Which saves 3 joints out of every 4 joints for VRF, package & Ductable Air Conditioning Piping Circuit for building projects as well as better comfort care, of every resident of India.
With continuous research and development taking place at MANDEV TUBES, we have been able to innovate and develop the ONE END EXPANDED COPPER TUBE WITH INNER BRAZING RING. The unique design helps eliminate a coupling cost, while joining the tubes. Not only it reduces costs by up-to 78% comparing to regular tube installation cost, it prevents leakage by 50% and also helps in saving 100% of your BRAZING COST.
Further as the tubes are of half hard temper, one can eliminate elbow cost, while joining the two tubes. Due to this uniqueness, it reduces costs by up-to 100% compared to regular installation and also prevents leakage by 100%. These tubes can be easily bent with the help of Mechanical bender.
Minimum Diameter: 3/18" (4.78mm) / Maximum Diameter: 41/4" (108mm)
Minimum Wall Thickness: 0.020” (0.5mm) / Maximum Wall Thickness: 0.098” (2.5mm)
Minimum Length: 2.0' (0.6 mtr) / Maximum Length: 19' (5.79 mtr)
Half-Hard
"Stress Relieved" one end expanded tubes are eddy current tested, RoHS Compliant, CFC- Free refrigeration compatible and with 1000 residue content below 0.20 mg/dm 2.
One end expanded tubes with brazing ring are supplied with a commercial saw cut with minimum burs as standard on one end, mechanically expanded & debarred on the other end at added cost.
