SPECIFICATION: COPPER TUBES CONFORMING TO ASTM B: 280/B 68/B 75/ JIS H 3300
The Straight tubes will be supplied in Hard Drawn condition and Coils in soft annealed condition
The Chemical composition will confirm to grade C 12200 designated as DHP Grade “Phosphorus Deoxidized High Residual Copper” grade having min. Copper percent 99.9% with Phosphorus percent of 0.15 to 0.40%.
The Copper tubes will have the following physical / mechanical properties
Tensile Strength |
250 Mpa Minimum |
Elongation |
Not Required |
Hardness |
90 HV5 Minimum |
Grain size |
Not required |
Expansion |
Not Required |
All copper tubes will be 100% eddy current tested as per ASTM E:243 and no tubes will be supplied without eddy current testing.
Dimensional tolerance will be strictly as per the allowed tolerance of the specification for average diameter and wall thickness tolerance.
The sizes of Copper Tube(s) are specified as follows:

The tests will be conducted on each lot of Copper tubes and Test Certificate will be provided with material. The Test Certificate will be provided as per the specification only. No Copper Tube will be dispatched without valid test certificate and will not be acceptable without the Test Certificate.
All Copper Tubes will be supplied with clean inside finish and will be supplied as per required length specified in the PO. The contamination level allowed will be max 0.038 gm/mm2
All Copper Tubes will be supplied with end Caps at both ends
The Copper Tubes must be packed & wrapped in shrink wrapping bags to protect them from any atmospheric degradation/ contamination
JANYA copper tubes are compiled to European Directive on ROHS (Lead/ Mercury/Chromium – within 1000ppm and Cadmium 100 ppm max), presence of these heavy elements above the permissible limit are hazardous to human life
Each JANYA Copper pipe will have Permanent markings on the surface of the pipe with Name of the Brand, Specification, Temper, Dimension and batch No
