How To Repair Poly PEX Fittings Failure

　　With the acceleration of our many urban planning and construction today, the demand for Poly PEX fittings is also very large, but in some cases, we cannot guarantee that the quality is all good, and the raw materials of the pipe fittings used in conjunction with each other They are all different, so the more serious level of damage to the pipes is also different. Today we will discuss the maintenance methods of common failures of the pipes.

　　1. For example, some of the more common faults of this stage are cracks in the connecting parts. This is because the time of heat fusion is also stressful in the case of construction. The operation is not good. It is also possible that some relatively sharp gravel was buried in the filling situation so that when the stones and pipes are squeezed, the Poly PEX fittings will be broken and water seepage.

　　2. In the case of maintenance, if only some sand holes or holes are directly used for maintenance of flange gate valves.

　　3. However, when the cracked part is larger, the following methods can be used to solve the problem.

　　(1) One of the methods is to use two gate valves and water pipes that need to be removed and replaced. This method has the advantage of being solved quickly when repairing is carried out, but the defect is that the bolts of the flange foundation are in the soil Yes, the plastic in the pipe clamp is very easy to be brittle, so it takes about 2 to 3 time. (2) There is also a way that the foundation pit does not need to be excavated independently of the Poly PEX fittings water pipe, and the docking machine is directly used to connect the two flange heads, and then the plastic expansion device is applied in the middle. The damage caused by the expansion and contraction of Poly PEX fittings is relatively small. However, in actual operation, it is necessary to dig a large working surface from the middle of the foundation pit, and then put it into the docking machine for connection.
