In order to prolong the service life of PPR water pipes, it is not only determined by its own quality, but also affected by construction factors. Therefore, in order to prolong the service life of PPR water pipes, the following points should be paid attention to.
1. Because of the material limitation of PPR pipe, its pressure resistance is not as pressure-resistant as that of metal pipe. Therefore, protection work should be done well during construction, and it should not be squeezed by strong external forces.
2. It is strictly forbidden to expose the PPR tube to the sun and place it in a lower temperature environment. If necessary, protective measures must be taken for the PPR tube, and a protective layer can be wrapped on the outside of the tube to protect it.
3. Because the PPR pipe will expand and contract in a specific environment, so in the construction, relevant technical methods must be used to prevent the deformation of the water pipe.
4. After the water pipe is installed, it must be tested for pressure. The pressure test pressure and pressure test time must be carried out according to the technical requirements, and the pressure and time values of different types of water pipes are different, and the pressure test must be carried out in strict accordance with the technical manual.
5. In the process of pipe laying, according to the safety distance and technical requirements, install the holding card to fix it to ensure the safety and stability of the PPR water pipe when it is over water.
