Nowadays, in our family decoration, most of the time can not be separated from the water pipe, PPR water pipe installation as an important part of the hidden project, in addition to the quality of the water pipe material, the correct construction steps are also very important. Generally in the kitchen, living room PPR water pipe best “go to the top, go to the wall, do not go to the ground”. Here we introduce the installation skills of PPR water pipe and the installation steps of PPR water pipe.

PPR water pipe installation Step 1 Check and accept materials

The quality of construction materials directly affects the construction quality and the hidden danger brought by the poor materials in the future. Before installation, the water pipe should be strictly checked. The inner and outer walls of the water pipe should be smooth and flat, without bubbles, cracks, cracks, dents, peeling, serious cold spots and obvious traces.

Installation of the PPR water pipe Step 2 Provide information on site

Installation personnel should carefully read the drawings, confirm the location of water heaters, sinks, basins, washing machines and other facilities and equipment, know whether there is any special requirements of the owner or designer, if there is any special requirements should be in accordance with the instructions of the owner or designer construction.

PPR pipe installation Step 3 Cut pipes

In order to avoid unnecessary waste in the installation process, the installation personnel should measure the length of the required pipe and cut it. The bayonet of the pipe scissors should be adjusted to match the diameter of the cut pipe. The force should be applied evenly when rotating cutting off. When the pipe is broken, the section should be perpendicular to the axis of the pipe.

Installing the PPR water pipe Step 4 Connect the pipes

PPR water pipe and pipe fittings are connected by hot melt, hot melt connection is the most reliable, easy to operate, good air tightness, high interface strength. Dust and foreign matter should be removed from pipes and accessories before connection. Welding machine shall be used to heat pipes and fittings for pipe connection. The depth and time of hot melting of pipes and fittings shall meet requirements. Do not rotate during hot melt welding. When connecting the pipe with silk, the raw material belt should be wrapped to ensure the sealing.

Installing the PPR pipe Step 5 Secure the pipe

In order to ensure that water pipes will not resonate due to water pressure in future use, all water pipes must be fixed by pipe clamp. The pipe clamp spacing is 400-500mm, the outside diameter of the pipe is less than 25mm, the corner and the water meter and pipe terminal 100mm set pipe clamp. In special cases, if the water pipe goes through the geosyncline, the thickness of the mortar buried should be greater than 100mm.

After the installation of the water pipe, the pressure test shall be carried out. After the installation of all the inner wire bends, the bulkhead or triangle valves shall be installed to ensure the sealing.

Water pipe pressure test is to ensure the quality of water pipe and installation quality test, water pipe pressure test using pressure pump into the pipe ≥0.6Mpa pressure (some manufacturers in order to reflect the quality of their own brands of pipes, recommended pipe pressure 0.8Mpa). The pressure measurement time is not less than 30 minutes, and the pressure drop is < 0.05Mpa.
