Wissa Pipes, a reputable manufacturer and supplier located in Kinshasa, Congo, specializes in high-quality Stainless Steel EFW (Electric Fusion Welded) Pipes. These pipes are celebrated for their outstanding corrosion resistance, sleek finish, and remarkable strength. Crafted using cutting-edge electric fusion welding techniques, they guarantee precise dimensions, robust weld integrity, and long-lasting durability. Wissa Pipes produces EFW pipes that comply with international standards, making them perfect for industries like chemical, petrochemical, food processing, and power generation. With their reliable performance in high-pressure and high-temperature settings, these Stainless Steel EFW Pipes are built to endure oxidation, scaling, and corrosion over time.
Stainless Steel EFW Pipes primarily consist of chromium (16–20%), nickel (8–12%), along with trace amounts of molybdenum, manganese, and carbon, depending on the specific grade. They boast a tensile strength ranging from 500–750 MPa, a yield strength of about 200–400 MPa, and an elongation of 35–40%. The EFW process results in strong, consistent welds that offer enhanced resistance to corrosion and high temperatures. These pipes showcase excellent mechanical properties, toughness, and oxidation resistance, making them ideal for high-pressure fluid systems, heat exchangers, and structural applications in both industrial and marine settings.
