Key Specification

Inner spiral copper tube is the copper tube with smooth outer surface, and its inner surface has spiral of certain number and normality. Since the increase of the inner surface area of the copper coil tube, its heat conduction is improved by 30%-40%. As the global energy crisis and the implementation of admittance system for domestic energy-efficiency air-conditioner, the inner spiral copper tube will be widely used in the air-conditioning and refrigerating industry. Our inner spiral copper tube is characterized by superior quality, complete specification, moderate price and abundance product and it occupies it place in the competition of inner spiral copper tube market and enjoys good reputation in the market.
