ASTM B111 UNS C12200 / CW024A Seamless Copper Tube , DHP Heat Exchanger Tube
ASTM B111 UNS C12200 / CW024A Copper Alloy Seamless Condenser Tubing
Phosphorus-Deoxidized copper tubes (DHP) – C12200 has similar corrosion resistance to C11000. It gives excellent resistance to weathering and very good resistance to many chemicals. It is often used specifically for corrosion resistance, which extensively used in sugar refineries for condensers and evaporators. Deoxidized copper is the standard material for transferring heat from steam to water or air because of their excellent resistance to corrosion by fresh water and their high thermal conductivities.
