Product Description

The stainless steel square tube, a hollow strip of steel with a distinctive square cross-section, is a versatile solution for various applications. Known for its exceptional bending and torsional strength combined with lightweight properties, it is widely used in fluid transport systems including oil, natural gas, water, gas, and steam. Additionally, its robust characteristics make it ideal for the manufacture of mechanical components and engineering structures.
Our stainless steel square pipes are categorized into seamless steel pipes and welded steel pipes. The section shapes vary, encompassing square, rectangular, and the widely utilized round steel pipe. We also offer special-shaped steel pipes including semicircular, hexagonal, equilateral triangle, and octagonal forms to cater to diverse needs.
To ensure the quality and pressure resistance of our stainless steel square pipes, we conduct comprehensive hydraulic tests. These tests verify that the pipes can withstand the specified pressures without leakage, wetting, or expansion. Additionally, various tests such as crimping, flaring, and flattening are performed as per standards or specific customer requirements.
