The common form is external heat tracing and jacketed pipe heat tracing. External heat tracing, also known as parallel steam pipe heat tracing, is to set one or more steam heat tracing pipes on the heat traced part. It is the most commonly used form at present. However, due to thermal expansion, there is usually a certain gap between the heat traced part and the heat tracing pipe, the heat transfer area is small, the heat transfer mode is mainly air convection and heat radiation, and the heat transfer efficiency is low.
