Matters needing attention：

1, PPR pipe and pipe fittings are connected by hot melt, but can not be directly in the pipe and pipe fittings sleeve wire, and metal pipe connection can be used flange connection, and water heater connection must be used with metal insert fittings;
2, in the process of hot melt connection must use reliable hot melt equipment, it can ensure the quality of welding;
3. When using special scissors to cut PPR pipe vertically, the incision should be kept smooth and burr free;
4, PPR pipe and pipe fittings welding parts must be clean, to prevent sand damage to the quality of the joint;
5. When inserted into the welding, the equipment must be heated in accordance with the specified time of the pipe and fittings;
6. Take out the pipe and fittings immediately after the heating is completed, and connect them. If the two positions are found to be wrong, you can adjust them in a certain time;
7. After the agent PPR pipe connection, both hands must grip the pipe and fittings to maintain sufficient cooling time, and you can let go to continue to install the pipe when the cooling reaches a certain degree. After connecting the white PPR pipe, the specific position of the pipeline should be marked on the wall or ground with colored paint to avoid damaging the pipe fittings again.

Installation attention：

1. PP-R pipe has low hardness and poor rigidity compared with metal pipe. It should be protected during handling and construction to avoid mechanical damage caused by inappropriate external force. In the dark compress to mark the location of the pipeline, so as not to damage the pipeline second decoration.
2, PP-R pipe below 5℃ there is a certain low temperature brittleness, winter construction should be careful, the pipe should be cut slowly with a sharp tool. The installed pipes should not be pressed or knocked, and the parts vulnerable to external forces should be covered with protective materials if necessary.
3. PP-R tube is easily aged and degraded by ultraviolet radiation for a long time. Dark protective layer must be wrapped when installed outdoors or in direct sunlight.
4. In addition to the mechanical connection with threaded inserts or flanges for connecting the PP-R pipe with the metal pipe or water applicator, the rest should be connected by hot melt, so that the pipe is integrated and there is no leakage point.
5. The linear expansion coefficient of PP-R tube is large (0.15mm/m℃), so technical measures must be taken to prevent the expansion and deformation of the pipe when it is openly installed or not directly buried.
6. Pressure test must be conducted before sealing pipe (directly buried) and covering decorative layer (not directly buried and dark) after pipe installation. The test pressure of cold water pipe shall be 1.5 times of the working pressure of the system, but shall not be less than 1MPa; The test pressure of the hot water pipe shall be 2 times of the working pressure, but not less than 1.5MPa. Pressure test time and method of technical regulations.
7. When the PP-R pipe is applied openly or not directly buried, the support and hanger must be installed according to the regulations.
8, cool to the specified time, complete the connection.
