Tubular heaters are often used for heating air, liquids, gases and solid body.
Tubular heating element are capable of using three different way to heat: conduction heating, convection heating and radiant heating.
It is the most versatile heating appliance among all electric heating elements.
Tubular heater consists of helical resistance wire and metal sheath. The wire is often made of nickel and chromium.
The alloy resistance wire is centered in the metal sheath, which is filled with Magnesium Oxide Power (MgO).
The MgO powder has a very good dielectric strength and provide uniform heat from the coil to surface of metal sheath.
Annealing is necessary to make the tubular metal soft and able to be bent into virtually any shape.
