Product Description

Embodying the essence of versatility and innovation, our Stainless Steel Square Tubes are a cornerstone in modern engineering. This hollow, square-shaped marvel is quintessential for a myriad of applications, such as the efficient conveyance of vital fluids-oil, natural gas, water, gas, and steam. Designed with precision, they offer an impeccable balance of bending and torsional strength, being lightweight yet robust. These tubes significantly enhance the creation of mechanical components and engineering wonders, making them indispensable to the industrial landscape.
Ingeniously crafted, our stainless steel square pipes are classified into two major types: seamless steel pipes and welded steel pipes (welded pipes). Their diversity in cross-sectional design includes square, rectangular, and exclusive shapes like semicircular, hexagonal, equilateral triangle, and octagonal, catering to a wide spectrum of specialized applications with unparalleled precision. Although round steel pipes are prevalent, our uniquely shaped options fulfill the most specific demands of niche projects with exceptional accuracy and reliability.
The unwavering reliability of our stainless steel square pipes under fluid pressure is assured through rigorous hydraulic testing-a pivotal procedure that attests to their resilience and integrity. A pipe is deemed qualified when it successfully withstands predetermined pressures, exhibiting no leaks, moisture, or expansion. To further ensure superior performance and quality, these pipes may undergo additional evaluations, including crimping, flaring, and flattening tests, meeting industry standards or specific client requirements.
Square tube specifications: Ranging from 5*5mm to 150*150mm, with a thickness spectrum of 0.4 to 6.0mm, our square tubes cater to diverse operational needs.
Square pipe materials: Available in a variety of high-grade materials such as 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, and 310S, meeting different demands for strength and resistance.
