ASTM B111 C68700 Copper Nickel Seamless Heat Exchanger and Boiler Tube
同昌集团供应 ASTM B111 C68700 Copper Nickel Alloy SMLS Tube in more than 70 countries. This specification ASTM B111 establishes requirements for SMLS tube and ferrule stock of copper and various copper alloys up to 3-1/8" ，inclusive， in diameter， for use in surface condensers， evaporators， and heat exchangers.
Materal C68700 resists the action of blackish water 和 high-velocity salt and is commonly used for condenser tubes. The main characteristic of C68700 is its high resistance to impingement attack. Besides， tubes of this alloys are recommended for use in Marine and Land Power Stations， in which cooling water velocities are high.
