Product Description

Introducing the versatile stainless steel square tube: a hollow, square-shaped marvel of engineering crafted from robust steel. Perfectly named for its unique cross-sectional shape, these tubes are indispensable in applications that involve the transport of various fluids such as oil, natural gas, water, gas, and steam. They boast an extraordinary combination of bending and torsional strength while maintaining a lightweight profile, making them an essential component in the creation of mechanical parts and engineering structures.
Stainless steel square pipes are expertly classified into two primary types: seamless steel pipes and welded steel pipes (welded pipes). These pipes can assume various cross-sectional shapes including square, rectangular, and even more specialized forms such as semicircular, hexagonal, equilateral triangle, and octagonal. Although round steel pipes are traditionally the most prevalent, these diverse configurations cater to a multitude of specialized applications, broadening their utility across various industries.
For stainless steel square pipes that operate under fluid pressure, conducting rigorous hydraulic tests is crucial to affirm their pressure resistance and overall quality. A pipe earns its certification if it successfully withstands specified pressures without exhibiting leakage, moisture, or expansion. Additionally, these pipes may be subjected to crimping, flaring, and flattening tests as dictated by industry standards or specific customer requirements, ensuring they meet the highest quality benchmarks.
Square tube specification ranges from 5*5 mm to 150*150 mm, with a thickness spectrum extending from 0.4 mm to 6.0 mm.
Crafted from premium materials, the square pipe selection includes 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, and 310S, offering a variety of options tailored to specific applications.
