1. Directly measure the diameter of the pipe fitting;
2. The actual measurement method is calculated according to the field used. If the PPR tube is not the whole root, it is calculated as the whole root. In addition, it is necessary to master certain aspects of ppr welding
Experience is good, otherwise it is easy to make mistakes in the splicing process.
Precautions:
1) Before construction, check whether the two ends of each pipe are damaged to prevent damage to the pipe during transportation. If there is damage or uncertainty, the port should be deducted when the pipe is installed.
4-5cm, do not use hammers or heavy objects to hit the water pipes to prevent pipe bursts and relatively increase the service life.
2) The PPR tube hot-melting machine has red and green indicator lights. The red light represents heating and the green light represents constant temperature. It cannot be used when No. 1 reaches the green light. It can only be used when No. 2 reaches the green light.
The temperature is between 260°C and 280°C. If the temperature is lower or higher, the joint cannot be completely fused, leaving a hidden danger of water seepage.
3) When cutting PPR pipes, the end face must be perpendicular to the pipe axis, and special pipe cutters should be used for pipe cutting.
