Heat Exchanger Copper Nickel Tube
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 alloys is primary for their ability to withstand seawater corrosion, erosion and biofouling and therefore are widely used in marine and offshore industries.
C70600 - (90-10) Copper-Nickel is regular used in marine applications where resistance to both corrosion and biofouling are important.
90-10 Seamless Tubings, Annealed Temper, UNS Designation Number: 90-10 (UNS C70600).
Nominal Chemicals: Copper 88.6%, Nickel 10.0%, Iron 1.4%.
Average Mechanical Properties: Tensile 45,000 psi, Yield 18,000 psi, Elongation 35%.
Specifications: MIL-T-16420K, Type I, Grade 1, ASTM B 466.
Widely used in marine applications where resistance to both corrosion and biofouling is important.
C71500 - (70-30) Copper-Nickel is preferred to 90-10 Copper-Nickel where corrosion and temperature conditions are more severe.
70-30 Seamless Tubing, Annealed Temper UNS Designation Number: 70-30 (UNS C71500).Nominal Chemicals: Copper 69.5%, Nickel 30.0%, Iron 0.5%.Average Mechanical Properties: Tensile 55,000 psi, Yield 20,000 psi, Elongation 35%.Specifications: MIL-T-16420K, Type I, Grade 1 or 2, Annealed.Stocked in 20 foot standard lengths.70-30 Copper-Nickel tubing has excellent resistance to impingement attack and other forms of corrosion insea water. These tubes maintain their strength at elevated temperatures better than the brasses or copper.They are widely used in evaporators, feed water heaters, refinery and chemical equipment.
