Product Description
ASTM T2 Seamless Red Copper Tube is a high-purity copper pipe manufactured from Cu-DHP (phosphorus-deoxidized copper) with a copper content of at least 99.90%. Designed for refrigeration, air conditioning, plumbing, water supply, and heat exchange systems, it offers excellent thermal conductivity, corrosion resistance, and mechanical strength.
Manufactured according to ASTM B88, ASTM B837, ASTM B306, ASTM B883, and ASTM B819 standards, the tube is available in straight lengths and coils with outer diameters from 6.35 mm to 406 mm and wall thicknesses from 0.5 mm to 80 mm. It is suitable for both residential and industrial applications requiring reliable heat transfer and long service life.
Modern HVAC, refrigeration, and water distribution systems require piping materials that can withstand high pressure, temperature fluctuations, and corrosive environments while maintaining excellent thermal efficiency.
- Traditional steel pipes may rust and corrode over time
- Reduced heat transfer efficiency with traditional materials
- Frequent maintenance requirements
- Increased installation costs due to heavier weight
- Refrigeration systems demand internally clean tubing to prevent compressor contamination and system failure
T2 Seamless Copper Tube provides an ideal solution by combining:
- High thermal conductivity for efficient heat transfer
- Excellent corrosion resistance for long service life
- Seamless construction for higher pressure resistance
- Superior ductility for easy bending and installation
- Internal cleanliness meeting EN 12735-1 requirements for refrigeration applications
- Compatibility with water, refrigerants, lubricants, and HVAC systems
Its seamless manufacturing process minimizes leakage risks and improves operational reliability.
