304L Stainless Steel Seamless Pipe – Low Carbon Sanitary Grade
Product Overview
304L stainless steel seamless pipe is the low-carbon variant of standard 304, specially designed for welded piping systems and corrosion-sensitive applications. With carbon content limited to 0.03% maximum, it eliminates the risk of intergranular corrosion in weld heat-affected zones, ensuring long-term reliability in welded pipework. This sanitary-grade seamless pipe is the industry standard for food processing, pharmaceutical, beverage and sanitary fluid transfer systems.
Why Choose CNB 304L Stainless Pipe?
Our 304L seamless pipes are produced by leading precision tube mills with strict control of carbon content, dimensional accuracy and surface quality. Every pipe undergoes full nondestructive testing including eddy current and ultrasonic inspection to ensure defect-free quality. We supply both standard industrial and high-purity sanitary grades, with various surface finishes and end preparations to match different application requirements.
