HARD DRAWN COPPER TUBE

METCO IMPEX is one of the leading and renowned manufacturer and exporter of Hard Drawn Copper Tube with a complete range of outer diameter and wall thickness combinations, engineered to exact specifications to meet the highest standards of performance as required by the refrigeration and air conditioning industry . In METCO IMPEX copper tubes are available in a variety of tempers to suit the intended applications. It is supply to special requirements as to dimensional tolerances, finish and tempers for use in condensers and heat exchangers. The Copper Heat Exchanger tubes are generally supplied in straight length in even annealed half hard temper. We manufacture Hard Drawn Copper Tube which are compatible to transfer heat in a wide variety of operating conditions and to resist corrosion for the longest period of time possible under the harshest operating conditions. .

Our Hard Drawn Copper Tube is used in general engineering purpose mainly because of its thermal conductivity, electrical conductivity, malleability, strength and corrosion resistance. Our manufacturing range of copper tubes possesses roundness, straightness, uniformity of the wall thickness, smooth inner and outer surface to make it the ideal choice for general engineering applications. METCO IMPEX manufacture specially cleaned and degreased  Hard Drawn Copper Tube suitable for use in medical and industrial gas applications.

These tubes are with ASTM B 819 and are rigorously tested to make sure they are suitable for the exacting requirements of critical medical and gas application industry.
