PPR pipe fittings why will occur at the connection burst
PPR pipe fittings why will occur at the connection burst
Hot melt method can be used to connect the PPR pipe fittings, but sometimes in the connection will happen burst because of what? Below small make up for everybody to introduce:
First, it may be the temperature of the hot melt welding machine is not correct, too high or too low, so that changes in the performance of polypropylene. Second, the size of the welded sleeve is incorrect, so that the melting depth and the welding structure of the pipe are not appropriate. Third, the surface of welding set has not dealt with, or surface coating, the contact part of the pipe with hole. Fourth, welded pipes and tubes do not maintain concentric or straight line.
Above is for the PPR pipe connection of the cause of the explosion, I hope you can understand these knowledge.

Knowledge analysis on impact toughness of PPR pipe fittings
Knowledge analysis on impact toughness of PPR pipe fittings
PPR pipe impact toughness is refers to the pipe fittings to resist impact load without damaging the ability, the following small series will be introduced to you about the impact toughness of PPR pipe:
First of all, the pendulum impact test, after the destruction of the gap in the unit area of the power consumption to say more, the more energy absorption pipe before fracture, the toughness of PPR pipe. Then, the impact toughness of PPR pipe fittings will be affected by the temperature and time, when the temperature dropped to a certain temperature range, the sudden drop significantly, the pipe will begin to show brittle fracture.

Introduction to the related knowledge of PPR pipe fittings
Introduction to the related knowledge of PPR pipe fittings
PPR pipe fittings in the cold water piping system should not be greater than 40 degrees Celsius, the water temperature in the hot water piping system should not be greater than 90.
PPR supply pipe should be set in the dark tube or pipe hole, water surface of the riser should be arranged in the sanitary ware and more concentrated with local water consumption, and should be arranged in the corner is not vulnerable to external impact. Water can cross pipe laying in the ceiling or trench, can also be laid on the floor in the leveling layer. PPR pipe should not pass through the expansion joints, settlement joints, such as must pass through, should take the necessary technical measures. If the pipe should be placed outside the open and bright, the pipe should be placed in the light of the direct exposure to the sun. In areas where there is a potential for freezing, there should be anti freezing measures for outdoor and outdoor piping.
Note that the pipeline shall be laid in the flue duct, and drainage; not through the stool trough, trough urinal; not through distribution room, warehouse, storage room and other rooms.
