Product Introduction

    Application:Air Conditioning & Refrigeration Industry

    Inner Grooved copper tube(IGT) is to improve the heat transfer characteristics of tube, the inner surface of tube is provided with spirally running grooves.Due to the increase of the internal surface area of the internally threaded copper tube, its thermal conductivity is 20 to 30% higher than that of the bare tube.With the world energy shortage and the implementation of the domestic energy efficiency ratio air conditioning access system, internally threaded copper pipes will be widely used in the air conditioning and refrigeration industry.
