Renowned for their resistance to corrosion, excellent thermal conductivity, and impressive durability, Copper Nickel Boiler Tubes are perfect for marine and power generation settings. The company produces tubing that meets international standards, providing precision-engineered solutions tailored to the unique needs of their clients. With a strong foundation in technical expertise and a dedication to quality, Aman Pipes and Tubes supports industries like shipbuilding, desalination, and thermal power with dependable and long-lasting tubing products.
Copper Nickel Boiler Tubing is generally crafted from alloys like Cu-Ni 90/10 (90% Copper, 10% Nickel) or Cu-Ni 70/30 (70% Copper, 30% Nickel), with small amounts of Iron and Manganese added to boost strength and corrosion resistance. These alloys excel in resisting biofouling and seawater corrosion. The tubing boasts a tensile strength ranging from 275 to 500 MPa, a yield strength of about 120 to 190 MPa, and an elongation of 30 to 45%. Copper Nickel tubes maintain their mechanical integrity even under high pressure and temperature, providing outstanding thermal conductivity and long-lasting performance in boiler and heat exchanger applications.
