Thermal engineering buried insulation pipeline
With the acceleration of urbanization in China, the quality and safety of thermal engineering, as an important part of urban infrastructure, have received extensive attention. In thermal engineering, buried insulation pipelines are a key component, and their performance and quality directly affect the operation effect of thermal engineering. This article will introduce the overview, advantages, design and construction methods and maintenance of buried insulation pipelines, in order to provide reference for relevant engineering and technical personnel.
1. Overview of buried insulation pipelines.
Buried insulation pipeline is a kind of pipeline that lays insulation materials on the outer wall of the pipeline to achieve the insulation effect. It is mainly composed of steel pipes, insulation layer and protective layer, of which the insulation layer is usually made of polyurethane foam, glass fiber and other materials. Buried insulation pipelines are mainly used in heating, refrigeration, oil transportation, steam transportation and other pipeline projects, which can effectively reduce heat loss, improve energy efficiency, reduce pipeline corrosion and scaling, and prolong the service life of pipelines.
Second, the advantages of buried insulation pipelines.
1.Energy saving and environmental protection: The use of insulation materials can effectively reduce heat loss, reduce energy consumption, and reduce the impact on the environment.
2.Reduced corrosion: Insulation protects the outer wall of the pipe from soil and water, reducing problems such as corrosion and scaling.
3.Extend service life: The use of insulation materials can reduce the frequency of repairs and replacements of pipes, and extend the service life of pipes.
4.Simple construction: the installation and construction of buried insulation pipelines are relatively simple, which can shorten the construction period and reduce the project cost.
3. Design of buried insulation pipelines.
In thermal engineering, the design of buried insulation pipelines should be carried out according to specific engineering requirements and pipeline parameters. Factors such as the diameter, length, conveying medium, operating temperature and pressure of the pipeline, as well as the supporting structure of the pipeline, soil conditions and the performance of the insulation material need to be considered in the design. In the design process, professional design software should be used for simulation and analysis to ensure the rationality and reliability of the design.
Fourth, the construction method of buried insulation pipeline.
1.Preparation before construction: Pipes and insulation materials should be inspected and accepted before construction to ensure that their quality and specifications meet the design requirements. At the same time, the construction site needs to be cleaned and leveled to prepare for construction.
2.Pipeline installation: Install the pipeline according to the design drawings and requirements, ensure that the position and elevation of the pipeline meet the design requirements, and also need to fix and support the pipeline to prevent it from shifting or deforming.
3.Insulation laying: After the installation of the pipeline is completed, the insulation material should be laid on the outer wall of the pipeline, and ensure that it is flat, uniform and seamless. For different insulation materials, the laying method is also different, and the construction should be carried out according to the requirements of the material.
4.Protective layer construction: After the insulation layer is laid, the construction of the protective layer should be carried out to protect the insulation layer from external factors. The protective layer can be constructed with waterproof coatings, waterproof membranes and other materials.
5.Acceptance and commissioning: After the construction is completed, the buried insulation pipeline should be accepted and debugged to ensure that its performance and quality meet the design requirements. At the same time, it is also necessary to summarize and evaluate the construction process, summarize lessons learned, and improve the construction quality.

Maintenance of buried insulation pipelines 1In the process of use, the buried insulation pipeline should be regularly inspected and maintained, and the damage or aging should be repaired or replaced in time. 2.Care should be taken to avoid excessive pressure or temperature fluctuations on the pipes during use to reduce damage to the insulation material and protective layer. 3.During use, attention should be paid to keeping the surrounding environment of the pipeline dry and clean to prevent damage to the pipeline caused by moisture and corrosive substances in the soil.
