Description :
Application principle of prefabricated heat preservation pipe with steel sleeve The heat preservation pipe can play a good anti-corrosion role because the polyurethane rigid foam heat preservation layer is tightly bonded to the steel pipe skin, which can isolate the infiltration of air and water. At the same time, its foam pores are all closed, and its water absorption is very low. The high-density polyethylene shell and fiberglass shell both have good anti-corrosion, insulation, and mechanical properties. The application principle of steel sleeve prefabricated insulation pipe is that the material is a closed cell structure, which relies on gas insulation inside the closed cell instead of polyethylene material to achieve insulation. It has the ability to resist water vapor penetration and forms an internal vapor barrier, which is both an insulation layer and a vapor barrier, without the need for a separate vapor barrier. Moisture resistance factor μ; the value is much higher than other insulation materials. It can effectively prevent condensation from occurring. Performance and related indicators of insulation pipe: 1. Structure of insulation pipe. High temperature prefabricated buried insulation pipe mainly consists of four parts. (1) Working steel pipes: According to the technical requirements of the conveying medium, seamless steel pipes, double-sided submerged arc spiral welded steel pipes are used. The comprehensive thermal conductivity at the temperature is ≤ 0.06W/M.k, and the large heat loss is ≤ 120W/m2; The pipeline operates normally and has a service life of no less than 30 years. The steam composite insulation pipe consists of a working steel pipe, insulation layer, rolling guide pipe bracket, outer sleeve (steel pipe), and anti-corrosion layer. The insulation material is tied to the working steel pipe and moves as a whole through thermal expansion inside the outer sleeve by relying on the rolling guide pipe bracket, so it does not damage the insulation layer. The fixed bracket is an internal fixed bracket, which does not require the large reinforced concrete support pier of the original "three-way fixed bracket", making it an ideal way to lay steam pipes.
