Wuxi Yansheng Technology Co., Ltd., established in 2017 with a factory spanning 1,000–3,000 square meters, is proud to offer the ASTM B280 Certified C12200 Thin Wall Copper Pancake Coil — a premium solution specifically designed for professional refrigerator installation and HVAC applications. As a manufacturer with an annual export value between US$50 million and US$100 million, we combine rigorous quality control with competitive pricing. This copper coil is engineered to deliver superior thermal conductivity, corrosion resistance, and flexibility, making it the ideal choice for both new installations and replacement projects. Our commitment to international standards ensures that every meter meets the strict ASTM B280 specification, giving you confidence in long-term performance.
Product Overview: The C12200 thin wall pancake coil features a high-purity copper composition (99.9% copper) that guarantees excellent heat transfer and durability. Its thin wall design reduces weight and eases bending during installation, while the pancake form factor allows for compact storage and easy handling. Each coil is meticulously manufactured in our ISO9001-certified facility, and we offer multiple length and diameter options to suit diverse refrigeration requirements.
Key Features & Benefits
- ASTM B280 Certified: Full compliance with the international standard for seamless copper tube used in air conditioning, refrigeration, and other HVAC systems. Ensures dimensional accuracy, cleanliness, and pressure rating.
- C12200 Copper Material: High-purity phosphorus deoxidized copper (C12200) offers exceptional resistance to hydrogen embrittlement and corrosion, extending service life even in demanding environments.
- Thin Wall Design: Lightweight and flexible, the thin wall (0.032”–0.049”) reduces installation effort while maintaining reliable burst strength. Ideal for tight spaces in refrigerator back panels.
- Pancake Coil Form: Planar wound coil eliminates kinking and tangling, streamlining the installation process. The continuous length minimizes joints and potential leak points.
- Clean & Deburred: Each coil is thoroughly cleaned and deburred at both ends, preventing debris from entering the refrigerant circuit and ensuring a leak-free connection.
- Bright Surface Finish: A bright, oxide-free surface enhances aesthetic appeal and provides a clean base for brazing or soldering.
- Customizable Lengths: Available in standard lengths of 50 ft, 100 ft, as well as custom spools per customer request (typically 50, 100, 200, or 500 ft).
- Multiple Outer Diameters: Choose from 1/4", 3/8", 1/2" or other common sizes to match your refrigerator’s installation ports.

Why Choose Our Copper Pancake Coil? Our manufacturing process ensures consistent wall thickness, roundness, and cleanliness — critical factors for trouble-free brazing and long-term leak prevention. The thin wall construction reduces material consumption without sacrificing mechanical integrity, offering cost savings for large-scale installations. Compared to standard straight tubes, the pancake coil eliminates the need for multiple joints, enhancing system reliability. Furthermore, the C12200 grade provides superior formability, allowing easy bending by hand or with simple tools.
Applications: Specifically tailored for refrigerator and freezer installation, our copper coil is also widely used in air conditioning units, heat pump systems, and commercial refrigeration equipment. It connects compressors to condensers and evaporators, delivering refrigerant with minimal pressure drop. The thin wall design is particularly beneficial in retrofit projects where existing space is limited.

Frequently Asked Questions (FAQ)
-
What does ASTM B280 certification mean for this copper coil?
ASTM B280 is the standard specification for seamless copper tube used in air conditioning and refrigeration systems. It guarantees the tube meets precise dimensional tolerances, cleanliness, and mechanical properties such as burst pressure and elongation. Our coils are tested to comply with this standard. -
Can I use this pancake coil for a refrigerator ice maker or water line?
This coil is specifically designed for refrigerant gases (e.g., R-410A, R-134a) and HVAC applications. For potable water lines, please consult our technical team, as the thin wall may not be suitable for high-pressure water systems. Refrigerant use is recommended. -
What is the maximum operating pressure for the thin wall coil?
The pressure rating depends on the outer diameter and wall thickness. For a 1/4" OD with 0.032" wall, the typical working pressure is around 650 psi (4480 kPa) at room temperature. Always refer to the ASTM B280 pressure table for specific values. Our team can provide detailed data upon request. -
Does the coil come with fittings or connectors?
The coil is supplied as a bare tube without fittings. However, we can provide custom end preparation (e.g., swaging, flaring) upon special order. Standard ends are deburred and ready for brazing. -
How long is the typical delivery time for bulk orders?
For standard coils (50 ft or 100 ft), we usually ship within 10–15 working days after order confirmation. Custom lengths may require 15–25 working days. We ship from Tianjin, Shanghai, Qingdao, or Ningbo ports. -
Can I get a sample before placing a large order?
Yes, we offer sample coils (e.g., 5–10 ft pieces) for qualification. Shipping costs apply, but the sample fee is typically waived for potential bulk buyers. Contact our sales team to arrange. -
Is this coil suitable for outdoor condenser units?
C12200 copper has good corrosion resistance, but in highly corrosive environments (coastal or industrial), we recommend additional protective coating. The bare coil is intended for indoor or sheltered installations. For outdoor use, consider our optional epoxy-coated variant. -
What packaging method protects the coil during shipping?
Each pancake coil is first wrapped in a sealed plastic bag to prevent moisture and dust, then placed in a sturdy carton, and finally packed on a plywood pallet with corner protectors and straps. This ensures the coil arrives undamaged.
