The inner-grooved copper tube is an ultrathin-wall red copper tube with high content of technology and internationally leading technology.Superhigh-precision thin-wall high-and-inner-grooved copper tubes are mainly applied to various refrigerating machines with the thermal transmission coefficient increase by 30%-40% against the conventional tubes and the coefficient of condensing heat exchange 8-10 times higher than those of plain tubes.The high-precision thin-wall high-and-inner-grooved copper tube production line was specified by the State Economic&Trade Commission, PRC as one of the projects of high-tech industrialization, Adoption of high-tech and proper advancee tech to renovate traditional enterprises and optimizing the structure of key products and technologies.
