[0002] A pipeline generally refers to a pipeline that transports liquid and gas materials. According to the type of the transported medium, the oil and gas pipeline can be divided into crude oil pipeline, refined oil pipeline, oil and gas mixed pipeline, etc. In winter, due to the cold weather, if the insulation effect of the oil and gas pipeline is poor, it often causes scaling of the pipeline. In order to avoid scaling of the oil and gas pipeline in winter, the pipeline needs to be heated. Without destroying the overall structure of the pipeline, the heating equipment can be connected to the outer wall of the pipeline to heat the oil and gas in the pipeline.

[0003] The existing pipeline heating device is directly wrapped and fixed on the outside of the pipeline for heating treatment, which makes it difficult for the same heating device to perfectly adapt to pipelines of different diameters, affecting the actual use convenience and adaptability of the pipeline heating device.
