Product Description

Stainless steel square tube, a hollow strip of steel with a square cross-section, is designed for a multitude of applications. Its square shape makes it ideal for transporting various fluids such as oil, natural gas, water, gas, and steam. Additionally, its combination of light weight with high bending and torsional strength makes it an excellent choice for the manufacture of mechanical parts and engineering structures.
Stainless steel square pipes can be broadly classified into two categories: seamless steel pipes and welded steel pipes (also known as welded pipes). Depending on the section shape, these pipes are available as square and rectangular pipes. The most commonly used type is round steel pipe, but specialized shapes like semicircular, hexagonal, equilateral triangle, and octagonal steel pipes are also available to meet diverse needs.
For stainless steel square pipes that will be subjected to fluid pressure, rigorous hydraulic tests are conducted to ensure their pressure resistance and overall quality. Only pipes that show no signs of leakage, wetting, or expansion under specified pressure are deemed qualified. Additionally, some steel pipes must undergo crimping tests, flaring tests, flattening tests, and other evaluations as per the standards or specific requirements of the customer.
