Product Description

The stainless steel square tube, a hollow, square-shaped marvel of engineering, is named for its distinctive cross-sectional shape. These tubes are fundamental in the efficient transportation of vital fluids such as oil, natural gas, water, gas, and steam. With their remarkable balance of bending and torsional strength combined with a lightweight frame, they are indispensable in the creation of mechanical components and engineering structures, serving as the backbone for countless innovations.
Stainless steel square pipes are expertly categorized into two primary types: seamless steel pipes and welded steel pipes, often referred to as welded pipes. Their cross-sectional diversity ranges from square and rectangular to more specialized shapes, such as semicircular, hexagonal, equilateral triangle, and octagonal. Though round steel pipes dominate in usage, these varied forms are designed to cater to an array of specialized applications, bringing versatility and precision to every project.
When stainless steel square pipes are subjected to fluid pressure, stringent hydraulic tests are a necessity to validate their pressure resistance and overall quality. A pipe achieves qualification if it exhibits no leakage, moisture, or dimensional alteration under designated pressures. Furthermore, these pipes may undergo additional testing procedures like crimping, flaring, and flattening to comply with industry standards or specific customer requirements, ensuring they meet the highest benchmarks of excellence.
Square tube specification: 5*5~150*150mm Thickness: 0.4~6.0mm
Square pipe material: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S
