ASTM B466 , ASME SB466 C70600 Copper Nickel Seamless Pipe For Heat Exchanger
YuHong Group supplies ASTM B466/ ASME SB466 pipes and tubes. This specification establishes the requirements for seamless copper-nickel pipe and tube in straight lengths, suitable for general engineering purposes. The alloys involved are copper alloys UNS Nos. C70400, C70600, C70620, C71000, C71500, C71520, and C72200.
This page is talked about the C70600 this material, the UNS C70600 possesses some good mechanical properties, which includes good resistance to stress corrosion cracking. This material can also effectively resist erosion and biofouling in the seawater environment.
Characteristics and Applications
The Copper Nickel Alloy, prevents against seawater corrosion, high anti-fouling properties against sea microorganism. C70600 Copper Nickel Tubes / Copper-Nickel 90/10 Seamless Pipe have good corrosion resistance, especially in sea water.Widely applied to offshore and related industries such as ship-building & repairing, petrochemical, natural gas and so on.
UNS C70600 copper nickel alloys have good cold working capacity. Suitable for high temperature service.What's more, UNS C70600 copper nickel alloys are used in areas where stainless steel cannot be used due to chloride stress-corrosion cracking (CSCC) and in other parts requiring high levels of corrosion resistance.
And with the great resistance to sea water corrosion, applicable for condenser for ship, copper 90/10 and copper 70/30 are for sea water condenser systems, heat and water supply, chemical industry, desalinator etc.
