How to prevent some problems when using aluminum alloy lined PERT pipe?

The aluminum alloy lined PERT pipe has a certain pressure resistance, and has a certain thermal insulation effect when it is selected to be used. Can guarantee good use effect, so how to prevent some problems when using it?

1 . The installed floor heating pipes are connected by pipes and there is a danger of water leakage.
Precautions: Heating pipes buried in the fill layer need to have no joints. During the inspection, it is found that the piping is damaged, and if it is necessary to add joints for repair, it is necessary to prepare the construction department and the supervision engineer, and implement it after approval.

2 . Pipe breaks during cold bending
Reason analysis: The bending radius of the aluminum alloy lined PERT pipe is too small, which will break the pipe.
Preventive measures: Regulations "Installation of heating pipes for low temperature hot water systems" 5.3.3 The bending radius of plastic pipes shall not be less than 8 times the outer diameter of the pipes.
The right way to bend: The bend radius will not break the pipe. The degree of bending should also be reduced accordingly, so as to facilitate the use of pipes.

3. If the correct water pressure test and adjustment of the water-passing method are not correct, the pipes will leak water in the subsequent use.
Precaution:
The test pressure test of the aluminum alloy lined PERT pipe in use is carried out twice before the concrete filling layer is poured and after the curing period of the filling layer expires. The hydraulic test is based on each group of water separator and water collector. Please set it as 1.5 times the working pressure, 0.6MPa or more.

During the initial heating of the production line adjustment, the hot water temperature rises slowly, and the temperature needs to be about 10 degrees higher than the ambient temperature at that time and below 32 degrees. After 48 hours of continuous operation, the water temperature will rise by 3 degrees every 24 hours.

The above is the specific introduction of how to prevent some problems in the use of aluminum alloy lined PERT pipes. If there are some common problems, it is necessary to take measures to deal with them in time, so as to ensure a good effect of later use, water pressure problems or water The temperature problem will affect the overall effect. If there is a problem caused by improper operation, it needs to be solved in time.
