Application:
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.
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.
Copper Nickel Tube are one of our core products, we produce to the widest size range in outside diameter, length and wall thickness. Our seamless Copper Nickel (CU NI) pipes have a outside diameters range of between 0.5mm to 330mm. Our copper nickel tube welded pipes have an outside diameter range of 100 mm 20, 000 mm and we can manufacture upto lengths of 15m! We are also able to offer single continuous weld lines on our welded pipes.
We are extremely proud of our tube production capabilities and have invested heavily in the future as we believe cu-ni tubing will play a key part in developing technologies. This along with our commitment to service excellence we believe is the reason why our customers keep choosing us for their tubing and piping requirements. Our large annual production volume of cupronickel tube allows us to maintain a large stock program inventory. We can meet customer requirements and expectations with rapid production of tubes and fast delivery times.
