In addition, the electric tracing band has very high energy consumption, is easy to age and needs to be replaced in time. The heat exchange accompanying pipe is also a common mode for realizing heat exchange of the pipeline, and adopts the mode that an accompanying pipeline communicated with a heat exchange medium is arranged on the wall of the closely attached main pipeline, and the heat exchange with the main pipeline is carried out to heat or cool the medium in the main pipeline. The mode is characterized in that the inner pipe is mainly used for exchanging heat with the fluid of the main pipeline, and the inner part of the outer layer pipeline (the jacket) is internally communicated with the heat exchange fluid.
