Socket Fusion Procedure

1. Preheat heating tool 260° C (500°F). Surface temperature can be checked with a Tempilstik.
2. Chamfer pipe ends (1-¼ NPS and larger sizes). One turn of chamfering tool should produce required chamfer. This procedure helps to center pipe into fitting.
3. Clean the pipe end with a clean rag.
4. Using the depth gauge, place cold ring on pipe to ensure pipe roundness and proper socket stab depth.
5. Push fitting on heater face and then push pipe on heater face keeping both in place for the prescribed heating cycle.
6. Heating Cycle Time - stop or sweep hand watch to be used with heating cycle beginning after fitting and pipe are fully inserted on heater face.
7. "Snap" the fitting from the tool briskly and the iron from pipe end. This avoids melt sticking to the tool.
8. "Stab" the fitting onto the pipe smoothly and straight. Do not twist or turn the pipe or fitting during or immediately after the "stab".
9. Hold together for time equal to "Heating Cycle Time".
10. Clean heater faces carefully. Do not damage heater face coating. Use non-metallic cleaning stick.

1. Check to see that heating tool surface temperature is 260° C (500°F).
2. Make a melt pattern of scrap piece of pipe using the heating cycle for the appropriate pipe size listed in the cold weather table.
3. If melt pattern is incomplete, try a longer 3-second cycle on another end of the pipe. Continue additional 3-second cycles until complete melt pattern is obtained. Use the Heat Cycle Time, determined by the number of additional 3-second heat cycles.
4. Cut and chamfer pipe end.
5. Using depth gauge, place two sets of cold rings on pipe; shim one set and clamp behind cold ring set by depth gauge.
6. Using cold weather heating cycle, follow normal joining procedures; heating cycle starts after fitting and pipe are fully inserted on heater face.

1. Melt bead must be pressed evenly against a minimun of 50% of the fitting face.
2. Pipe and fitting must be properly aligned.
3. Melt bead area must be free of gaps or voids.
