For businesses and industries in Kinshasa and across the Congo, Wissa Pipes stands as a trusted partner for robust and reliable materials. We specialize in supplying high-performance Duplex Steel Tube, providing a local solution for projects that demand exceptional strength and corrosion resistance. Our commitment is to support the growth and durability of the region’s critical infrastructure by delivering quality materials that are built to withstand the most challenging environments, right from the heart of Kinshasa.
This particular grade of tubing is defined by its unique two-phase microstructure, a balanced composition of austenite and ferrite steels. This blend incorporates elements like chromium, nickel, molybdenum, and nitrogen, which gives the tubes their signature toughness. The result is a material that offers roughly double the yield strength of standard stainless steels, along with outstanding resistance to stress corrosion cracking, making it incredibly durable under pressure and in harsh chemical conditions.
