Polyurethane phaephe bakeng sa patoa go tuka ga molelo .
High temperature prefabricated directly buried insulation pipe is composed of steel pipe, FRP inner sheath, FRP shell, which is characterized by: also includes high temperature insulation layer, lubrication layer, elastic seal. The utility model effectively solves the problems of insulation, sliding lubrication and waterproof of prefabricated direct buried insulation pipe for 130℃-600℃high temperature heat transfer in central towns. High temperature prefabricated directly buried insulation pipe is mainly composed of four parts.(1) Working steel pipe: according to the technical requirements of conveying medium, use seamless steel pipe, seamless steel pipe, double-sided buried arc spiral welded steel pipe.(2) Insulation layer: using rigid polyurethane foam plastic.(3) protective shell: using high-density Polyethylene kapa FRP.(4) Leakage mola alamo: tlhahiso phahameng thempereichara prefabricated otlolohile epetsoeng kwahelang phaephe, haufi le tšepe pipe kwahelang lera, buried alamo mola, hang phaephe kae kae lekatsa, ka mola alamo conduction, ka alama ka khethehileng phumano seletsa le bontša sebaka se nepahetseng le lekhali le tekanyo ea ho dutla e qetellang ea ka potlako a tshebetso ya ka potlako a, ka order e le e inehetseng ( Kaofela har'a dikarolo tse tharo. polyurethane ka ho toba e bolokilweng kwahelang pipe mafome e na le thepa e ntle mochine le thepa mogote, hangata ho hanyetsa mocheso 120 ka phetolo kapa motsoako o mong le mocheso insulation thepa 180.
