Electric Pipeline Heater For Even Heating Closed Environment Pipeline

Even Heating and Closed Environment Pipeline Use Electric Heater is made up of several MI heating cables, barrels and guide plates. Electric MI heating element is a heating cable with a metal sheath insulated with compact magnesium oxide cylinders with extreme good properties on insulation and thermal conduction compared to conventional electric heating tube. Therefore, the electric heating element, compared to conventional heating tube, has advanced structure, high thermal efficiency, good mechanical strength, corrosion resistance, abrasion resistance, etc.

The barrel body is equipped with a diversion baffle, which can make the gas and liquid heat evenly during the circulation.

Two, the characteristics of the Even Heating and Closed Environment Pipeline Use Electric Heater

Pipe type electric heater belongs to an electric heating device used for heating pipes or the medium inside them.

Through the conveying system, the liquid entering the pipe electric heater is discharged at high temperature and high pressure.

After heating, the liquid is still in a closed environment. It has good explosion-proof, and is widely used in heating oil, air, heavy oil, asphalt, clear oil, steam and other fuel oil.

It has the advantages of high thermal efficiency, convenient installation and disassembly, and is widely used in various pipe heating occasions.

Structure and working principle

1. Structure

The electric heater structure consists of nine parts. (See Figure 1)

2. Working Principle

The cold medium enters the diversion chamber through the oil inlet, so that the medium flows into the mixing chamber along the periphery of the heating element, and the mixed medium flows out from the oil outlet at a uniform temperature. The mixing chamber is equipped with a temperature measuring sensor, and the temperature signal is collected and transmitted to the electronic control system. The temperature control instrument controls the primary circuit to realize automatic control of the oil temperature. When the oil products or electric heating element of the heater is overheated, the protection device automatically cuts off the power supply and the control cabinet emits an audible and visual alarm signal.
