Product Description

Our stainless steel square tube, a hollow strip of steel with a square cross-section, is engineered for excellence. It's widely used in transporting fluids such as oil, natural gas, water, gas, and steam. Beyond fluid transport, its superior bending and torsional strength combined with its lightweight make it the material of choice for manufacturing mechanical parts and constructing engineering structures.
Stainless steel square pipes are categorized into seamless steel pipes and welded steel pipes. They come in various shapes including square, rectangular, semicircular, hexagonal, equilateral triangle, and octagonal. While round steel pipes are more common, these special shapes offer unique advantages for different applications.
To ensure the stainless steel square pipes meet rigorous standards under fluid pressure, hydraulic tests are performed to verify their pressure resistance and quality. Pipes that show no leakage, wetting, or expansion under specified pressure are deemed qualified. Additionally, crimping tests, flaring tests, and flattening tests may be conducted as per standard requirements or customer demands.
Square Tube Specifications: Dimensions: 5*5 mm to 150*150 mm Thickness: 0.4 mm to 6.0 mm
Square Pipe Material Options: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S
