Product Description

Stainless steel square tube is a versatile, hollow strip of steel characterized by its square cross-section. This unique shape makes it ideal for transporting various fluids such as oil, natural gas, water, gas, and steam. Its lightweight design, combined with strong bending and torsional strength, also makes it a preferred choice in the manufacturing 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). Depending on the section shape, these pipes can be square, rectangular, or other shapes such as semicircular, hexagonal, equilateral triangle, and octagonal. While round steel pipes are widely used, these special-shaped pipes also find their niche applications.
For stainless steel square pipes subjected to fluid pressure, rigorous hydraulic tests must be conducted to assess their pressure resistance and overall quality. Pipes are deemed qualified only if they show no signs of leakage, wetting, or expansion under the specified pressure. Additionally, some pipes may undergo crimping tests, flaring tests, flattening tests, and more, based on established standards or customer requirements.

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