Many people are not very familiar with the structural mechanism of PU insulated pipelines. Today PU Insulated Steel Pipe Manufacturer Let us look at the structural mechanisms of PU insulated pipelines—how they are classified and what functions they serve.
The structural mechanism of PU insulated pipelines can be divided into the following points:
1. Anti-corrosion coating: protects the outer steel pipe from corrosive substances, extending the service life of the steel pipe.
2. Outer protective steel pipe: protects the insulation from groundwater erosion, supports the carrier pipe, and can bear certain external loads to ensure normal operation of the carrier pipe.
3. PU foam layer: maintains the medium temperature and keeps the outer jacket surface at ambient temperature.
4. Barrier/reflective layer: prevents organic foam from entering the inorganic rigid high-temperature layer; reflects part of the heat from the high-temperature layer.
5. Inorganic rigid insulation layer: withstands high temperature, ensures the interface temperature with the organic insulation layer, and prevents the foam from being carbonized.
6. Friction-reducing layer: ensures free thermal expansion and contraction of the carrier pipe.
7. Carrier pipe: ensures normal flow of the conveyed medium.
Urban and rural construction is advancing rapidly. With growing national strength, heating-pipe insulation continues to improve. Advocating energy conservation, reducing heat loss, and lowering project cost have become major development trends in the heating-pipe insulation industry.
