1. PPR pipes and fittings are connected by hot melt, but they cannot be threaded directly on the pipes and fittings. When connecting with metal pipes, flange connections can be used. When connecting with water heaters, pipe fittings with metal inserts must be used. ;
2. In the process of hot-melt connection, you must use reliable hot-melt equipment, which can ensure the quality of welding;
3. When using special scissors to cut PPR pipe vertically, ensure that the cut is kept flat and free of burrs;
4. The welding parts of PPR pipes and fittings must be clean to prevent sand and dust from damaging the quality of the joints;
5. When inserting in welding, the equipment must be heated according to the specified time for pipes and fittings;
