PPR water pipe installation is an important part of concealed works. In addition to the quality of water pipe materials, the correct construction steps are also very important. Generally, PPR water pipes in kitchen and living room are best to "walk on the top, wall and not on the ground". Next, Xiaobian will explain the PPR water pipe installation in detail.

ppr water pipe installation is an important part of concealed works. In addition to the quality of water pipe materials, the correct construction steps are also very important. Generally, PPR pipes in kitchen and living room are the best “ Walk on the top, walk on the wall, and don't walk on the ground ”. Next, Xiaobian will explain the PPR water pipe installation in detail. Let's have a look

PPR water pipe installation strategy

PPR water pipe installation steps 1. Material acceptance

the quality of construction materials directly affects the construction quality and the hidden dangers caused by poor materials in future use. 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, depressions, peeling, serious cold spots and obvious traces

ppr water pipe installation steps 2. Site disclosure

the installer should carefully read the drawings to confirm the location of water heaters, sinks, basins, washing machines and other facilities and equipment, and understand whether the owner or designer has special requirements. If there are special requirements, the construction should be carried out in accordance with the owner or designer's instructions

PPR water pipe installation step 3. Pipe cutting

in order to avoid unnecessary waste during installation, the installer should measure the length of the required pipe and cut it. The pipe cutting adopts special pipe scissors. The bayonet of the pipe scissors should be adjusted to match the diameter of the pipe being cut. The force should be applied evenly during the rotary cutting. When the pipe is broken, the section should be perpendicular to the pipe axis. After the cutting, the fracture is round and the section is free of burrs

ppr water pipe installation step 4. Pipe connection

ppr water pipe is connected with pipe fittings by hot melting, which is the most reliable, easy to operate, good air tightness and high interface strength. Before connecting, remove the dust and foreign matters on the pipes and accessories. The pipes and fittings shall be heated by welding machine, and the hot melting depth and time of pipes and fittings shall meet the requirements. Do not rotate during hot melt welding. When connecting the threaded pipe fittings, wrap the raw material tape to ensure sealing

ppr water pipe installation step 5. Pipe fixation

in order to ensure that the water pipe will not resonate due to water pressure in future use, all water pipes must be fixed with pipe clamps. Pipe clamps with a spacing of 400-500mm and an outer diameter of less than 25mm shall be set at the corners, water meters and 100mm at the pipe terminals. In case of special circumstances, the thickness of mortar landfill for water pipes that go through the trench should be > 100mm。

after the installation of the water pipe, the pressure test should be carried out. All installed inner wire bends need to be installed with bulkhead or triangle valve to ensure sealing

water pipe pressure test is to ensure the test of water pipe quality and installation quality. Water pipe pressure measurement uses a pressure pump to inject &ge into the pipe; 0.6MPa pressure (some manufacturers recommend 0.8MPa pressure in the pipe in order to reflect the quality of their own brand pipes.), The pressure measurement time is not less than 30 minutes, and the pressure drops < 0.05Mpa。

when installing water pipes, they should be horizontal and vertical, hot on the left and cold on the right, with a spacing of ≥ 30mm。 The distance between cold and hot water outlet pipes shall not be less than 150mm. The cold and hot water pipes cannot be perforated at the same time, and they should be perforated separately. When the water supply pipe is laid in parallel with the gas pipe, the distance is ≥ 50mm, cross laying distance ≥ 10mm。 When water pipes need to be installed on the balcony, water valves should be installed

this is a brief introduction to the above PPR water pipe installation strategy. I hope it will be helpful to you. Please look forward to more information
