PE pipe filling holes need to be determined according to the actual situation
①Temporary urgent repairs can be temporarily handled by the repair festival or the Hoop connection, but the maintenance time is generally within one year.
② The broken part can be cut off, the cuts at both ends are flat, the flat port is connected to the flange by hot melt, and the two sets of flanges are connected to the steel sheet.
③If the pipeline settlement is relatively serious and the damage area is relatively large, the loophole pipe should be cut at this time, and the short link link pipeline should be directly added with an electric fusion elbow or electric fusion.
④If the diameter of the pipe is small, you can cut the hole and use direct hot-melt connection (not commonly used).
