David Pipes and Tubes, located in Canberra, Australia, has built a solid reputation as a reliable manufacturer and supplier of top-notch Copper Nickel ERW Pipes. These pipes are crafted with precision using Electric Resistance Welding (ERW) technology, which guarantees uniformity, accurate dimensions, and outstanding mechanical performance. Thanks to their excellent corrosion resistance, thermal conductivity, and durability, Copper Nickel ERW Pipes are perfect for tough marine, chemical, and industrial applications. David Pipes and Tubes is dedicated to delivering dependable, high-performance piping solutions to clients in sectors like desalination, marine engineering, chemical processing, and power generation, all while ensuring quality, longevity, and consistent performance even in challenging environments.
Typically, Copper Nickel ERW Pipes consist of 10–30% nickel, with the remainder being copper, providing impressive tensile strength (around 300–450 MPa), yield strength (150–250 MPa), and elongation of 30–50%. This copper-nickel blend offers exceptional resistance to seawater corrosion, biofouling, and erosion, while also maintaining excellent thermal and electrical conductivity. The ERW manufacturing process boosts structural integrity, resulting in pipes that can be relied upon under high pressure and temperature conditions.
