Carbon Steel Pipes/Tubes
Stainless steel is a low-cost and corrosion-resistant material with a high level of durability. It is ideal for both residential and marine applications. Not only is it durable and long-lasting with a perfect surface finish, but it also has excellent strength.
Stainless Steel Seamless Pipes/Tubes are widely used in commercial and industrial fields, especially fluid transportation. With appropriate processes, they have superior performance in high pressure, high strength, and corrosion resistance.
