ASTM B280 is the definitive standard for seamless copper tubing specifically designed for air conditioning and refrigeration (ACR) applications. This oxygen-free, nitrogen-charged copper tube is meticulously manufactured to be clean, dry, and capped to prevent contamination, ensuring the integrity and longevity of sensitive HVACR systems. Unlike standard water tube, ACR pipe is delivered ready for field service, offering superior brazability and corrosion resistance for critical refrigerant lines, HVAC line sets, and chiller systems. When failure is not an option, specify ASTM B280 for guaranteed performance and protection against costly compressor burnouts and system contamination.
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.
