Anotácia

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. The grain sizes, tensile properties, and eddy-current and cleanness test results should conform to the values listed herein.
