Liam Pipes and Tubes stands out as a top manufacturer and supplier of premium Copper Nickel Coil Tubing, proudly based in Houston, USA. We provide coil tubing in both Copper Nickel 90/10 (C70600) and 70/30 (C71500) grades, perfect for applications that need outstanding resistance to seawater, biofouling, and corrosion. Our tubing is crafted with precise dimensional tolerances, ensuring excellent formability, weldability, and mechanical performance in marine, offshore, and heat exchanger systems. By strictly following ASTM and international quality standards, Liam Pipes and Tubes delivers dependable Copper Nickel coil tubing solutions to clients around the globe in critical industrial sectors.
Copper Nickel Coil Tubing primarily comes in 90/10 (C70600) and 70/30 (C71500) compositions. The 90/10 alloy is made up of about 90% copper and 10% nickel, with small amounts of iron and manganese added to boost strength and corrosion resistance. The 70/30 alloy features a higher nickel content, enhancing its performance in more challenging environments. These alloys offer tensile strength ranging from 275 to 520 MPa, along with excellent ductility, high thermal conductivity, and remarkable resistance to biofouling, erosion, and pitting, making them ideal for continuous-run coil tubing in corrosive marine and industrial systems.
