Samia Pipes and Tubes, located in Tunis, Tunisia, has earned a solid reputation as a reliable manufacturer and supplier of top-notch Copper-Nickel EFW (Electric Fusion Welded) pipes. These pipes are specifically designed to meet the rigorous demands of industrial, marine, and chemical applications. Crafted with precision, their Copper-Nickel EFW pipes boast remarkable strength, corrosion resistance, and durability, making them particularly effective in environments that face seawater or harsh chemicals. Thanks to their advanced manufacturing techniques and strict quality control measures, Samia Pipes and Tubes is dedicated to delivering products that perform exceptionally well across a range of challenging scenarios. The superior corrosion resistance of Copper-Nickel EFW pipes makes them a go-to choice for marine, offshore, and other tough environments.
These pipes are made from an alloy that primarily consists of copper and nickel, typically featuring a composition of 70% copper and 30% nickel, along with small amounts of iron and manganese. The Electric Fusion Welding (EFW) technique is employed to seamlessly join the edges of the pipe, where electric currents heat the material until it fuses together. This process results in a strong, dependable weld while reducing the chances of defects. Copper-Nickel EFW pipes are known for their excellent corrosion resistance, especially in seawater, as well as their good strength, weldability, and resistance to stress corrosion cracking. These characteristics make them ideal for high-pressure and high-temperature applications.
