When the floor heating pipe wall is broken during decoration, it can only be hot melted. Only PERT floor heating pipe/PB pipe can be hot-melted, PEX pipe does not have hot-melting conditions due to the characteristics of the material itself. Some precautions when the floor heating pipe is hot-melted: First, before hot-melting, the pipe at the leak point should be cut vertically with a professional pipe cutter. , the incision must be smooth, and the burrs must be removed before hot melting; second, before the floor heating pipe is hot melted, use a dry cloth to wipe the inner and outer walls of the floor heating pipe; Make a hot-melt switch on the pipe fittings of the damaged pipe, and equip a hot-melt machine, and then heat it up with electricity; fourth, use a soft pencil first, and then use a hard pencil to draw a line on the hot-melt end of the pipe according to the required length; fifth, wait for After heating for a specified time, quickly remove the pipe and pipe fittings from the heating jacket and the heating head at the same time, and quickly insert the pipe into the specified depth of the pipe fitting without rotation, so that a uniform flange is formed at the joint, and the hot-melt joint is corrected. But it cannot be rotated. Keep the pipe fittings and pipes at an angle of 180 degrees; sixth, after reaching the specified time, carry out a pressure test, and it can be used without pressure relief. Thermal fusion of floor heating pipes requires a certain amount of experience and technology. Improper operation may result in failure.
