as everyone knows, PPR water pipe yes Home piping A kind of water pipe material commonly used in Pipe installation The following PPR pipes are commonly used for home decoration. What aspects should be paid attention to in the installation process?

1. PPR pipe has lower hardness and poor rigidity than metal pipe, so it shall be protected during handling and construction to avoid mechanical damage caused by improper external force. After concealed laying, the pipe position shall be marked to avoid damage to the pipe due to secondary decoration.

2. PPR pipe has low temperature brittleness below 5 ℃. Be careful during winter construction. Use a sharp knife to cut the pipe slowly. Do not press or knock the installed pipe heavily.

3. PPR pipes are prone to aging and degradation due to long-term exposure to ultraviolet radiation. When installed outdoors or in direct sunlight, dark protective layers need to be wrapped.

4. PPR pipes shall be connected with metal pipes or water dispensers by means of mechanical connection such as threaded inserts or flanges, and the rest shall be connected by hot-melt to integrate the pipes without leakage points.

5. The linear expansion coefficient of PPR pipe is relatively large, so technical measures to prevent pipe expansion and deformation shall be taken when laying pipes in open installation or non direct buried concealed laying.

6. After the installation of pipes, pressure test is required before sealing and covering the decorative layer. The pressure test pressure of cold water pipe is 1.5 times of the working pressure of the system, but not less than 1MPa. The pressure test pressure of hot water pipe is 2 times of the working pressure, but not less than 1.5MPa. The pressure test time and method are specified in the technical regulations.

7. When PPR pipes are laid in the open or not directly buried, supports and hangers shall be installed as required.
