Overview and working principle of flanged electric heater

- May 24, 2019-

Flanged stainless steel heating pipe (also called plug-in electric heater): U-shaped tubular electric heating element is adopted. According to the heating medium design specifications, it is assembled on the flange cover according to the power configuration requirements, and is inserted into the material to be heated. The large amount of heat emitted during operation is conducted to the heated medium to raise the temperature of the medium to the desired process requirements. When the medium temperature reaches the set value required by the process, the control system adjusts the output power of the electric heater according to the temperature sensor signal, and performs temperature control on the resistive load of the heating element. The medium temperature is made uniform to meet the required requirements; when the heating element is over-temperature or low-level, the interlocking protection device of the heating element immediately cuts off the heating power source to avoid burning of the heating element and prolongs the service life.


Scope of application: Flange type stainless steel heaters are mainly used for heat preservation and heating of various storage tanks, containers and fuel tanks in petroleum, chemical, food, machinery and other industries. The connection method can be flanged or threaded face seal.
