The pressure standard for PPR water pipes is 8 to 12.5 kg, that is, 0.8 to 1.25 mpa. The specific pressure depends on the wall thickness of the pipe. If the ppr water pipe is 25×2.3mm, or 32×3.0mm, the pressure of 1.25mpa is required at this time. The ppr water pipe is 25×2.3mm, or 25×2.8mm, and the pressure of 1.60mpa is required at this time.
The PPR water pipe is pressed for one hour. If the pressure value remains unchanged, it means that the installation is qualified and there is no problem, and the next step can be carried out. Otherwise, it needs to be repaired in time, so as not to increase the difficulty of the later work.
