Phosphorus deoxidized high residual phosphorus (DHP) copper tube for HVAC, 管道, heat exchange and gas lines.
C12200 copper tube is a phosphorus-deoxidized copper (DHP) with a minimum copper content of 99.90%. The small phosphorus addition removes oxygen from the melt, giving clean, porosity-free welds and brazes — the reason C12200 is the standard material for refrigerant lines, water pipes and heat exchangers.
