Product Description

Stainless steel square tube is a versatile hollow strip of steel, distinguished by its square cross-section. This unique shape makes it ideal for a wide range of applications, including the transportation of fluids such as oil, natural gas, water, gas, and steam. Additionally, it boasts impressive torsional strength while remaining light in weight, making it a popular choice in the manufacture of mechanical parts and engineering structures.
Stainless steel square pipe classification: Square pipes are categorized into two main types: seamless steel pipes and welded steel pipes (welded pipes). Based on sectional shape, they can be divided into square and rectangular pipes, with round steel pipes being the most common. However, there are also special-shaped steel pipes available, including semicircular, hexagonal, equilateral triangle, and octagonal shapes.
For stainless steel square pipes used under fluid pressure, rigorous hydraulic tests are essential to ensure their pressure resistance and quality. These tests check for any leakage, wetting, or expansion under specified pressures. Other tests, such as crimping, flaring, and flattening, may also be conducted according to standards or specific customer requirements.
Square tube specifications: Size range: 5*5 to 150*150 mm, Thickness range: 0.4 to 6.0 mm
Square pipe materials: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S
