Overview of tubular heater:

A tubular heater is a seamless metal tube (carbon steel pipe, titanium pipe, stainless steel pipe, copper pipe) filled with electric heating wires, and the gap is tightly filled with crystalline magnesium oxide with good thermal conductivity and insulation. The tubular heaters are connected to the power supply through two lead out rods, and the gap is filled with magnesium oxide powder with good thermal conductivity and insulation, which is then shrunk into various shapes that users need.

Features of tubular heater:

Simple structure

High thermal efficiency

Good mechanical strength

Good adaptability to harsh environments

Tubular heater application:

Heat storage boiler

Thermal storage brick

Atmosphere furnace

Electric heating

Saltpeter tank

water tank

Oil tank

Acid alkali tank

Fusible metal melting furnace

Air heating furnace

Drying furnace

Drying box

Hot pressing molds and other devices.

Precautions for using tubular heater:

1. The components should be stored outside in a dry place. If the insulation voltage drops below 1 megohm due to long-term storage, they can be dried and exploded in a supply box at around 200 ° C for several hours (or the components can be low-voltage for several hours), that is, the insulation resistance can be restored;

When carbon deposits are found on the surface of the pipe, they must be completely removed before reuse to avoid reducing efficiency or even burning out the components:

3. When melting solid oils such as asphalt and paraffin, the voltage should be reduced before increasing to the rated voltage after melting to prevent the concentration of electricity from reducing the service life of the components.
