Precautions for Explosion-Proof Flange Heating Pipe

Precautions for Explosion-Proof Flange Heating Pipe

1. The heating tube must be completely immersed in the heating oil to avoid burning out the heating tube components, and the heating oil should be non-corrosive;

2. The working fluid level must be below the fastener and above the dimension line B;

3. When melting bitumen, paraffin and other solid oils, the voltage should be lowered for use, and then raised to the rated voltage after melting. To prevent the power concentration from reducing the service life of the components;

4. When carbon buildup is found on the surface of the pipe, it must be removed as soon as possible to avoid reducing the heating efficiency; electric air heater

5. The components should be stored out of dryness. If the insulation resistance drops below 1 megohm due to long-term storage, they can be dried in an oven of about 200? for a few 1-2 hours (or pass the components under low pressure for several hours). That is, the insulation resistance can be restored.

There are generally several principles to follow in the use of electric heating tubes:

1. Fully understand the environment in which the electric heating tube is used, whether it is medium conduction or infrared radiation. 2. Fully understand the temperature requirements of the electric heating tube, and choose an electric heating tube with a suitable power. Generally, the power is large, the heat is fast, and the temperature rises quickly, and vice versa.

3. Select the electric heating tube of the appropriate power, and pay attention to the power load problem under the premise of ensuring the effective use of temperature requirements.

4. Dry-burning electric heating pipes should pay special attention to the heat dissipation effect of the use environment, which is divided into static air and flowing air.
