CuZn22 Al2 Aluminium Brass Pipe is a special alloy pipe material used in equipment working conditions with high water flow and high heat transfer. The controlled Aluminum content imparts reliable protection against erosion and corrosion damage from high speed flows of sea water, and industrial fluids, producing surface damage. It is appropriate for use in condenser systems, heat exchangers, marine cooling systems and other fluid line equipment requiring a consistent service life. The pipes may be provided in standard or customized sizes, as per the requirements of the equipment design and installation. Reliable performance in production and service are achieved by proper material certification and dimensional control. USA Piping Solution produces and distributes CuZn22 Al2 Aluminium Brass Pipes for general marine, power generation and industrial heat transfer applications throughout the world.
