PPR water pipes have good toughness, high strength, easy maintenance and long service life. When using PPR water pipes, pay attention to heat preservation measures during low temperature. The following is the maintenance method of PPR water pipes.
1. PPR water pipes should be concealed under pressure. Generally, the working pressure should be used as the holding pressure, and the pressure can be removed after the concealed layer reaches the permitted strength.
2. Because the road texture is soft and its own mechanical strength is not as high as that of steel pipes, physical damage must be strictly prevented. After installation, the pipeline is strictly prohibited from knocking, bumping, smashing, or pressing. Cover protection measures should be taken before concealment. The pipeline located in the pipeline well Before sealing, take certain measures to prevent bricks, debris, etc. from falling down and breaking the pipe; due to the constituent elements of the ppr pipe, it is necessary to prevent chemical damage, which is easily overlooked during construction, and it is installed outdoors or in sunlight. Directly exposed pipelines should be covered with a dark protective layer to prevent chemical damage to the pipeline caused by sunlight.
3. During the low temperature period in winter, if there is no good insulation measures, the water in the PPR pipe should be blown out in time to prevent the pipe from freezing.
4. After the concealment is completed, a mark must be made to prevent other construction from damaging the pipeline.
