Welcome to Wissa Pipes, your trusted partner for industrial solutions right here in Kinshasa. We take pride in supplying and manufacturing high-grade Stainless Steel 316H seamless pipes, engineered to meet the rigorous demands of countless industries. Our commitment is to provide not just a product, but a reliable foundation for your most critical projects, ensuring durability and performance that you can count on, backed by our local expertise and dedication to supporting Congo’s growth.
Stainless Steel 316H is distinguished by its enhanced composition. It shares the excellent corrosion resistance of standard 316, thanks to its chromium, nickel, and molybdenum content, but with a higher carbon level. This specific feature makes it particularly suited for high-temperature service, as it provides superior creep strength. This means the pipes maintain their structural integrity and resist deformation under intense heat and pressure, making them a robust choice for demanding environments.
