Fangsheng PE-RT II Hot Melt Socket Welding Process
Author:
hot melt socket welding basic principle:
The principle of socket hot melt connection
1. The outer surface of the pipe and the inner surface of the pipe are heated by the welding head on the heating plate.
2. After heating for a certain period of time, the outer surface of the pipe and the inner surface of the pipe are melted.
3. The pipe is inserted into the pipe socket to a certain depth, and the polymer melt is fused together to form a complete whole.
The entire welding process does not require any auxiliary materials.
Key Control Points of Hot-melt Socket Welding
1. Control of welding temperature
2. Ambient temperature (high temperature or low temperature), wind speed, whether there is dust
3. Dimensional tolerance of pipe fittings
4. Whether the welding surface is clean
hot melt socket welding basic process:
Preparation: (man, machine, material, method, ring)
1. Personnel shall be certified and wear protective equipment, heat-insulating gloves and protective shoes.
2. The heating equipment works normally (heating, heat preservation), select the correct welding head, check for damage and cleaning, and ensure timing.
3. The end faces of pipe fittings shall be neat and free of burrs, and the inner and outer surfaces shall be cleaned.
4. Welding parameters can be consulted at any time.
5. Ensure a suitable ambient temperature (5-40 degrees) and no extreme weather effects from heavy rain and snow.
6. When the hot melt socket welding machine reaches the set temperature, mark the insertion depth and heat it at the same time.
7. Keep the specified time to ensure that the welding surface of the pipe and pipe fittings is melted and pulled out at the same time.
8. Quickly insert the pipe into the pipe socket and keep it for the specified time.
9. Cooling the prescribed time.
Check hot-melt flanging:
1. Check whether the internal and external hot-melt flanging is uniform.
2. Check whether there is obvious false welding.
3. Clean up the site: clean up the equipment, heating plate and welding head, clean up the work site.
