Direct Buried Pipe Insulation

Polyurethane direct buried insulation tube is made of high performance polyether polyol composition and multiple methyl polyphenyl polyisocyanate as raw materials and then chemically foamed.

Direct buried pipe insulation.

Fabricated shapes parts molded cast polymer chemical system. The prefabricated directly buried insulating pipe is suitable for conveying all kinds of media in the range of temperature from 50 c to 150 c. The foamglas insulation system consists of foamglas cellular glass insulation and flexible pittwrap jacketing. The pipes are widely used in urban central heating heating room cold storage coal mine oil port air conditioning chemical industry and so on.

The direct burial of insulated pipelines is often the most practical method of installing underground piping systems. This is exactly the heat supply project of polyurethane thermal insulation direct buried pipe in our country. This method elimi nates the need for costly tunnels and speeds the installation of the piping system. The high temperature prefabricated direct buried insulation pipe not only has the advanced technology and practical performance which is difficult to compare with the traditional.

Direct buried insulation pipe is a kind of direct buried prefabricated insulation pipe with good insulation performance safety and reliability and low project cost. The direct buried thermal insulation pipe is composed of a steel pipe for conveying the medium a high density polyethylene outer pipe and a rigid polyurethane foam insulation layer between the steel pipe and the outer pipe.
