YUHONG Group we are a manufacturer of copper alloy seamless tubes/pipes and we have many experiences in exporting.
ASTM B111/ASME SB111 This specification establishes requirements for seamless tube and ferrule stock of copper and various copper alloys up to 31 ⁄ 8 in. (80 mm), inclusive, in diameter, for use in surface condensers, evaporators, and heat exchangers.
Copper alloy b111 c68700 resists the action of blackish water and high-velocity salt and is commonly used for condenser tubes.
The main characteristic of C68700 is its high resistance to impingement attack. This kind of copper alloy tube is recommended for use in Marine and Land Power Stations, in which cooling water velocities are high.
