Disassembered insulation tube shell

Abstract

The invention provides a detachable thermal insulation casing and an assembling and installation method thereof and belongs to the technical field of thermal insulation casing. According to the detachable thermal insulation casing, a first layer of thermal insulation cotton, a second layer of thermal insulation cotton and a third layer of thermal insulation cotton are arranged in a staggered mode in the annular and longitudinal directions; the exterior of the third layer of thermal insulation layer cotton is provided with a pipe casing fixing frame; the first layer of thermal insulation cotton, the second layer of thermal insulation cotton, the third layer of thermal insulation cotton and the pipe casing fixing frame are fixedly connected through high temperature resistant low heat conducting connecting parts; an extensible pipe casing is arranged inside the thermal insulation casing according to the extension capacity of a pipeline; an extension portion is formed by materials with super low thermal conductivity coefficient; the extensible pipe casing is formed by an inner portion and an outer portion which are overlapped; the two portions are in normal thermal insulation thickness and accordingly when the extensible pipe casing is stretched out or draws back, the thermal insulation effect at the extensible pipe casing position is not influenced. The detachable thermal insulation casing has the advantages of being convenient and rapid to install, not easy to fall off when being installed, good in insulation effect, allowing detachment for a plurality of times and allowing integral detachment due to the fact that the pipe casing is connected by the high temperature resistant low heat conducting connecting parts.

Description

technical field [0001] The invention relates to a detachable heat-preservation pipe shell and its assembly and installation method, belonging to the technical field of heat-preservation pipe shells. Background technique [0002] The insulation construction of the pipeline is very important. The traditional insulation structure has complicated construction, poor operability, and relatively large heat loss. [0003] Traditional thermal insulation structure construction usually adopts two methods: [0004] 1. Use soft thermal insulation cotton, wrap it layer by layer on the outside of the pipe according to the thickness of the insulation and tie it layer by layer with iron wire. This construction method is random, non-standard, low in efficiency, and poor in insulation effect. If it is damaged, it will be troublesome to disassemble. It is not easy to maintain, and only new insulation cotton can be replaced, which wastes labor and resources; [0005] 2. Use two halves of the p...

AI Technical Summary

Problems solved by technology

Since the expansion coefficient of the pipe is larger than that of the insulation tile, if it is installed in a cold state, after the pipe is heated up, a large axial gap will be formed between adjacent insulation tiles, thereby forming convection and radiation heat transfer, increasing the temperature. heat loss
