From the heart of Kinshasa, Wissa Pipes stands as a trusted partner in industrial supply, bringing strength and reliability to demanding projects across Congo and beyond. We specialize in Copper Nickel EFW (Electric Fusion Welded) pipes, a product line chosen for its exceptional performance in harsh environments. Our commitment is not just to supply materials, but to deliver durable solutions that ensure the longevity and safety of critical systems, supported by deep technical knowledge and a focus on genuine customer success.
These pipes are crafted from a sophisticated copper-nickel alloy, typically 90/10 or 70/30, which gives them a unique set of advantages. The composition naturally resists corrosion from saltwater, biofouling, and various chemicals. Mechanically, they offer excellent toughness and ductility, allowing them to withstand high pressures and physical stress without compromising their integrity. This combination of inherent corrosion resistance and reliable strength makes them a robust, long-lasting choice for piping systems.
