The flange heater is heated by a plurality of U type tubular heater welded on the flange. Mainly used for heating in open, closed solution tanks and circulation systems.
It has the following advantages: The surface power is large, which makes the air heat the surface load 2 to 4 times.
Flange immersion heater
Highly dense and compact. Since the whole is short and dense, the stability is good and the installation does not require a bracket.
Most of the combined type uses argon arc welding to connect the electric heating element to the flanges. It can also be in the form of fastening devices, that is, each of the electric tubuar heater is welded with fasteners. Then lock with the flange cover with a nut. The pipe is welded with argon arc in the fastener and never leaks. The fastener seal is made using a scientific process. Single replacement is extremely convenient, greatly saving future maintenance costs.
Choose imported and domestic quality materials. Scientific production process, strict quality management, and excellent electrical performance of electric heating element.
Overview and working principle
Stainless steel Flange immersion heater (also called plug-in electric heater): U-shaped tubular electric heating element is adopted. According to the heating medium design specification, it is assembled on the flange cover according to the power configuration requirement, inserted into the material to be heated, and the heating element works. The large amount of heat that is emitted is transferred 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.
Application range
The flange heater is 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.
The electric heating pipes produced by the electric heating pipe manufacturers are various. For different electric heating pipes, the performance and the use will be different. In the process of using, some problems should be paid attention to, otherwise the accident will occur. Let us come together. Find out what you need to be aware of:
When heating fusible metal or solid nitrate, bitumen, alkali, paraffin, etc., first reduce the voltage of use, and then increase the rated voltage after the medium is melted.
The positioning should be fixed, and the effective heating zone should be completely immersed in liquid or metal solids. When it is found that there is scale or carbon on the surface of the pipe body, it should be cleaned up and used in time to avoid heat dissipation and shorten the service life.
