Embodiment 1
[0051] Figure 1 shows a schematic diagram of the implementation structure of the present invention 1. (The outer layer of the composite pipe and the pipe connectors in Example 1 are both non-crosslinked high temperature resistant polyethylene DOWLEX*2344E). There are sockets 2 and 3 at both ends of the non-cross-linked high-temperature-resistant polyethylene pipe connector 1 . Composite pipes 4 and 5 are composed of silane cross-linked ethylene inner layer 6 and non-cross-linked high-temperature-resistant polyethylene outer layer 7, respectively, and respectively stretched into the sockets 2 and 3 of the pipe connectors using non-cross-linked high-temperature-resistant polyethylene. The characteristics of good welding performance are connected as a pipe network 8 by hot-melt welding. The nominal diameter of the pipe connectors and composite pipes is between Φ16 and Φ50, and the connected pipe network is most suitable for the indoor hot water heating pipe network in the northe...
Embodiment 2
[0053] Fig. 2 has provided the figure of embodiment 2 of the present invention. Embodiment 2 is basically the same as Embodiment 1, except that the non-crosslinked high-temperature-resistant polyethylene DOWLEX*2344E pipe connector 9 has a connecting flange 10 with a connecting through hole 79 on one end.
Embodiment 3
[0055] Fig. 3 has provided the figure of embodiment 3 of the present invention. Embodiment 3 is basically the same as Embodiment 1, except that the non-crosslinked high-temperature-resistant polyethylene pipe connector 11 is in the form of a 90° elbow.
