Whether you need a standard tubular heating element or a customized heater designed according to specific voltage, wattage, dimensions, sheath material, shape, or operating conditions, Indian Heat Corporation provides industrial heating solutions tailored to your application.
A tubular heater is an electric resistance heating element consisting of a resistance wire enclosed inside a metal sheath and electrically insulated using a high-quality insulating material such as magnesium oxide (MgO).
When electrical current passes through the resistance wire, electrical energy is converted into heat. The generated heat transfers through the insulation and outer metal sheath to the surrounding medium.
Depending on the heater design, tubular heating elements can be used for heating:
Air
Water
Oil
Chemicals
Gases
Metal surfaces
Industrial ovens
Process equipment
Tubular heaters can be manufactured in straight, U-shaped, W-shaped, circular, spiral, or customized configurations, making them suitable for diverse industrial heating applications.
The working principle of a tubular heater is based on electrical resistance heating, also known as Joule heating.
The process can be understood in four simple stages:
Electrical current flows through the internal resistance wire.
The resistance offered by the heating wire converts electrical energy into thermal energy.
The generated heat passes through the electrically insulating material surrounding the resistance wire.
The metal sheath transfers the generated heat to air, water, oil, chemicals, or the surface that needs to be heated.
The heater's performance depends on factors including watt density, sheath material, operating temperature, heating medium, airflow, liquid properties, and installation method.
Tubular heaters are among the most versatile industrial heating elements because a single basic heating technology can be adapted for numerous applications.
Major benefits include:
High thermal efficiency
Compact construction
Reliable heat transfer
Customizable shapes
Multiple sheath material options
Resistance to demanding operating environments
Suitable for air, liquid, and surface heating
Easy integration into industrial equipment
Different voltage and wattage options
Long operational life when correctly selected and installed
Their flexibility makes tubular heating elements suitable for both standalone industrial equipment and integrated OEM machinery.
Different industrial processes require different tubular heater designs. Choosing the correct type is essential for achieving efficient heat transfer and reliable operation.
Straight tubular heaters are one of the simplest configurations and are commonly used in industrial equipment where direct linear heating is required.

The correct sheath material and watt density should always be selected according to the liquid being heated.
Some industrial machines require specialized heater geometries that cannot be achieved using standard designs.
Depending on manufacturing feasibility, tubular heaters can be customized into:
U shapes
W shapes
Circular shapes
Spiral configurations
Multiple-bend configurations
Custom heaters can be designed according to equipment dimensions and heating requirements.
A typical industrial tubular heating element consists of several important components.
The resistance wire generates heat when electrical current passes through it.
Common resistance heating alloys may include:
Nickel-Chromium (NiCr)
Iron-Chromium-Aluminium alloys
Material selection depends on the heater design and operating conditions.
High-grade magnesium oxide is commonly used to electrically isolate the resistance wire from the metallic outer sheath while supporting heat transfer.
The outer sheath protects the internal heating components and comes into direct or indirect contact with the heating environment.
Depending on the application, sheath materials may include:
Stainless Steel
Incoloy
Copper
Titanium
Other application-specific alloys
Electrical terminals connect the heating element to the power supply.
Terminal configurations can be customized depending on equipment design and installation requirements.
The following table provides general specification options. Final specifications should always be confirmed according to the actual industrial application.
