Precautions for the construction of polyurethane insulation pipe

With the development of the pipeline industry, new materials are gradually appearing on the market. As an efficient product in the insulation industry, polyurethane insulation pipes have excellent insulation properties and efficient work efficiency. It has been widely used by people and has also been recognized by users. Polyurethane insulation pipe is a kind of direct buried pipe. It is necessary to take safety measures during construction, and the precautions during construction are also very important. Let us understand the precautions of polyurethane insulation pipe during construction.

First of all, when the polyurethane insulation pipe is constructed, it is necessary to check the flatness of the groove and the dryness of the bottom of the groove. At the same time, it is necessary to provide 200mm thick fine sand as the cushion layer, and also cover the fine sides of the polyurethane direct buried insulation pipe. sand. This is for the convenience of construction and the safety of the polyurethane insulation pipe.

Secondly, after the polyurethane insulation pipe is installed, the water pressure test is carried out. After the water pressure test is passed, the interface foaming treatment can be carried out. When the interface foaming treatment, the surface of the interface steel pipe is also cleaned, so as to improve the polyurethane insulation. The safety of the tube.

After the zui, when the polyurethane insulation pipe enters the building or the trench, it should be added through the wall casing to ensure the safety of the pipeline.

Although the polyurethane insulation pipe installation is convenient, some precautions are the key to improving the safety of the pipeline, so you must pay attention to these details when installing the polyurethane insulation pipe.
