Abstract

The invention belongs to the technical field of pipeline heat preservation, and particularly discloses a pipeline heat preservation layer structure capable of being locally disassembled and assembled and a design and installation method.The heat preservation layer structure comprises a groove section heat preservation layer, a boss section heat preservation layer and a bent pipe section heat preservation layer, and the groove section heat preservation layer comprises a groove section heat preservation layer A and a groove section heat preservation layer B; the boss section heat preservation layer comprises a boss section heat preservation layer A and a boss section heat preservation layer B. The bent pipe section heat preservation layer comprises a bent pipe section heat preservation layer A and a bent pipe section heat preservation layer B. The heat preservation layer is simple in structure, can be disassembled and assembled in a segmented mode and can be automatically fixed, the design method is simple, the installation method is flexible and convenient, and the heat preservation layer can be fixed without other fixing bandages.

Description

technical field [0001] The invention belongs to the technical field of pipeline insulation, and in particular relates to a partially detachable pipeline insulation layer structure and a design and installation method thereof. Background technique [0002] In nuclear fusion reactors in which helium is used as a coolant, some pipeline gases contain tritium. Many of these pipelines are still high-temperature pipelines, and the temperature in some working conditions is as high as 500°C. It is necessary to insulate these pipelines and set up an insulation layer to prevent Personnel burns. At the same time, due to the effect of tritium, traditional rubber bands cannot be used when the insulation layer is fixed. Moreover, the welds and other parts of these pipelines need to be inspected from time to time. Some pipelines in the experimental section need to change the position of the strain gauge or thermocouple several times according to the purpose of the experiment. If the tradit...

At the same time, due to the effect of tritium, traditional rubber bands cannot be used when the insulation layer is fixed

Moreover, the welds and other parts of these pipelines need to be inspected from time to time. Some pipelines in the experimental section need to change the position of the strain gauge or thermocouple several times according to the purpose of the experiment. If the traditional iron wire or iron hoop is used to fix the insulation layer, it is inconvenient to disassemble and It cannot be disassembled in sections, and the fixing method of the insulation layer becomes a difficult problem
