Description

Technical Field

[0001] The invention relates to the technical field of oil and gas pipelines, in particular to an anti-corrosion water mist cooling device for oil and gas pipelines. Background Art

[0002] Oil and gas pipeline transportation has emerged along with the development of the petroleum industry. There are many types of oil and gas pipelines, and the classification methods are different. For example, according to the length and operation mode, oil and gas pipelines can be divided into pipelines inside oil fields and long-distance oil and gas pipelines; according to the type of the transported medium, oil and gas pipelines can be divided into crude oil pipelines, refined oil pipelines, natural gas pipelines, oil and gas mixed pipelines, etc.; according to the location of the pipeline, oil and gas pipelines can be divided into onshore pipelines and submarine pipelines, etc.; after transporting hot oil, the temperature of existing oil and gas pipelines is difficult to drop in a short time. Since the temperature inside the oil and gas pipelines is too high and there is more contact with the air, corrosion will be accelerated, further reducing the life of the pipeline.

[0003] A Chinese patent discloses an anti-corrosion water mist cooling device for oil and gas pipelines (authorization announcement number CN211232042U).
