High temperature resistant thermal oil electric heating rod

The most commonly used types of high-temperature thermal oil heaters are threaded and flanged.

When designing a high-temperature thermal oil heater, use threaded heaters for power below 5 kW.

For power above 5 kW, use flanged heaters.

High-temperature thermal oil heaters can be made from the appropriate heat-resistant material based on the operating temperature:

For operating temperatures exceeding 300°C, use 321 stainless steel, which has a heat resistance of 500°C.

For operating temperatures exceeding 500°C, use 310S stainless steel, which has a heat resistance of 700°C.

Installation Precautions for High-temperature Thermal Oil Heaters:

When installed horizontally, the external pipe section of the high-temperature thermal oil heater should be designed as a cool zone. This area has less oil and absorbs more heat, making it more susceptible to burnout.

If installed vertically, places without liquid should be made into cold areas to avoid dry burning and damaging the high-temperature resistant thermal oil electric heating rod.
