Inner Grooved Copper Pipe

Inner Grooved Copper Pipe内螺纹铜管

Use:high thermal conductivity, widely used in air conditioning and refrigeration industry

State:Soft

Standard:GB/T20928 EN12735

Features


With the increase of internal surface area, the thermal conductivity of inner grooved copper tubes is 20%~30% higher than that of smooth tubes. Therefore, inner grooved copper tubes are widely used in the air conditioning and refrigeration industry
