Wall thickness
Industry catalog reference range: 0.70–1.50 mm for some pancake coil ranges. Other wall thicknesses can be requested. The actual OD × wall combination must be confirmed for the chosen standard and application.
Copper pancake coils
Copper tube in compact pancake coils for air-conditioning, refrigeration piping and fabrication inquiries. Share your outside diameter, wall thickness, coil length and delivery requirements for a specification-based quotation.

01 / DIMENSIONS & TOLERANCES
Start with the right dimensions.
These outside diameters are common industry inquiry references. They are not a confirmed stock list; request the wall thickness and length that your application requires.
| Outside diameter · inch | Outside diameter · mm |
|---|---|
| 1/4″ | 6.35 mm |
| 5/16″ | 7.94 mm |
| 3/8″ | 9.52 mm |
| 1/2″ | 12.70 mm |
| 5/8″ | 15.88 mm |
| 3/4″ | 19.05 mm |
| 7/8″ | 22.22 mm |
Length per coil
Common inquiry references include 15 m, 30 m and 50 ft (15.24 m). State the exact unit: 15 m and 50 ft are different lengths. Specify any required length tolerance.
Specify the acceptance criteria
- OD & wall: identify the standard and edition, nominal dimensions, permitted OD variation and minimum acceptable wall thickness.
- Coil geometry: state the coil inside / outside diameter, packing height and any ovality or end-straightness criteria needed for your equipment.
- Length & inspection: agree the permitted length variation, sampling method, measuring method and any tighter drawing requirements before ordering.
Reference specifications for inquiry only. Available dimensions, manufacturing tolerances and compliance documentation are confirmed in the quotation. Pressure or refrigerant suitability must be checked against the complete system requirements.
02 / GRADE, TEMPER & STANDARD
- Grade requests: C12200 or Cu-DHP are common ACR purchasing terms. If your drawing calls for TP2 or CW024A, state that designation and its governing standard explicitly; equivalence is subject to review.
- Temper: specify soft / annealed tube for coiled supply where required. Use O60 or R220 only with its corresponding standard and agreed material condition.
- Standard: indicate ASTM B280 for ACR field-service tube or EN 12735-1 for relevant refrigeration / air-conditioning piping. Include the edition and any additional project requirements.
03 / QUANTITY, PACKING & DESTINATION
- Quantity: 250 kg, 500 kg or 1 metric ton MOQ, depending on specification. State the quantity per size and whether mixed sizes are required.
- Packing: discuss end caps, protective bags, individual cartons, coil separation, pallet dimensions and any destination-specific wood packaging requirements.
- Delivery: provide the destination country, postal code or port, requested trade terms, shipping marks and preferred shipment date for a complete quotation.
04 / INSPECTION & DOCUMENTS
- Material & dimensions: request chemical composition, agreed mechanical-property evidence, OD / wall / length inspection and batch identification as needed.
- ACR cleanliness: specify internal cleanliness, dry condition and sealed ends. Eddy-current, pressure or leak testing requirements must be agreed against the applicable standard and order.
- Documents: identify any mill test report, certificate of conformity, packing list, invoice or certificate of origin needed. EN 10204 document types and third-party inspection are subject to confirmation; no certification is implied.

Before you request a quotation
Is the MOQ always 250 kg?+
No. The applicable minimum may be 250 kg, 500 kg or 1 metric ton depending on the size, wall thickness and packing. We confirm it for each specification.
Are 15 m and 50 ft the same coil length?+
No. 50 ft equals 15.24 m. State the exact nominal length and acceptable tolerance in your inquiry.
Does listing a standard confirm product certification?+
No. These standards help define the inquiry. The quotation and supplied documentation must confirm the exact grade, temper, standard and inspection requirements.
