Product Description

The stainless steel square tube is a versatile hollow strip of steel, recognized for its distinctive square cross-section. This design makes it ideal for transporting a variety of fluids, such as oil, natural gas, water, gas, and steam. Additionally, its combination of light weight and high torsional strength makes it indispensable in the creation of mechanical parts and engineering structures.
The classification of stainless steel square pipes includes two main categories: seamless steel pipes and welded steel pipes (welded pipes). Based on the section shape, they can be further divided into square and rectangular pipes. While round steel pipes are most commonly used, there are also specialized shapes such as semicircular, hexagonal, equilateral triangle, and octagonal steel pipes.
To ensure quality and pressure resistance, stainless steel square pipes subjected to fluid pressure must undergo hydraulic tests. These tests confirm that there are no leaks, wetting, or expansion under specified pressures. Additionally, some pipes may need to pass crimping tests, flaring tests, and flattening tests as per standards or customer requirements.
Square Tube Specifications: Size range: 5*5 to 150*150 mm; Thickness range: 0.4 to 6.0 mm.
Square Pipe Material Options: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S.
