Socket Fusion Joint Step:(Use Socket Fusion Welding Machine)

(1)Check and measure

·Check the pipeand fittingsto seewhether theyare damaged, and make the incision smooth. ·Measure the depth of socket, mark on the pipe surface.

(2) Chamfer

·Chamfer the nozzle,the angle should be 3 0 ^ { \circ } , the length of surface groove should not exceed 2 . 0 \mathsf {mm }

(3) Clean and dry ·Clean and dry the pipe's spigot and the fittings' socket.

(4)Heat

·Push the end of the pipe and fitings, without turning, upto the welding depth into the welding machine, heat up the end of the pipe and fittings.

(5)Join and cool

·Pull out the pipe and fittings from the welding machine when the scheduled heating is over, insert the pipe's spigot into the fitings'socket evenly and swiftly.
