes: Square pipes are divided into two categories: seamless steel pipes and welded steel pipes (welded pipes). According to the cross-sectional shape, it can be divided into square and rectangular pipes. Circular steel pipes are widely used, but there are also some irregular steel pipes such as semi-circular, hexagonal, equilateral triangle, octagonal, etc.

For stainless steel square pipes that withstand fluid pressure, hydraulic tests must be conducted to test their pressure resistance and quality. It is qualified if there is no leakage, wetting or expansion under the specified pressure. Some steel pipes also need to undergo edge rolling tests, expansion tests, flattening tests, etc. according to standards or requirements of the demand.

Square tube specification: 5 * 5~150 * 150 mm thickness: 0.4~6.0 mm

Square tube material: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S

Stainless steel rectangular tube
Stainless steel rectangular tube is a type of hollow long steel with a rectangular cross-section, hence it is called a rectangular tube. It is widely used as a scaffold frame structure, such as for oil, natural gas, water, gas, steam, etc. In addition, when bending and torsional strength are the same, it is lighter in weight, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used for producing various conventional weapons, barrels, shells, etc.

Stainless steel rectangular pipes are divided into two categories: seamless steel pipes and welded steel pipes (with seams). According to the cross-sectional shape, it can be divided into rectangular pipes and square pipes. Square pipes are widely used, but there are also irregular steel pipes.

For steel pipes that withstand fluid pressure, hydraulic tests must be conducted to test their pressure resistance and quality. It is qualified if there is no leakage, wetting or expansion under the specified pressure. Some steel pipes also need to undergo edge rolling tests, expansion tests, flattening tests, etc. according to standards or requirements of the demand.

Stainless steel rectangular tube is made by piercing steel ingots or solid billets into rough tubes, and then hot rolling, cold rolling or cold drawing them. The specifications of stainless steel rectangular pipes are expressed in millimeters by side length * side length * wall thickness.

Stainless steel rectangular tubes are used for some shallow drawn products. Surface processed products such as shallow processing cookware, indoor staircase handrails, elevators, mirrors, brushed surfaces, etc. Door and window guardrails, various brackets for anti-theft windows.
