If the PE tube is cut or damaged, the following repair methods can be taken:
Plug and socket fuse joint
If the damage range of the pipeline is small, the plug and socket fusion pipe joint method can be used. Cut off the damaged part of the pipeline, and then connect it to the electric fusion sleeve.
Docking connection
If the damage is extensive, cut off the damaged pipe section and replace the PE water supply pipe with a new one. The interfaces can be hot welded, flanged or fused. The final welded joint must be connected with a frit or flange.
Electrothermic fittings and clamps
If the PE pipe only appears small holes, sand holes, then repair with pipe fittings and pipe clamps. This method is relatively simple and fast, but the service life is short, generally 2 to 3 years.
The docking machine connects the two flange heads
Another treatment method that does not require the excavation of the pipe. It is to use the docking machine to butt the two flange heads, and the middle becomes a plastic expansion joint. This method is less affected by plastic expansion, the cost is small, and the service life is long. However, it is necessary to excavate a relatively large working face to put the docking machine in.
The electric hot melt welding machine processes the electric hot melt pipe fittings and a section of pipe fittings
This method has higher processing costs, but its service life will be longer.
If the cracking of the PE pipe is large, then the damaged part needs to be cut off. Re-weld the new PE pipe section. The above information is for reference only, it is recommended to consult professional maintenance personnel to obtain more accurate information.
