[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0018] like Figures 1 to 4 In the embodiment of the new PE gas pipe of the utility model shown, the new PE gas pipe includes two PE pipe bodies 1 connected by fusion, and a protective pipe 2 is sleeved on the two PE pipe bodies 1. A gap is left between the protective pipe 2 and the connection between the two PE pipe bodies 1, and a glue injection hole 3 is opened on the protective pipe 2, which is connected to the gap. A fastening kit 4 is provided on the protective pipe 2, and a polyethylene adhesive tape 5 is provided on the fastening kit 4. When the two PE pipe bodies 1 are connected by fusion, the protective pipe 2 and the fastening kit 4 can protect the fusion connection of the two PE pipe bodies 1, and to a certain extent, avoid bending at the fusion connection of the two PE pipe bodies 1, thereby avoiding the problem of unreliable connection and fixation of the two PE gas pipes. By injecting anti-corrosion glue into the gap through the glue injection hole 3, an anti-corrosion effect is played, and a better fixing effect is also achieved. Moreover, the setting of the polyethylene adhesive tape 5 further plays an anti-corrosion effect at the connection.

[0019] In one embodiment of the present application, preferably, the PE pipe body 1 includes an inner layer 101, an outer layer 102 and a steel mesh 103, and the steel mesh 103 is arranged between the inner layer 101 and the outer layer 102. The composite multi-layer structure of the PE pipe body 1 can make it more stable, and the setting of the steel mesh 103 can play a better protective role to prevent the PE pipe body 1 from rupturing or being bitten by mice.

[0020] In one embodiment of the present application, preferably, the inner layer 101 and the outer layer 102 are both made of polyethylene plastic.

[0021] In one embodiment of the present application, preferably, the protective tube 2 is sleeved on the outer layer 102, and the fastening kit 4 includes a fastening sleeve 401 and a screw tube 402. The number of the screw tubes 402 is two, and the two sides of the fastening sleeve 401 are constricted. Both sides of the fastening sleeve 401 are provided with multiple makeshift grooves, and the fastening sleeve 401 can be deformed. The two screw tubes 402 are respectively threadedly connected to the two sides of the fastening sleeve 401, and the fastening sleeve 401 is sleeved on the protective tube 2. By rotating the screw tube 402, the two sides of the fastening sleeve 401 can be buckled inward, and force is applied to the protective tube 2, thereby increasing the friction between the protective tube 2 and the PE tube body 1, thereby preventing the protective tube 2 and the PE tube body 1 from loosening.

[0022] In one embodiment of the present application, preferably, both sides of the polyethylene adhesive tape 5 are respectively bonded to the opposite ends of the two PE pipe bodies 1, thereby playing an anti-corrosion role.

[0023] In one embodiment of the present application, preferably, a through hole is opened on the fastening sleeve 401, a plug is provided in the through hole, the through hole is connected with the glue injection hole 3, and the anti-corrosion glue can be injected by opening the plug.

[0024] When the utility model is in use, after the two PE pipe bodies 1 are butt-jointed by fusion, the fusion joint of the two PE pipe bodies 1 can be protected by the protective pipe 2 and the fastening kit 4, and bending of the fusion joint of the two PE pipe bodies 1 can be avoided to a certain extent, thereby avoiding the problem of unreliable connection and fixation of the two PE gas pipes. By rotating the screw 402, the two sides of the fastening sleeve 401 can be buckled inward, and force is applied to the protective pipe 2, so that the friction between the protective pipe 2 and the PE pipe body 1 becomes larger, thereby avoiding loosening between the protective pipe 2 and the PE pipe body 1. By opening the stopcock, anti-corrosion glue is poured into the gap through the glue injection hole 3, thereby playing an anti-corrosion role. By setting the polyethylene adhesive tape 5, a further anti-corrosion effect is played at the connection.
