Embodiment Construction
[0022] see Figure 1-4 , an embodiment provided by the present invention: a fire-resistant and flame-retardant PVC pipe, including a PVC pipe 1, a connector a4 and a connector b5, characterized in that: the inner wall of the PVC pipe 1 is fixed with a metal mesh 3, and the metal Net 4 can improve the toughness of PVC pipe material 1, increase the compressive resistance of PVC pipe material 1, simultaneously PVC pipe material is a kind of new non-metallic pipe, can't detect its concrete position with existing metal pipeline detection equipment, and pipeline burying construction time is in The pipe needs to be buried with a wire to detect the position of the PVC pipe, and the metal mesh 4 can effectively allow the metal pipe detection equipment to detect the position of the PVC pipe 1, which is convenient for the staff to repair the pipe and improves the work efficiency of the staff. The inside of the PVC pipe 1 is provided with a flame-retardant insulation layer 2, the flame-re...
