Wissa Pipes stands out as a leading manufacturer and supplier of Stainless Steel Welded Pipes right from Kinshasa, Congo. We take pride in delivering top-notch piping solutions tailored for a variety of industrial needs. Our Stainless Steel Welded Pipes are crafted using cutting-edge welding techniques, ensuring they boast exceptional precision, corrosion resistance, and durability. Built for efficiency and longevity, these pipes come in various grades, sizes, and finishes to align with global standards. Wissa Pipes provides Stainless Steel Welded Pipes that cater to industries like petrochemical, construction, marine, food processing, and pharmaceuticals, guaranteeing reliability and performance in every application.
When it comes to composition and mechanical properties, our Stainless Steel Welded Pipes are mainly made up of iron, chromium (16–20%), nickel (8–12%), along with trace amounts of molybdenum, carbon, and manganese, depending on the specific grade (like 304, 316, or 321). This unique blend gives them outstanding corrosion resistance, strength, and the ability to withstand oxidation, even at high temperatures. The pipes showcase a tensile strength ranging from 500–750 MPa, a yield strength of about 200–500 MPa, and remarkable ductility and formability. Plus, they feature smooth internal surfaces, excellent weld integrity, and long-lasting mechanical stability, making them perfect for both high-pressure and corrosive environments.
