Copper Tubes

Rajco Metal Industries offer Copper Tubes. These are used in DHP grade for a vide spectrum of the heating, ventilating, air-conditioning and refrigeration (AC&R), medical gas and cooling industry. These tubes are made from phosphorous deoxidised 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 B251 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 a meticulously clean, mirror-like inner surface and also to suit the new refrigeration gases like R 134 A, R-600 or R-410, and refrigeration lubricants like ester oil. These tubes are bright annealed, having uniform grain size, controlled hardness, elongation and tensile strength. These are readily bent, manipulated, soldered or brazed. The sizes manufactured range from 1 5/8" OD to 1/8" OD and in thickness from 10 to 30 SWG. Tubes can be supplied in 50 feet or 15 metres coil form or in straight length as per client requirements.
