1. After the measurement length of PPR pipe fittings is determined, the hacksaw can be used for manual cutting or circular saw blade and sawing machine can be used for cutting.
2. One expansion joint is installed on each layer of the riser to compensate for the thermal expansion and cold contraction of the countercurrent pipe. Thirdly, pay attention to the direction along the water when installing the tee to facilitate the natural formation of slope when installing the horizontal pipe. If the height of each floor of the riser is less than 3m, consider setting a pipe hoop.
3. For PPR pipe fitting adhesion test, the outer pipe end with a length of about 50mm of the inserted pipe and the pipe fitting bearing interface wall must be cleaned before assembly, and then coated with acetone cotton, brushed and scrubbed evenly once, and then coated with adhesive evenly without omission Then rotate to the ideal combination angle, insert the pipe into the socket of the pipe fitting, knock with a wooden mallet to make the pipe completely inserted into the socket, do not disassemble or change the direction within two minutes, and wipe off the adhesive in time to keep the pipe clean. The straight-line distance of horizontal pipe and drainage pipe shall meet the requirements, and inspection port or cleaning port shall also be set.
