Product Description

Embodying the essence of versatility and innovation, the stainless steel square tube is a cornerstone in modern engineering. Its hollow, square-shaped structure is quintessential for a myriad of applications, such as the efficient conveyance of vital fluids including oil, natural gas, water, gas, and steam. Designed to deliver an impeccable balance of bending and torsional strength, these tubes are lightweight yet robust, enhancing their utility in crafting mechanical components and engineering marvels. They are truly indispensable to the industrial landscape.
Ingeniously crafted, 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. Though round steel pipes are prevalent, the uniquely shaped options fulfill the precise demands of niche projects with exceptional accuracy and reliability.
The reliability of stainless steel square pipes under fluid pressure is assured through rigorous hydraulic testing, a pivotal procedure that verifies their resilience and integrity. A pipe is deemed qualified when it successfully withstands predetermined pressures, exhibiting no leaks, moisture, or expansion. Additionally, these pipes may be subjected to further evaluations, including crimping, flaring, and flattening tests, aligning with industry standards or specific client requirements, ensuring their superior performance and quality.
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
