Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of assembly type pipeline heat preservation structure, specifically to an assembly type pipeline heat preservation structure. BACKGROUND

[0002] In order to reduce the medium heat loss, meet the production needs of pressure and temperature, and improve the labor conditions and environmental health, when laying the pipeline, the heat preservation structure is generally added outside the pipeline. The previous pipeline heat preservation layer adopts wrapping a layer of rock wool on the outer wall of the pipeline, and then fixing the rock wool by using an aluminum sleeve. In order to ensure that the gap at each connection is small to ensure the heat preservation performance, this installation method is more difficult. The assembly type pipeline heat preservation structure appeared later, which mainly improves the direction of splitting the aluminum sleeve into two semicircular shells, preinstalling rock wool and other heat preservation corrosion-resistant materials in the shell, and then fastening and connecting the two shells to complete the installation after buckling on the pipeline.
