Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pipelines, and in particular to a pipeline anti-corrosion and thermal insulation structure. Background Art
[0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles. It is connected by pipes, pipe connectors and valves. Pipelines are widely used in modern life. They are not only used for water supply, drainage, heating and gas supply, but also for long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects and various industrial installations.
[0003] When a pipeline is transporting a fluid medium, due to environmental factors and the corrosiveness of the medium itself, both the inner and outer walls of the pipeline will be corroded. At the same time, during the transportation process of the pipeline, due to the temperature difference of the fluid medium, heat loss will occur. Therefore, pipeline anti-corrosion and thermal insulation are important issues in pipeline engineering. Existing pipeline anti-corrosion and thermal insulation technologies usually use a single anti-corrosion layer or thermal insulation material, but this method often cannot meet the requirements of anti-corrosion and thermal insulation at the same time, and the service life is short;
[0004] In order to solve the anti-corrosion and thermal insulation problems of pipelines, an anti-corrosion layer is usually coated on the outer wall of the pipeline, and then an insulating material is wrapped outside the anti-corrosion layer. However, this method has the problem of insufficient adhesion between the anti-corrosion layer and the thermal insulation material, which is easy to fall off. At the same time, the performance of the anti-corrosion layer and the thermal insulation material will gradually decline over time. Utility Model Content

[0012] Furthermore, the reflective layer is bonded to the heat insulating layer, and the reflective layer is aluminum foil.
[0013] Through the above scheme, the heat emitted by the main pipeline can be reflected by setting the aluminum foil material, which is beneficial to improving the thermal insulation effect of the pipeline.
[0014] Furthermore, the reflective layer is bonded to the noise reduction layer, and the noise reduction layer is made of glass fiber material.
[0015] Through the above scheme, the glass fiber material not only provides good sound insulation effect, but also is resistant to high temperature, and can improve the overall sound insulation.
[0016] Furthermore, a plurality of air isolation cavities are provided inside the noise reduction layer, and the plurality of air isolation cavities are distributed in a circular pattern.
[0017] Through the above solution, the air isolation cavity can help improve the sound insulation performance and reduce the propagation of sound.
[0018] Furthermore, the noise reduction layer is bonded to the sound absorbing layer, and the sound absorbing layer is made of sound absorbing cotton.

[0021] Through the above scheme, installing multiple insulation cottons can improve the insulation performance of the main pipeline and reduce the loss of medium temperature in the main pipeline.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] The pipeline anti-corrosion and thermal insulation structure can simultaneously meet the anti-corrosion and thermal insulation requirements of the pipeline by arranging an anti-corrosion layer and a thermal insulation layer, thereby improving the service life and energy utilization efficiency of the main pipeline. At the same time, the adhesion between the anti-corrosion layer and the thermal insulation layer is improved, thereby avoiding the occurrence of falling off. By installing elastic shock-absorbing parts, the vibration generated during the flow of the medium can be reduced, thereby improving the service life of the main pipeline, reducing the heat loss of the main pipeline during the transportation process, and improving the energy utilization efficiency.
