Insulation Pipe

Apr 25, 2024
Thermal insulation pipe is the abbreviation of insulated pipe. It 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 in greenhouses, cold storages, coal mines, petroleum, and chemical industries. Thermal and cold insulation projects in other industries.
Insulated pipe structure
High-temperature prefabricated direct-buried insulation pipes mainly consist of four parts.
(1) Working steel pipe: 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.
(2) Insulation layer: made of rigid polyurethane foam.
(3) Protective shell: made of high-density polyethylene or fiberglass.
(4) Leakage alarm line: When manufacturing high-temperature prefabricated direct-buried insulation pipes, an alarm line is buried in the insulation layer close to the steel pipe. Once leakage occurs somewhere in the pipeline, special detection instruments can be detected through the conduction of the alarm line. It will alarm and display the exact location of the leak and the extent of the leak, so that maintenance personnel can be notified to deal with the leaking pipe section quickly to ensure the safe operation of the heating network.
 
Characteristics of thermal insulation pipe
High-temperature prefabricated direct-buried thermal insulation pipe-advantages and features
1. It has strong corrosion resistance and waterproof ability and low overall cost.
According to calculations by relevant departments, double-pipe heating pipes can generally reduce the project cost by about 25% (using fiberglass as the protective layer) and 10% (using high-density polyethylene as the protective layer).
2. Low heat loss, saving energy. Heat loss is only 25% of traditional pipes
Directly buried thermal insulation pipe Thermal conductivity 0.022kcal/m.h.℃ Water repellency 0.03kg/cm³
3 Long service life
Proper installation and use can extend the life of the pipe network to 30-50 years with extremely low maintenance costs.
4. Small footprint, fast construction, and conducive to environmental protection.
It can reduce the amount of earth excavation by more than 50% and the amount of earthwork masonry and concrete by 90%.
