polyurethane Recent price of thermal insulation materials
Thermal insulation materials are used for all kinds of cold water, cold air, cold oil pipelines, round, shaped and any shape The Conduit Insulation. Prevent condensation: ethylene foaming Pipe The material is a closed cell structure, which is insulated by the gas in the closed cell rather than polyethylene material. It has good resistance to water vapor penetration. The built-in vapor barrier formed is both a thermal insulation layer and a vapor barrier, and no additional vapor barrier is required. The moisture resistance factor is much larger than other insulation materials. It can effectively avoid condensation.
Thermal insulation pipe form:
(1) Working steel pipes: according to the technical requirements of the transmission medium, seamed steel pipes, seamless steel pipes and double-sided submerged arc spiral welded steel pipes are used respectively. (2) Thermal insulation layer: rigid polyurethane foam. (3) Protective shell: high-density polyethylene or glass fiber reinforced plastic. (4) Leakage * * * line: When fabricating high-temperature prefabricated directly buried insulation pipes, * * * line is embedded in the insulation layer near the steel pipe. Once leakage occurs somewhere in the pipe, through the conduction of the alarm line, * * * on the * * * detection instrument can * * * show the exact location of the leakage and the size of the leakage degree, so as to notify the maintenance personnel to quickly deal with the leaking pipe section and ensure the safe operation of the heating network.
More recently, the relevant * * * has redefined green materials - materials that have less impact on the earth's environment and are conducive to human health in the processes of raw material adoption, product manufacturing, use or recycling and waste disposal, also known as "environmental coordination materials".
Thermal insulation pipe has become a relatively mature advanced energy-saving technology in some developed countries abroad. With its excellent performance, convenient construction and long service life, it has brought huge economic and social benefits to users. This energy-saving technology is being used more and more widely in China
Product description
The high-temperature prefabricated directly buried insulation pipe mainly consists of four parts.
(1) Working steel pipes: according to the technical requirements of the transmission medium, seamed steel pipes, seamless steel pipes and double-sided submerged arc spiral welded steel pipes are used respectively.
(2) Thermal insulation layer: rigid polyurethane foam.
(3) Protective shell: high-density polyethylene or glass fiber reinforced plastic.
(4) Leakage * * * line: When fabricating high-temperature prefabricated directly buried insulation pipes, * * * line is embedded in the insulation layer near the steel pipe. Once leakage occurs somewhere in the pipe, through the conduction of the alarm line, * * * on the * * * detection instrument can * * * show the exact location of the leakage and the size of the leakage degree, so as to notify the maintenance personnel to quickly deal with the leaking pipe section and ensure the safe operation of the heating network.
