What is Copper Nickel Pipe ?

Copper-nickel pipe is a pipe made from copper-nickel alloy with copper content of around 90% and nickel content of 10%, and it is used mostly in industries that require highly corrosion & wear resistance material, which can particularly be used for marine applications.

Copper-nickel pipes are especially suitable for application in marine installations, including marine ship building, offshore oil and gas installations, desalinated water systems, and heat exchanging systems, because they offer excellent resistance to salt water and marine organisms.

Similarly copper-nickel tube is also employed for such uses as marking the tube copper nickel tube which is merely a smaller and more pliable variety of the first construction and holds the similar buoyancy against corrosion and composition hardness as before. These tubes are particularly appropriate for heat exchangers, chemical processing plants as well as power plants because of high heat transfer rates and ability to withstand chemical attack. buy directly from copper nickel tubes manufacturers in india to get factory rate

Copper with 70% and Nickel with 30% make the alloy (C71500) more resistant compared to other types of environments. Copper-nickel pipes and tubes have properties of high thermal conductivity, enabling greater production rates of heat transfer through pipes and tubes during fabrication, and longevity to increase the time between maintenance and replacement objectives.

Due to their mechanical properties and corrosion resistance they have become the material of choice for piping in many industries where reliability and durability are paramount. Tubotech is Finest quality  Copper Nickel Pipe Manufacturer in India Since 20 years.
