Overview and working principle of flange heating pipe

        Flange electric heating pipe (also known as plug-in electric heater): it adopts U-shaped tubular electric heating element, which is assembled on the flange cover according to the design specifications of different heating media and the power configuration requirements, and is inserted into the materials to be heated. A large amount of heat generated by the heating element during operation is transmitted to the heated media to raise the medium temperature and meet the required process requirements. When the medium temperature reaches the set point of the process requirement, the control system adjusts the output power of the electric heater according to the temperature sensor signal after PID operation, and realizes the temperature control for the resistive load of the heating element. Make the medium temperature uniform and meet the required requirements; When the heating element is over temperature or low liquid level, the interlocking protection device of the heating element immediately cuts off the heating power supply to avoid burning out of the heating element and prolong the service life.

        Application scope of flange electric heating pipe

        Flange heating pipe is mainly used for insulation and heating of various storage tanks, containers and materials in oil tanks in petroleum, chemical, food, machinery and other industries. Flange type or threaded end face seal can be used for connection

        Performance and use

        1. The flange heating pipe is welded on the flange by multiple heating pipes for centralized heating. It is mainly used for heating in open and closed solution tanks and circulating systems.

        2. Advantages: high surface power, 2 ~ 4 times of air heating surface load, highly dense and compact structure. As the whole is short and dense, it has good stability and no support is required for installation.

        3. Most of the combined flange heating pipes adopt argon arc welding to connect the electric heating pipe with the flange, or in the form of fastening device, that is, fasteners are welded on each electric heating pipe. Then lock with the flange cover with nuts. Argon arc welding shall be adopted for pipes and fasteners to avoid leakage. The sealing part of fasteners adopts scientific technology. It is very convenient to replace a single one, which greatly saves the maintenance cost in the future

Select imported and domestic high-quality materials. Scientific production technology and strict quality management ensure the superior electrical performance of electric heating tube.

        4. According to the special use requirements of customers, the heating pipe can be desalted, so that the internal insulating heat conductor (magnesia powder) of the heating pipe can be completely crystallized and will not be carbonized for a long time, so as to prolong the service life of the heating pipe.

        Scope of application: flange electric heater is mainly used for insulation and heating of various storage tanks, containers and materials in oil tanks in petroleum, chemical, food, machinery and other industries. Flange type or threaded end face seal can be used for connection.
