U-shaped tubular heating element Flange Electric Heating Tube

Flange Electric Heating Tubes
Flange electric heating tubes are industrial electric heaters that utilize a U-shaped tubular heating element secured to a flange. These elements are inserted into tanks, containers, or piping systems via flange connections or threaded seals. They are used to heat and insulate liquids, gases, and other media. These devices offer a compact design, high thermal efficiency, safety, and reliability, along with integrated temperature control and interlocking protection systems. They are widely used in the petroleum, chemical, food, and machinery industries.

Structure and Principle

Composition: Flange electric heating tubes consist of a U-shaped tubular heating element, a flange cover, a filler (such as magnesium oxide powder), and a heating wire.

Installation: Multiple U-shaped heating tubes are secured to the flange cover using argon arc welding or fastening devices, and then the flange is sealed to the connection port of the container or pipeline.

Operating Principle
When the heating element is energized, it generates heat. The heat generated is transferred through the metal tube wall to the heated medium, raising its temperature to the desired process temperature.

Key Features
Efficient and Concentrated Heat Source
1. The densely packed U-shaped tubular heating elements provide high thermal efficiency and a concentrated heating range.
High Safety
2. Often equipped with interlocking protection devices such as over-temperature and low liquid level protection devices, which cut off power to prevent damage.
Easy Maintenance
3. Some flanged electric heating elements are designed to allow individual replacement of individual heating elements, facilitating repairs.
High Automation
4. Integrate temperature sensors and PID control systems for automatic temperature and power regulation.
Compact Structure
5. No additional brackets are required, enabling a highly compact design.

Applications
Flanged electric heating elements are widely used in industrial applications requiring heating and insulation:

Petrochemical Industry
1. Heating of media such as storage tanks, containers, and pipelines.

Food Processing
2. Heating and insulation of storage tanks and containers.

Machinery Manufacturing
3. Heating of circulation systems, mold temperature controllers, etc.

Other Industries
4. Applications such as water tanks, oil tanks, reactors, and thermal oil tanks.
