Heat Treatment of Power Plant Main Steam Pipe

The main gas pipeline in the power industry needs to be overhauled after a certain period of use. As the main gas pipeline is welded and repaired, a process that must be passed through is heat treatment to achieve the purpose of eliminating stress and strengthening the weld. The pipeline heat treatment heating equipment used by our company can set the heating temperature, heating time, and holding time according to the temperature rise curve. Compared with the traditional ceramic sheet, the heating efficiency is higher. Because the induction heating is used to make the metal heat itself, and the electromagnetic wave has a certain penetration ability, the entire heating is more uniform, and the heat treatment effect is far better than that of the ceramic sheet. Heating.

Advantages of induction heating:

1)The induction heating has a fast heating speed. Compared with the traditional ceramic sheet heating, due to the large energy density, the heat treatment time period can be shortened, and the work efficiency can be improved to a certain extent.

2)The energy of induction heating can penetrate the surface of the workpiece to the inside of the metal, which can reduce the temperature difference between the core and the surface to a large extent.

3)The advantages of induction heating under the working conditions of large pipe diameter and large wall thickness can be more prominent.

4)The induction heating temperature is uniform.

5)The temperature controllability of induction heating is better, closed-loop temperature control and temperature curve collection can be realized, and the processing parameters can be intelligent.
