1. Construction preparation: check the matching degree between the quality and specifications of pipes and fittings, and prepare normal hot melt tools.
2. Pipeline cutting: cut with special tools to ensure that the incision is flat and vertical without burrs, and the length is measured.
3. Pipe fitting treatment: clean and dry pipe fittings, check no defects.
4. Heating operation: set the temperature and time of the hot melt tool according to the material, and control the insertion depth.
5. Connection process: after heating, no rotation straight line is inserted to the marked depth, and the pipe fittings are not moved when the pressure is cooled.
6. Quality inspection: appearance check welding ring, size check slope, etc., pressure test check seal pressure, unqualified rework.
