How many guidelines should be followed normally for the use of single-head tubes:

1. Fully understand the operating conditions of the single-head tube, whether it is medium propagation or red inner line radiation.

2. Fully understand the application heat of the single-head tube, and choose a single-head tube with suitable power. Under normal conditions, the power is large, the heat is fast, and the pressure rises quickly, and vice versa.

3. Choose a single-head tube suitable for the power, and pay attention to the power load problem under the premise of ensuring the ineffective use of heat.

4. Dry-burning electric heating pipes should pay special attention to the heat dissipation motives of the operating conditions, which are divided into static atmosphere and fixed atmosphere.

5. Dry heating of water-heated electric heating pipes is strictly prohibited, especially electric heating pipes used in immersion type.
