The constant power electric tracing band is divided into parallel electric tracing band and series electric tracing band, which means that the electric tracing band generates heat with a constant power after being energized and does not change with the change of ambient temperature. The heating principle of parallel and series electric tracing tapes is also different: the series constant power electric tracing tape is an electric heating product generated by the core wire, that is, when the current passes through the core wire with a certain resistance, the core wire will send out Joule heat. Due to the resistance per unit length of the core wire and the passing current. It is equal in the whole length, and the heating capacity everywhere is equal. Therefore, it is mainly suitable for heat tracing and insulation of long-distance pipelines.
Electric heat tracing refers to the use of electric energy to heat the element, and the "heat traced body" continuously generates heat. Heat tracing components are pasted on, for example, heat tracing medium pipes and tanks by means of direct laying, return, spiral, winding, etc; After power on, it generates heat, and the generated heat is used to heat the medium in the pipeline or tank. It is used to solve the problems of temperature maintenance, thawing, anticoagulation, antifreeze and thermal insulation in life or production. Common are temperature maintenance of industrial production process, antifreeze of tap water pipeline, antifreeze of solar water heater pipeline, antifreeze and thermal insulation of fire pipeline, snow melting on roof and gutter, anti condensation of oil wellhead or oil rod, etc. It has a wide range of uses, obvious efficiency, energy conservation and environmental protection. Electric heat tracing usually appears in the form of system, which is called "electric heat tracing system". It is mainly composed of heat tracing components (such as heat tracing belt), control equipment (such as control box, temperature controller, etc.), power box, supporting accessories, etc.
