1)wall thickness:3/8" thickness is 0.7mm,5/8"thickness is 0.8mm

2)Each end of copper pipe has copper screws and insulation nut

3)Pure copper matrial with good stretching resistance

4)Good quality insulation layer with plastic parts

5)Anti-UV,good heat resistance,low water absorption

6)Differnt length/Diameter/ wall thickness

For the heat preservation coated copper pipe adopted by double-tube air-conditioner coated copper pipe, the conventional thickness heat preservation tube can not have the functions of preserving heat and preventing dew. The super-thick heat preservative coated copper pipe made of WICPE for air conditioner doesn't need to be coated for heat preservation on construction site and its length can be cut freely. This not only reduces time and labor of the project, but also has the qualities of high efficiency, energy conservation, and environmental protection. It is a kind of air-conditioner piping material that can be used for both cooling and heating. This product satisfies the air-conditioner piping requirements for families or even the large scale commercial use in high buildings
