HEAT EXCHANGER AND CONDENSERS COPPER ALLOY TUBES

HEAT EXCHANGER AND CONDENSERS COPPER ALLOY TUBES
Admiralty C44300 Highly resistant to general corrosion – where pressures, velocities and temperatures are moderate.
Alluminium Brass C68700 These tubes are especially adapted to resist corrosion by both salt and brackish waters.
Copper Nickel 90/10 C70600 This alloy is highly resistant to corrosion by turbulently flowing sea water indicate it to be an excellent condenser tube alloy for salt water use.
Copper Nickel 80/20 C71000 This alloy has intermediate properties between those of 10% and 30% copper nickel. Tubes of this alloy have found widest use in feedwater heaters and evaporators.
Copper Nickel 70/30 C71500 Condenser tubes of this alloy are giving long and dependable service at sea. It is also highly satisfactory for tubes in evaporators, condensers, and superheaters.
This alloy is particularly desirable where high temperatures are encountered.
