Abstract

The invention provides a heat insulating structure of a pipeline in order to solve the problems that an existing heat insulating structure of the pipeline is complicated in procedure and high in assembly cost. The heat insulating structure of the pipeline comprises a foundation pipe, and an inner protection layer, a connection layer and an outer protection layer are sequentially arranged along thewall of the foundation pipe from inside to outside. The connection layer is two or more metal straps arranged in parallel, one sides of the metal straps are connected with the outer protection layerin a welded mode, and the other sides of the metal straps are in nailed or riveted connection with the inner protection layer. The outer protection layer is evenly provided with concave-convex parts,that is, pits are formed in one side of the outer protection layer, protrusions corresponding to the pits are arranged on the other side of the outer protection layer, and joints of the two ends of the outer protection layer are connected in a welded mode. By means of the heat insulating structure of the pipeline, the step of manually wrapping the pipeline with the inner protection layer is omitted, time is shortened, the assembly efficiency is improved, the assembly cost is reduced, and meanwhile the product quality is ensured.

Description

technical field [0001] The invention relates to a thermal insulation structure, in particular to a pipeline thermal insulation structure. Background technique [0002] Existing pipeline insulation generally uses insulation materials wrapped outside the pipeline. The commonly used wrapping method is to first cut the insulation material to match the size of the pipeline, and then fix the insulation material with high-temperature cloth by manual wrapping. , the outer side of the high-temperature cloth is fixed by stainless steel materials; due to many irregular pipelines, the manual wrapping process is time-consuming and long, resulting in not only complicated procedures during the installation of this structure, but also high difficulty in operation, especially the use of high-temperature cloth for heat insulation materials During fixing, it is easy to have uneven wrapping on the outer wall of the pipeline, resulting in poor cooling effect. Therefore, this structure has the p...
