Description

Technical Field

[0001] The utility model relates to the field of temporary heating and insulation of pipelines in petrochemical enterprises, in particular to a heating and insulation blanket. Background Art

[0002] In the petrochemical, energy, food and other industries, insulation and heating of pipelines and equipment are important links to ensure production efficiency and safety, especially in extremely cold weather or temporary changes in process conditions. Some pipelines that were originally designed without heating and insulation need to add temporary heating and insulation. Although traditional electric heating or electric blankets can meet the needs to a certain extent, there are great safety risks when used in flammable and explosive medium pipelines. For example, damage to the cable sheath may cause contact with flammable and explosive media, thereby causing safety accidents. In addition, although adding a formal steam or hot water heating system is safer, the construction period is long, and it cannot be reused after use, resulting in a waste of resources.

The corrugated pipe is used to transport the heat source to conduct heat to the pipeline. Two connectors are provided. The two connectors are respectively arranged at the two ends of the corrugated pipe. The connector is used to be threadedly connected with other pipelines. Several groups of splice buckles and splice sleeves are provided. Each group of splice buckles and splice sleeves are respectively arranged on both sides of the blanket body. Each group of splice buckles and splice sleeves can be mutually aligned and spliced. The splice buckles and splice sleeves are used to connect and fix the two sides of the pipeline when the blanket body wraps the pipeline.

[0021] It should be noted that: the bellows 2, as a channel for heat source transmission, can evenly transport heat sources such as steam or hot water to the inside of the blanket body 1 through a continuous bending design.
