ASME SB111 C68700 Aluminum Brass Steel Tube for Marine and Land Power Station
Continuous B111 grade C68700 Aluminum Brass Pipe is robust and corrosion-resistant. In industries such as air conditioning units, heat exchanger tube, freezers, the petrochemical sector, power plants, etc., ASTM B111 C68700 Tube is frequently used.Condenser pipes frequently employ the material C68700 because it withstands the effects of salt water and black water moving at incredible velocities. The significant resistance of C68700 to compressive damage is its primary feature.
For usage in marine and terrestrial power stations with significant cooling water velocity, pipes made of this alloy are advised. In “Seawater desalting plants,” C68700 aluminum brass pipes are frequently utilized. The UNS C68700 tube is thin, has excellent heat conductivity, and has a significant of low-temperature strength.
