Docking method of 1.PPR water pipe
1. Turn on the power of the fuser, and wait until the temperature reaches the predetermined temperature before starting the subsequent operation.
2. Before hot-melt connection, cut the pipe to make the end face perpendicular to the pipe axis; In the choice of cutting tools, special pipe shears are generally selected; If it is that kind of large diameter, it should be cut with a saw blade. After cutting, it is necessary to remove burrs and burrs to keep the edge smooth.
3. The end face of pipe grid connection between pipes must be kept clean, dry and oil-free.
4. Mark before hot melting, and mark the specific depth of hot melting on the pipe with calipers and pencils to avoid excessive hot melting.
5, hot melt elbow, must according to the design drawings or construction scheme, and pay attention to its specific direction, in this piece can be marked with auxiliary signs.
6. When connecting, do not rotate the guide pipe end into the hot sleeve until it reaches the marked depth. This process can't rotate, and then push the pipe onto the heating pipe until the position reaches the specified mark. The heating time depends on the specific heating progress, and the whole heating process should be paid attention to; When the hot-melt flange body appears above the die head, the die head on the pipeline can be removed and the subsequent operation can be continued.
7. After heating for a predetermined time, the heating jacket of the pipe can be completely removed, and the horizontal direction can be inserted to the pre-marked depth very quickly to form a uniform flange body with the joint.
8, in the whole insertion process, don't rotate the insertion, it is easy to make the tube can't keep level and smooth.
9. Installation of supports and hangers
(1) When installing the pipeline, the pipe clamp and the fixed hanger must be set according to the size of the pipe diameter, and the position and interval should be consistent. The pipe clamp is in close contact with the pipeline, and the surface is free from damage.
(2) If a metal hanger is used, it is best to take protective measures between the metal card and the pipeline. Plastic bags or rubber can be used as gaskets to prevent the surface from being cut.
Summary: The above is about the docking method of water pipes and the hot melt connection steps of PPR pipes. In fact, I really didn't expect that there are so many details to be paid attention to in a water pipe docking, so when you are looking for a hydropower master to decorate, you should choose those experienced masters whose technology and experience are more reliable.
