Description

Technical Field

[0001] The utility model relates to the technical field of pipeline insulation, in particular to an outdoor pipeline insulation sleeve. Background Art

[0002] Outdoor pipelines, including oil pipelines, natural gas pipelines, heating pipelines and water pipes, are used to transport some media. Some pipelines can also withstand certain high pressures and high temperatures. Pipelines made of special materials are also corrosion-resistant and can transport some special media. These pipelines provide great convenience for industrial production and people's lives.

[0003] During the use of these outdoor pipelines, especially in the cold winter period or extremely cold areas, the transportation medium in the pipeline will be affected by the low temperature, resulting in a slow transportation speed and the transported raw materials losing temperature and freezing. Secondly, good sealing is required between the external insulation equipment to better prevent rainwater from entering between the insulation equipment and the pipeline and affecting the pipeline. Finally, during the protection of the pipeline by the insulation equipment, more ice may freeze on the outside, increasing the deadweight of the pipeline and the insulation equipment. The distance between the pipeline bearing columns is far, and it cannot provide a good support for the pipeline and insulation between the bearing columns. Therefore, an outdoor pipeline insulation cover is proposed to address the above problems. Utility Model Content
