At Wissa Pipes, based in Kinshasa, Congo, we take pride in being a leading manufacturer and supplier of Super Duplex Steel Tubing, engineered for superior strength and corrosion resistance. Combining technical precision with a commitment to excellence, we deliver tubing solutions that perform under the most demanding conditions. Our Super Duplex products are designed for industries where reliability is critical—such as oil and gas, petrochemical, and marine engineering. With a focus on quality craftsmanship, innovation, and customer satisfaction, Wissa Pipes ensures every tube meets international standards, offering unmatched durability and long-term value for our clients worldwide.
Super Duplex Steel Tubing from Wissa Pipes is composed of a balanced mix of austenitic and ferritic stainless steels, typically containing chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen for added strength. This composition provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. The tubing exhibits impressive mechanical properties—high tensile strength up to 800–900 MPa, superior yield strength, and excellent impact toughness even at sub-zero temperatures. Its dual-phase microstructure ensures remarkable stability and performance in both corrosive and high-pressure environments.
