ASTM B111 Annealed O61 C71640 / CW353H Copper Nickel Alloy Seamless Tube for Heat Exchanger
同创集团 supply copper alloy tubes containing grade C44300， C68700， C71500， C70600， C12200， etc. Tubes in a variety of sizes widely used for marine applications， condenser， heater， equipment， etc.
66-30-2-2 Cu-Ni (C71640， CW353H) Tube is a modified version of 70-30 alloy tube and contains 2% iron and 2% Mn and can withstand higher flow rates than 90-10 and 70-30. The other important note is that it has slightly less resistance to localized corrosion. These C71640 products are mainly used as condenser tubing. Commercially， UNS C71640 condenser tubes are mainly in demand by Industrial Plants. It was originally developed for higher resistance to erosion corrosion in the presence of suspended solids and has been extremely successful in multi-stage flash desalination plants， particularly in the heat rejection and brine heater sections.
Advantage of CuNi Tubes:
- 合金系统简单，焊接性能良好
- 出色的延展性和韧性
- 出色的侵蚀腐蚀性能
- 抗均匀和局部腐蚀
- 环境海水温度无影响
- 海水氯化无影响
- 抗生物污染
- 抗应力腐蚀开裂
- 维护成本低
- 丰富的设计经验
