In the winter, in order to makepe pipeCan play a better role, but also in order to avoid being frozen, it is necessary to do a good job in the relevant insulation work, the specific should be how to do it?

For the insulation work of pe pipes, the insulation layer should be done after the anti-corrosion and hydraulic test are qualified, and then some positions should be set aside at the interface and weld of the pipeline, and the insulation work should be carried out at the interface after the hydraulic test is qualified. Before heat preservation, the debris in the trench pipe must be cleaned up, and the debris left in the construction should be cleaned at any time to ensure smooth flow. If it is used for pipes that need to be insulated in the well, the soil layer can be sealed during construction only after the anti-corrosion pressure test is qualified and the insulation inspection is completed. Note that it is strictly prohibited to reverse the process.

In addition, in the construction process of pe pipe, we should also pay attention to the cleaning of the pipeline, and the construction port should be blocked in time to avoid water and debris from entering the pipeline.
