Products Description

Our Advantages

1. High Thermal Conductivity

The Copper Coil Pipe is made from high-purity copper materials such as C10100 and C10200, with a copper content of ≥99.9%, offering excellent heat transfer efficiency.
Our copper tubes undergo rigorous chemical composition testing to ensure compliance with ASTM B75 standards, maintaining efficient energy transfer in HVAC and refrigeration systems.

2. Strong Corrosion Resistance

The Copper Coil Pipe is manufactured using a cold drawing process, resulting in a smooth and uniform surface. They also undergo eddy current testing to reduce corrosion initiation points.
The tubes are pickled, passivated, cleaned, and inspected to remove oxides and impurities from the surface.

3. Dimensional Accuracy

Our copper tubes are manufactured using precision manufacturing processes, including continuous extrusion and drawing, which ensure uniform wall thickness and consistent outer diameter. Wall thickness and outer diameter are measured in real-time during production to ensure compliance with ASTM B75 standards.
The tubes are coiled using tension control to prevent ovality, bending, or wall thinning.

4. Excellent Flexibility

Copper itself has natural ductility, and our copper coils undergo appropriate heat treatment during manufacturing to reduce residual stress and improve installation flexibility.
The tubes undergo hydrostatic pressure testing to ensure no leakage risk when coiled or bent in complex piping systems such as those used in HVAC and refrigeration systems.
