1. Use a self-adjusting hot-melt welding machine to weld the pipes and fittings together at a temperature of 260°C. Connect the machine to the power (220V), when the green light flashes, it indicates that the welding temperature has been reached and start to work; if the ambient temperature is lower than 5℃, the heating time will be extended by 50%.
2. Due to the light weight and flexibility of the material, all welding must be performed on the workbench. Based on this advantage, man-hours can be saved.
3. Sometimes it is necessary to make certain connections in the wall. It is necessary to note that there is enough operating space at this joint location to allow accurate operation.
Use special scissors to cut the pipe, the cut should be smooth and free of burrs
Clean the welding parts of pipes and fittings to avoid damage to the quality of joints by sand, dust, etc.
Use the heating head that matches the size of the pipe to be welded to assemble the fuser, and heat it to 260°C
Mark the weld depth on the pipe with a marker
At the same time, insert the pipes and fittings into the fusion splicer and heat them for the specified time
After heating, push the pipes and fittings vertically and maintain them for more than 5 seconds, and do not use excessive force to prevent bending.
But be careful when welding, do not shake left and right, and the time should not be too long. The specifications of pipes and fittings should be unified. In addition, the welding equipment must have a constant temperature control. If the temperature is too high, the welding is impervious, and it is easy to leak water. If the temperature is too low, the welding speed is slow, and it is time-consuming and labor-intensive.
PPR water pipes can also be connected by hot-melt sockets. The pipes and pipe fittings are completely integrated, and the strength of the joints even exceeds the strength of the pipe body. As long as the construction is properly done, the pressure test after completion is extremely reliable
