Technical Description & Overview
SS pipes and tubes are available in various sizes, grades, and finishes to meet the specific requirements of different applications. Seamless and welded stainless steel pipes are the two primary types, each offering unique benefits. Seamless pipes provide higher strength and pressure resistance for high-pressure process pipelines, while welded pipes are cost-effective and widely used in structural and architectural applications. The versatility of stainless steel pipes and tubes ensures their compatibility with demanding industrial, construction, and infrastructure projects.\n\nSarvottam Steel delivers standard and custom schedule stainless steel pipes manufactured to ASTM SA 312, SA 213, SA 249, SA 269, and SA 270 standards. Every pipe undergoes rigorous inspection including hydrostatic testing, eddy current flaw detection, and pneumatic leak checks.
