Our ASTM B280 C12200 TP2 Pancake Coil Copper Tube is a premium, alloy-free solution engineered for exceptional reliability and efficiency in air conditioning and refrigeration systems. Manufactured from phosphorus deoxidized copper (C12200/DHP) with a minimum 99.99% Cu content, this soft-temper tube offers superior corrosion resistance, excellent heat conductivity, and remarkable formability. The unique "pancake coil" configuration ensures compact storage, easy handling, and reduced installation time on the job site.
This copper pipe is produced in full compliance with international standards including ASTM B280, EN 12735-1, and JIS H3300. It comes pre-cleaned, nitrogen-charged, and sealed at the ends to prevent oxidation and contamination, guaranteeing system integrity right out of the packaging. Optional fire-retardant insulation with certified low thermal conductivity (≤0.033 W/mK at 0°C) is available for enhanced energy efficiency and safety. We offer complete customization from bending and cutting to precise sizing, supported by a fast 7-15 day delivery timeline.

Frequently Asked Questions
Q: What makes the "pancake coil" design advantageous?
A: Unlike traditional straight lengths or large-diameter coils, the flat-wound pancake coil saves significant space, is easier to transport, and allows for smoother uncoiling and installation with less risk of kinking, reducing on-site labor time.
Q: Why is the C12200 (TP2) copper material important?
A: C12200 is a phosphorus deoxidized, non-arsenical copper. This composition provides excellent resistance to oxidation and "green rot" corrosion, superior weldability and brazability, and high ductility for easy bending and flaring without cracking.
Q: The product mentions the tubes are "cleaned and closed at extremities." Why is this necessary?
A: This is a critical quality control step. It ensures no moisture, dirt, or oxides are inside the tube during storage and transit. This preserves system purity, prevents performance loss, and eliminates the need for additional cleaning before installation, protecting compressors from damage.
Q: Is the optional insulation effective?
A: Yes. The closed-cell polyethylene foam insulation is highly efficient (thermal conductivity ≤0.033 W/mK), minimizing unwanted heat gain/loss on refrigerant lines. This improves system energy efficiency, prevents condensation ("sweating"), and has fire-retardant certifications for safety.
Q: Can I order sizes not listed in the standard specifications?
A: Absolutely. A key feature of our service is full customization. We can produce tubes with outside diameters from 3mm to 40mm and various wall thicknesses to meet your specific engineering and design requirements.
