Beschreibung
Zusammenfassung:	The utility model relates to a plastic coated copper pipe, which is composed of a copper pipe 2 of an inner layer and a plastic pipe 3 of an outer layer. A heat insulating slot 4 is arranged between the copper pipe of the inner layer and the plastic pipe of the outer layer. The utility model is characterized in that the section of the heat insulating slot is a trapezoidal structure. The utility model has reasonable structural design. The heat insulating slot is designed into the trapezoidal section, the contact area of the copper pipes and the heat insulating slot is effectively enlarged, the quality of the outer surface is improved, the deformation resisting performance is increased and the heat insulating performance can be guaranteed. The utility model has the characteristics of beautiful appearance, convenient installation, sanitation, cleanness, long service life, etc.
