ASTM B280 C12200 Seamless Copper Tube for conditioning
This specification covers the requirements for seamless UNS C10200, C12000, or C12200 copper alloy tubes used for connection, repairs, or alternations of field air conditioning or refrigeration units. Materials in the form of billets, bars, or tubes should be used to produce a homogeneous uniform wrought structure by either hot or cold working. Each tube should be cold drawn to the finished size and wall thickness. Coiled lengths with soft annealed tempers should be bright annealed after coiling then dehydrated and either capped, plugged, crimped, or otherwise closed at both ends. Straight lengths with hard drawn tempers should be cleaned and either capped, plugged, or otherwise closed at both ends.

Scope
1.1 This specification establishes the requirements for seamless copper tube intended for use in the connection, repairs, or alternations of air conditioning or refrigeration units in the field.
NOTE 1: Fittings used for soldered or brazed connections in air conditioning and refrigeration systems are described in ASME Standard B16.22.
NOTE 2: The assembly of copper tubular systems by soldering is described in Practice B828.
NOTE 3: Solders for joining copper tubular systems are described in Specification B32. The requirements for acceptable fluxes for these systems are described in Specification B813.
1.2 The tube shall be produced from the following coppers, and the manufacturer has the option to supply any one of them, unless otherwise specified:
Copper
UNS No. | Previously Used
Designation | Description |
| C10200 | OF | Oxygen free without
