Polyurethane insulated spiral steel pipe

The full name of polyurethane insulation pipe is high-density polyethylene plastic outer protective polyurethane foam prefabricated direct-buried insulation pipe. It is composed of a working steel pipe for transporting media, a polyurethane insulation layer, and a polyethylene plastic outer protective pipe, which are combined outwards in sequence through equipment.

Insulated pipe is the abbreviation of insulated pipe. Insulated pipe is used for the transportation of liquids, gases and other media. It is used in the insulation engineering of pipelines in petroleum, chemical industry, aerospace, hot springs, military, central heating, central air conditioning, municipal administration, etc.

High-density polyethylene plastic-exterior polyurethane foam prefabricated direct-buried insulation pipes are very popular for their excellent performance, convenient construction and long service life.

Its structure is composed of three parts: outer protective layer, thermal insulation layer and anti-leakage layer. The material of the outer protective layer is polyethylene jacket tube or fiberglass or other materials.

There are three laying methods: direct burial, overhead, and trench.

Thermal insulation pipe is suitable for transporting various media in the range of -50℃-150℃. It is widely used in central heating, cooling and hot oil transportation, as well as thermal insulation and cold insulation projects in greenhouses, cold storages, coal mines, petroleum, chemical and other industries.
