Product Details
Pure copper color, smooth surface.
No cracks or scratches.
It can be processed into various shapes according to actual installation requirements.
No cracks or scratches.
It can be processed into various shapes according to actual installation requirements.
Excellent electrical and thermal conductivity, better weldability and ductility, as well as good corrosion resistance and hydrogen resistance.
The copper pipe has high strength and can withstand high internal pressure.
This is particularly important in refrigeration systems, as it is not prone to rupture due to pressure changes,
making it an ideal choice for high-pressure equipment.

FAQ
Q1: Why must HVAC and air conditioning (ACR) systems use pancake copper coils? Can ordinary water pipe copper tubes be used instead?
Absolutely not. ACR-grade copper tubes undergo special degreasing and internal drying during production, and are sealed with
nitrogen to ensure no moisture, oil, or dust inside the tube. Ordinary water pipes may contain residues, which will contaminate the refrigerant and damage the compressor once entering the air conditioning system.
nitrogen to ensure no moisture, oil, or dust inside the tube. Ordinary water pipes may contain residues, which will contaminate the refrigerant and damage the compressor once entering the air conditioning system.
Q2: Why is copper purity (C12200) so important?
C12200 (Phosphorus Deoxidized Copper) usually has a purity of over 99.9%. High purity ensures excellent thermal conductivity and prevents cracks during bending and flaring Low-quality copper tubes (high impurities) are prone to electrochemical corrosion and refrigerant leakage.
Q3: How to choose the correct tube diameter according to air conditioning capacity?
It depends on the cooling capacity (tonnage or HP) of the system. 1HP -1.5HP (9k-12k BTU): Usually equipped with 1/4"(6.35mm) liquid tube and 3/8"(9.52mm) gas tube. 2HP - 3HP (18k-24k BTU): Usually equipped with 1/4" or 3/8"liquid tube and 1/2"(12.7mm) or 5/8"(15.88mm) gas tube. Recommendation: Always refer to the equipment manufacturer's service manual
Q4: If the plastic caps on the tube ends are missing upon receipt, can the tubes still be used?
Use with caution. Plastic caps maintain internal nitrogen pressure and cleanliness. If the seal fails, moisture may have entered the tube. It is recommended to purge with dry nitrogen before installation and check for obvious oxidation or impurities inside.
