ASTM B280 Pacake Coil from East Jin International Co., Ltd. is seamless copper tubing drawn from electrolytic copper with a minimum purity of 99.99%, conforming to ASTM B280 for air conditioning and refrigeration service. The coil format packages continuous lengths for efficient handling on HVAC job sites and in production lines. South Korean copper processing maintains tight dimensional control and consistent temper throughout each coil, which matters for brazed joint integrity and long-term refrigerant containment.
The tube wall thickness and outer diameter vary by application need, with common refrigeration sizes ranging from 1/4 inch to 7/8 inch nominal. ASTM B280 specifies annealed temper for field bending and flaring, though drawn temper is available for straight-line applications. The 99.99% electrolytic grade offers thermal conductivity of approximately 391 W/m·K at 20°C, a standard value for this copper purity level. Corrosion resistance derives from the inherent nobility of the material rather than any coating, making it compatible with common refrigerants including R-410A and R-32.
HVAC contractors, refrigeration equipment manufacturers, and wholesale distributors serving the MEP sector are the primary buyers. The coil format reduces scrap and eliminates the need for on-site straightening of stick copper. Buyers should confirm exact outer diameter, wall thickness, and coil weight with East Jin International before ordering, as these determine compatibility with existing brazing procedures and handling equipment. The supplier lists FOB and CIF terms as available, though specific Incoterms and any minimum order quantities require direct confirmation.

Before ordering ASTM B280 Pacake Coil from East Jin International, verify the exact outer diameter, wall thickness, and temper required for your brazing or mechanical joining system. Request a current mill test report showing chemical composition within ASTM B280 limits and dimensional inspection data. Confirm whether the supplier maintains inventory in South Korea or sources through a third-party mill, as this affects traceability and recourse in case of non-conformance. Given the zero recorded response rate, plan for multiple contact attempts and consider using alternative channels such as the company's registered business telephone or a local trade representative in Seoul.
Logistics planning requires confirmation of Incoterms beyond the FOB and CIF mentions in the source. For CIF shipments, clarify whether marine insurance is included and what coverage limits apply. Identify the export port, typically Busan or Incheon for South Korean metal products, and estimate transit time to your destination. Payment terms are unstated; common practice for first transactions with Korean suppliers involves 30% advance with letter of credit balance, though this varies by relationship and order volume. Request a proforma invoice specifying exact coil count, net and gross weight, and harmonised system code 7411.10 for copper tubes and pipes.
Quality assurance on arrival should include dimensional spot checks against ASTM B280 tolerances, visual inspection for coil deformation or transit damage, and verification of marking compliance (grade, temper, and manufacturer identification if required). Consider engaging a third-party inspection agency such as SGS or Bureau Veritas for pre-shipment inspection at the Korean port, particularly for first orders. Retain samples from each coil for future traceability. Documentation required for customs clearance typically includes commercial invoice, packing list, bill of lading, certificate of origin, and any applicable import licence for copper products in your jurisdiction.
