Heater Tubes
Heater tubes generally refer to tubes used in industrial heating applications. These tubes are typically made of metal alloys and are resistant to high temperatures. Heater tubes are used to produce heat with electrical energy. An electric current is passed through the tube, and the resistance within the tube converts electrical energy into heat. Heater tubes are used in many industrial applications such as industrial furnaces, boilers, heating systems, plastic extrusion machines, injection molding machines, and more. They are particularly important for maintaining temperature stability in process control. Heater tubes can be found in various shapes, sizes, and materials, providing flexibility to meet different application requirements. The selection of these tubes is made based on the requirements of the application, the working environment, and the heating process.Pipes for Heating Elements

Heater Tubes Working Principle
- Application of Electric Current: Electric current is applied to heater tubes from a source. This current passes through the tubes.
- Resistance and Heat Generation: Heater tubes typically consist of a resistance wire. As electric current passes through this resistance wire, the resistance converts electrical energy into heat energy. The resistance generates heat inside the tube.
- Heat Transfer: The outer surface of the tube transfers the heat generated inside to the external environment. Thus, heater tubes are commonly used for heating a process or maintaining the temperature of a specific environment.
- Control and Regulation: The heat generation is controlled, usually using a thermostat or another control device. This ensures the maintenance of the desired temperature range.

Heaters Tubes Types
- Straight Heater Tubes: Straight heater tubes, which have a simple design, are typically used in air and liquid heating systems. They consist of a resistance wire passing straight through the tube.
- Finned Heater Tubes: Finned heater tubes have a wavy shape on the surface of the tube. This corrugated structure increases the surface area of the tube, allowing for more heat transfer. These tubes are often preferred in high-density heating applications.
- Coiled Heater Tubes: Coiled heater tubes are tubes where a wire is wrapped around the tube. Because of their larger surface area, these tubes increase heat transfer and efficiency. They are commonly used in industrial furnaces and process heating systems.
- Flexible Heater Tubes: Flexible heater tubes can be produced in different shapes and lengths due to their bendable and flexible structures. This flexibility allows the tube to be mounted and adapted in certain shapes. Flexible heater tubes are especially preferred in heating applications with complex geometries.
- Titanium-Coated Heater Tubes: Titanium-coated heater tubes are preferred for their resistance to high temperatures and corrosive environments. Titanium coating extends the life of the tube and provides resistance to corrosion. These tubes are typically used in the chemical industry and heavy industrial applications.
