What should be paid attention to when using pp pipe construction? As a kind of special plastic pipe, because of its perfect performance, it is mostly used in building cold and hot water discharge and switching system in life. So what should we pay attention to in the process of using pp pipe?

1, first of all, if the pipe is the device in the outdoor, because if a long time by direct sunlight, it will easily lead to material aging degradation, thus affecting the quality of use, so remind the construction personnel to bandage dark protective layer, in order to play a protective role. In addition, during transportation, in order to avoid product damage caused by external forces, it is necessary to do a good job of protection.
2. The linear expansion coefficient of pp pipe is relatively large. When the pipe is installed or not directly buried, appropriate measures must be taken to prevent it, and supports and hangers must be installed. And the installed pipeline can not be heavy pressure, knock, if necessary, the parts vulnerable to external force cover protection. If it is dark, pay attention to mark the specific location of the pipeline, so as not to damage the pipeline in the later secondary construction.
3. After the construction is completed, the pressure test shall be carried out before sealing the pipe and covering the decorative layer. The pressure test of cold water pipe shall be 1.5 times of the working pressure of the switcher, but shall not be less than 10MPa. Hot water pipe test pressure is 2 times the working pressure, but not less than 1.5MPa. Pressure test time and method technical regulations.
