Product Description

The stainless steel square tube, a marvel of engineering, shines with its hollow, square-shaped design, aptly reflecting its name. These indispensable tubes make fluid transportation-be it oil, natural gas, water, gas, or steam-effortless. Their extraordinary blend of bending and torsional strength coupled with a lightweight construction renders them vital in crafting mechanical components and sophisticated engineering structures.
Stainless steel square pipes, a testament to versatility, are categorized chiefly into seamless steel pipes and welded steel pipes (welded pipes). These marvels of engineering come in various cross-sectional shapes-square, rectangular, and more specialized forms like semicircular, hexagonal, equilateral triangle, and octagonal. While the round steel pipes enjoy widespread popularity, these uniquely shaped pipes are crafted to cater to an array of specialized applications, offering unmatched adaptability.
For stainless steel square pipes designed to endure fluid pressure, robust hydraulic testing is paramount to assure their ability to withstand pressure while maintaining top-notch quality. Pipes that exhibit no leakage, moisture, or deformation under set pressures are deemed to excel. Furthermore, these pipes might undergo additional assessments like crimping, flaring, and flattening tests, as dictated by industry standards or customer demands, ensuring they remain at the pinnacle of reliability.
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
