Applications
- Air Conditioning Systems: Ideal for connecting outdoor condenser units to indoor evaporator coils in split ACs and central HVAC systems
- Refrigeration Equipment: Used in refrigerators, freezers, and commercial cold storage units for refrigerant lines
- Industrial Heat Exchangers: Suitable for industrial machinery requiring efficient heat dissipation
- Gas & Water Supply: Applicable for plumbing and fuel lines in specialized environments due to excellent corrosion resistance
Working Principle
The efficiency of this copper tubing lies in its seamless structure and high thermal conductivity.
- Thermal Transfer: Copper's high thermal conductivity coefficient enables efficient heat absorption from indoor environments (evaporation) and heat release outdoors (condensation). The 99.9% pure copper content minimizes energy loss during this process.
- Seamless Integrity: Unlike welded pipes, seamless tubing has no longitudinal weld seams, eliminating weak points and ensuring the tube can withstand high refrigerant pressures (such as R-410A) without bursting or leaking.
- Corrosion Resistance: The natural oxide layer on copper protects the tubing from internal chemical reactions with refrigerants and external environmental corrosion, ensuring longevity that matches the supported machinery.

Frequently Asked Questions
What is the difference between C12000 and T2 copper?
C12000 is a phosphorus-deoxidized copper known for excellent weldability and corrosion resistance in high-temperature environments. T2 is pure copper (99.9%) offering superior electrical and thermal conductivity. Both are available in our inventory and are suitable for HVAC applications.
Can you customize the diameter and wall thickness?
Yes. We offer fully customizable specifications. The outer diameter can range from 3mm to 360mm, and wall thickness can be customized from 0.1mm to 50mm to meet specific project requirements.
Do you supply this tubing in coils or straight pieces?
We supply both. Coils are ideal for long runs without joints (reducing leak risks), while straight pipes are preferred for rigid infrastructure and precise industrial applications.
What processing services do you offer?
We support value-added processing including bending, decoiling, welding, punching, and cutting to ensure the product is ready for installation upon arrival.
What are the payment terms and minimum order quantity?
The MOQ is 100 kg. Payment terms are flexible, typically L/C or T/T with a 30% deposit.
