Description of Polyurethane Prefabricated Insulation Pipe

The full name of polyurethane prefabricated insulation pipe is high-density polyethylene outer protective pipe rigid polyurethane foam plastic prefabricated direct buried insulation pipe. It consists of a working steel pipe for conveying medium, a polyurethane rigid foam plastic insulation layer, and a polyethylene plastic outer protective pipe from the inside to the outside. It has many advantages such as low project cost, low heat loss, energy saving, corrosion resistance, good insulation performance, long service life, small footprint, fast construction, and environmental protection. It is used for liquid gas transmission pipelines, chemical pipeline insulation projects, petrochemical centralized heating pipelines, etc.
