Applications

Copper nickel tube is used for a variety of industries; Including marine environments, power generation, offshore, oil & gas and defence sectors. Drawn copper nickel tube combines cold and hot working properties, highest degree of seawater corrosion and erosion resistance and great strength. Typical users are distillation and desalination plants and marine coolers and heat exchangers.

Features:

Applied vacuum melting technology, our tubes are of superior quality: Stable chemical composition, precise dimensions, and clean, smooth and bright inner and outer surface. Good mechanical properties - free from defects such as blowholes, cracks, pin hole leaks etc.
* Good corrosion resistance, especially in sea water;
* Suitable for high temperature service;
* Applicable for condenser for ship, heat and water supply, chemical industry, desalinator etc.
* Copper Alloy UNS Nos. C70600 and C71500 are seamless Copper Nickel Tubes of standard specifications for Water Desalting Plants.
