Steel sleeve steel prefabricated buried steam insulation pipeline is an efficient insulation, anti-corrosion, and corrosion-resistant pipeline composed of inner working steel pipe, outer protective steel pipe, and intermediate insulation layer. The inner steel pipe adopts an organic silicon high-temperature resistant paint anti-corrosion coating, and the pipe mouth is sealed with a polyene film or three-layer PE cold winding tape, which can effectively prevent corrosion and extend the service life. The insulation layer is made of centrifugal glass wool and wrapped in multiple layers of stagger
