Buried prefabricated anti-corrosion seamless thermal insulation pipes and polyurethane directly buried thermal insulation pipes in Lijin County are developed in the developed world. This technology is relatively comparative. In recent years, the technology developed by the developed institute has also been introduced, and the whole staff has been trained through various technologies through continuous learning. The adaptability of this material is relatively stronger. It can be effectively bonded with the material. In addition, as only the pipe insulation layer is purchased, it is basically unnecessary to consider the bonding between some anti-corrosion layers and other layers. The adaptability of polyurethane insulation layer is relatively strong.

Buried prefabricated polyurethane heating insulation pipe In the process of selecting polyurethane hot water insulation pipe, everyone should effectively understand all devices, including these different lengths, their design range, all within the allowable range, and in the process of setting, the cable should be flat, It should be tightly attached to the surface of some containers, so that they can be fixed with adhesive tape. Do not bind them with other filaments, and pay attention to protecting them while using them.
