Impex Tube India, Mumbai, India, is a top supplier and producer of high-strength industrial tubing and piping solutions. Our Copper Nickel Boiler Tubing which is produced using copper-nickel alloy (90% copper, 10% nickel), is corrosion-resistant, of high strength, and long-lasting. This tubing is produced in a range of shapes and sizes and can withstand high temperatures and hostile environments. Used predominantly in heat exchangers, boilers, and steam applications, Copper Nickel Boiler Tubing provides superior corrosion resistance in high-usage industrial applications, such as power and marine industries.
Composed primarily of mainly 90% copper and 10% nickel with further corrosion protection against seawater and acidic environments, Copper Nickel Boiler Tubing also contains traces of manganese and iron for further strength and resistance. It is mechanically high in tensile strength with good elongation and stress corrosion cracking resistance. It also has a high thermal conductivity making it suitable for heat exchange applications. It is physically stable at high pressure and temperature, with long-term performance and reliability in marine, power and industrial applications.
