C12200 Tube Manufacturer
We are a professional manufacturer and global supplier of copper tubes and copper pipes, including TP2 copper tube (GB/T) and C12200 copper tube (ASTM).
These products are widely used in HVAC systems, refrigeration, air conditioning, plumbing, heat exchangers, water supply, gas pipelines, and industrial applications due to their excellent thermal conductivity, corrosion resistance, and formability.
C12200 (Phosphorus-Deoxidized Copper, DHP) and TP2 copper are among the most commonly used copper tube materials worldwide.
What Is C12200 / TP2 Copper?
C12200 (TP2) is a high-purity copper alloy containing a small amount of phosphorus, which provides:
- Excellent weldability and brazability
- High thermal and electrical conductivity
- Good corrosion resistance
- Resistance to hydrogen embrittlement
- Long service life
TP2 or C12200 is also known as Cu-DHP in EN grade,whichis a phosphorus-deoxidized copper with a limited, high amount of residual Phosphorus.
Cu DHP refers to (Deoxidized High Phosphorus) copper. our C12200 tubes are widely used in heat exchangers, refrigeration systems, HVAC, plumbing, and industrial piping due to their excellent corrosion resistance, thermal conductivity, and weldability.
C12200 Phosphorus deoxidized, high residual phosphorus can be produced according to ASTM B75.
