Abstract

The invention relates to the technical field of pipeline heat preservation, in particular to a pipeline heat preservation structure. The pipeline heat preservation structure is characterized in that aheat insulation layer 2, a fixing layer 3 and a protective layer 4 are sequentially arranged outwards from an outer wall 1 of a pipeline. According to the pipeline heat preservation structure, the heat insulation layer is formed by splicing heat insulation plates which are prepared from nano powder, and the thickness of the heat insulation layer is 5-50 mm; the fixing layer 3 is composed of glassfiber strips and plays a role in fixing the heat insulation plates; a reflecting layer 5 is aluminum foil, the mirror surface of the reflecting layer 5 can reflect infrared rays to further improve the heat insulation effect; and the protective layer 4 is metal or metal alloy, two metal skins matched with the model of the pipeline are buckled up and down on the steam pipeline, the steam pipeline is just matched and connected with the metal skins, and the rivet fixing is reduced. The pipeline heat preservation structure has the advantages of being thin in thickness, easy to construct, environment-friendly in construction, long in service life, strong in stability, free of recovery cost and the like.

Description

technical field [0001] The invention relates to the technical field of pipeline insulation, in particular to a pipeline insulation structure. Background technique [0002] Most of the existing thermal insulation systems for pipelines use an insulation layer made of aluminum silicate insulation materials such as mineral wool or rock wool, which is directly integrally formed outside the pipeline. In order to achieve a better thermal insulation effect, the thickness of the insulation layer arranged outside the pipeline is relatively large, which brings difficulties to the transportation and installation of the pipeline. Moreover, when the insulation layer of the pipeline has problems such as damage that affects the insulation effect, it is often necessary to replace the entire insulation pipe, which not only increases the manpower and material costs for maintenance, but also causes a lot of waste. [0003] Moreover, aluminum silicate insulation materials such as mineral wool o...
