ASTM B280 Standard Specification for Seamless Copper Tube for Air Conditioning and Refrigeration Field Service
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.
GENERAL SPECIFICATIONS:
Cleanliness: Bore quality meets the 0.038g/m ASTM B280 specified limit
Material: C12200, Cu 99.9% min, P 0.015 – 0.040%
Mechanical Properties : Tensile Strength: 290 MPa (min) | Elongation: 3% | Hardness: >100 HV
Temper: Hard Drawn
Packaging: Bore internally cleaned and capped
Bending: Not suitable for bending
Length: Manufactured in 10ft lengths, other lengths available on request
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:

QUALITY CONTROL
1. Incoming Raw Material Inspection
2. Raw Material Segregation to avoid steel grade mix-up
3. Heating and Hammering End for Cold Drawing
4. Cold Drawing and Cold Rolling, on line inspection
5. Heat Treatment, +A, +SRA, +LC, +N, Q+T
6. Straightening-Cutting to specified length-Finished Measuring Inspection
7. Machanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact, Mictrostruture etc
8. Packing and Stocking
100% of our steel tubes are dimensionally checked
100% of our steel tubes are visually checked to assure they have a perfect surface condition and no surface defects.
100% eddy current test and ultrosonic test to eliminate longitudinal and transversal defects
