Connection method PP-R pipes and fittings for the general use of hot melt or fused connection, connect
the pipes and fittings while heating the critical melt into, and then the pipe immediately straight
insert fittings in good pipeline contact performance welding complete, the success rate high. But when
the weld should be careful not to shake around, time not too long. Pipe and fittings specifications to
unity. In addition, the welding equipment must be thermostatically controlled, high temperature welding
impermeable, easy to leak, the temperature is too low, the welding speed is slow, laborious and time
consuming.

The steps of welding:
1.Use special pipe cutter to cut the pipe, the cut should be smooth and free of burrs.
2.Clean the welding area of pipes and fittings, to avoid sand, dust and other damage to the joint quality.
3.And being welded pipe size with matching head assembly fuser heating, heated to 260 ℃.
4.Marked with a marker on the pipe welding depth.
5.While the pipe and pipe fittings into the welding device, the time required for heating.
6.After heating, the vertical pipe and fittings to promote and maintain more than 5 seconds,
not excessive force to prevent bending.
