Specifications of RAJCO AC & R Copper Tube
Rajco air conditioning & refrigeration copper tubes are manufactured to suit various specifications, prominent amongst these are the ASTM B-68, ASTM B-75, BS-2871, EN-1057, ASTM B-280 and JIS H-3300. Tubes are also manufactured to suit internal client specifications. We are proud to supply to a wide range of refrigeration and air conditioning requirements in hard, half hard, quarter hard, soft or light annealed condition.

Rajco AC & R copper tubes are made from phosphorous deoxidized copper (DHP grade) alloy C-106 or UNS No. C-12200 with minimum copper purity of 99.9% and phosphorous purity of 0.015% to 0.040% with strict dimensional tolerances as per ASTM B-251 to ensure the highest standards and guaranteed performance. The internal bore cleanliness meets the requirement of the residue test as specified by the codes to give you a meticulously clean, mirror-like inner surface and also to suit the new refrigeration gases like R 134A, R-600 or R-410 & refrigeration lubricants like Ester Oil. The tube integrity is well defined by the fact that all tubes meet the standards of ASTM E 243 & are eddy current tested to ensure that a defect free and flawless tube is supplied to the customer.

Rajco's AC & R tubes are bright annealed, having uniform grain size, controlled hardness, elongation & tensile strength. Tubes can be readily bent, manipulated, soldered or brazed. Rajco's refrigeration quality tubes are not only exported but are also contributing to import substitution in India, relied upon by Daewoo, Voltas, Blue Star, Matsushita and O’General. The sizes manufactured range from 1/8” OD to 4 ” OD and in thickness from 10 to 29 SWG. Tubes can be supplied in 50 feet or 15/24 metres coil form or in straight length as per client requirements.
