The outside of the PE pipe port should be chamfered, the angle should not be less than 30°C, and the length of the groove on the surface of the pipe should not be greater than 4mm; The dirt on the connecting surface of the pipe fittings should be cleaned with a clean cotton cloth; the hot-melt socket connection of the pipe with a nominal outer diameter greater than or equal to 63mm should be the hot-melt socket connection of the mechanical device, and the two corresponding pieces to be connected should be straightened so that on the same axis. For hot-melt connection of pipes with a nominal outer diameter less than 63mm, manual hot-melt socket connection can be used with the cooperation of a full-circle tool; the outer surface of the PE pipe socket and the inner surface of the PE pipe fitting socket should be heated with a hot-melt socket-type heating tool; after the heating is completed After that, the parts to be connected should be quickly separated from the socket connection heating tool, and the uniformity of melting of the heating surface of the connecting parts and whether there is any damage should be checked. Then, insert the PE pipe into the socket of the pipe fitting with a uniform external force to the position where the pipe is inserted into the length mark, so that the end of the socket forms a uniform flange.
