These copper tubes are manufacture using phosphorous di-oxidize 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%. The internal bore is tested on residue test as specified by the codes to provide a clean mirror like inner surface. These tubes also suits the new refrigeration gases like r 134 a, r-600 or r-410 and refrigeration lubricants like ester oil. All tubes meet the standards of ASTM e243 & are tested to ensure that a defect free and flawless end product.
These tubes are bright annealed, have uniform grain size and controlled hardness with elongation and high tensile strength. Our range of tubes can readily be bent, manipulated, soldered or brazed.
Our range of refrigeration tubes are not only exported but also used in India by well known companies like Hitachi, Daewoo, Voltas, Kirloskar Copeland, Electrolux, BPL Sanyo and Blue Star.
These specially cleaned copper tubes are used for medical gas lines. Also used for surgical vacuum systems, these tubes are resistant to corrosion and the inner surfaces are easily cleaned periodically with detergents when in use. The detergent is passed through the lines to purge and sterilize the lines. Our range of copper tubes and fittings are the only solution for supplying medical gases with proper safety and cleanliness requirements conforming to various specifications. Safety standards for copper and other positive pressure medical gases require the use of copper tubes with special cleanliness.
