David Pipes and Tubes, located in Canberra, Australia, stands out as a top-notch manufacturer and supplier of high-quality Copper Nickel Boiler Tubing. These tubes are crafted with meticulous attention to detail, ensuring they provide outstanding thermal conductivity, corrosion resistance, and mechanical strength—making them perfect for high-performance boiler and heat exchanger systems. Built to comply with international quality standards, Copper Nickel Boiler Tubing guarantees precise dimensions, a consistent structure, and long-lasting reliability even in high-pressure and high-temperature situations. David Pipes and Tubes caters to various industries, including marine, chemical processing, power generation, and desalination, offering robust and efficient boiler tubing solutions designed to meet demanding operational needs.
Typically, Copper Nickel Boiler Tubing consists of 10–30% nickel, with the remainder being copper, which gives it impressive tensile strength (around 300–450 MPa), yield strength (150–250 MPa), and elongation of 30–50%. This copper-nickel alloy is renowned for its excellent resistance to seawater corrosion, stress corrosion cracking, and biofouling, along with superior thermal and electrical conductivity. Its strong composition ensures reliable performance in high-temperature and corrosive settings.
