China Enamel glass thermowell

China enamel glass thermowell may cause some damage to equipment due to improper use or other issues, and the reactor itself is usually larger in size. If it is very troublesome to transport it back to the factory for maintenance, let's have a detailed understanding of what needs to be done for on-site maintenance.

1. When the metal substrate is severely corroded or even penetrated, repair welding should be carried out immediately, and full penetration operation should be carried out as much as possible, and intermittent welding should be used. When the temperature of the China enamel glass thermowell around the welding position is detected to be too high, welding should be stopped and corresponding cooling measures should be taken. Welding should continue after the enamel has cooled down. Otherwise, when the glass lining layer is welded, there will be a large area of porcelain bottle explosion. After welding, it is necessary to conduct a hydrostatic test on the reaction vessel.

2. After welding repair, the reaction kettle often needs to be left for 2-3 days for surface treatment. It is necessary to use a grinding machine to clean the weld area and polish the metal surface. When repairing, ensure that the surface of the China enamel glass thermowell is in a clean state. The materials and techniques used during the repair process have a significant impact on the repair effect.
3. When repairing, two or more people need to operate, one of whom needs to repair inside the tank and the other needs to monitor outside the tank.
The above introduces the on-site maintenance work of China enamel glass thermowell. When repairing the internal glass lining, it is usually necessary to choose a suitable repair method based on the size of the damaged area. For example, some methods used to repair large areas are different. Only in this way can we ensure that it will not come off again after use.
