High-pressure steam pipeline heat preservation structure and construction method

Abstract

The invention provides a high-pressure steam pipeline heat preservation structure and a construction method.The heat preservation structure comprises a bottom block, a high-pressure steam pipeline, an external heat preservation layer, a strapping tape, a flange and a connecting device, the high-pressure steam pipeline is arranged at the top end of the bottom block, and the external heat preservation layer is fixedly installed outside the high-pressure steam pipeline; compared with a traditional high swallow steam pipeline, the high swallow steam pipeline has the advantages that when the high swallow steam pipeline is used, the heat preservation effect can be guaranteed, meanwhile, it is guaranteed that the thickness of a heat preservation material is not too large, durability is improved, and the situation that gas is generated in the material due to expansion in the long-term use process is avoided; compared with the prior art, thermal resistance reduction caused by operation is reduced, the maintenance cost is saved for an owner in later operation, stable and efficient connection and reinforcement can be conducted on equipment, the pipeline is more stable and efficient in the material transportation process, the overall working quality is greatly improved, and the working efficiency of the pipeline is guaranteed.

Description

technical field [0001] The invention relates to the technical field of high-pressure steam pipelines, in particular to a high-pressure steam pipeline thermal insulation structure and a construction method. Background technique [0002] The high-pressure steam pipeline is a kind of pipeline for the stable transportation of various materials. The pipeline itself has many advantages and can assist the stable transportation of materials. The projects that need to be tested in China directly affect the investment of the project. The external wind speed and temperature in different regions are very different. Especially in the construction project of high pressure steam pipeline in Huaibei, Anhui, there is currently no heat preservation construction method for high pressure steam pipeline specifically for this project. There is no special high-pressure steam pipeline insulation material, which leads to the rapid loss of heat inside the material during the transportation process, s...

Problems solved by technology

[0002] The high-pressure steam pipeline is a kind of pipeline that can stably transport various materials. The pipeline itself has many advantages, which can assist the stable transportation of materials. During the construction of the high-pressure steam pipeline, the heat dissipation and cost of the high-pressure steam pipeline are construction Projects that require key inspections directly affect the investment of the project. The external wind speed and temperature vary greatly in different regions. Especially in the Huaibei high-pressure steam pipeline construction project in Anhui, there is currently no high-pressure steam pipeline insulation construction method specifically for this project. There is no special high-pressure steam pipeline insulation material, which leads to the rapid internal heat loss of the material during the transportation process, so that the material needs to be reprocessed before it can be put into use. Therefore, the existing pipeline itself is not perfect in structure, which makes the overall work quality Decrease, need to spend some additional resources for rework, affecting the overall work efficiency
