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 or FRP.(4) leakage alarm line: manufacturing high temperature prefabricated straight buried insulation pipe, near the steel pipe insulation layer, buried alarm line, once pipe somewhere leakage, through the alarm line conduction, can alarm on the special detection instrument and shows say eksakton pasen tan say grado na panag-awit, ta pian makapangipaamta na saray totoon maples ya mangasikaso ed panagmintina a maples, seguroen ya say maligen ya operasyon na saray heath ner dia et 15} . {17}.
