How to repair tower perforations
Thread Content
I would like to ask everyone how to repair a tower with perforations after it has to be shut down
Repairing is simple. The problem lies in the preliminary preparation work; it is quite difficult to ensure absolute safety. After cleaning and displacement, water is injected at the repair location; the upper part of the tower is protected with nitrogen. The operation should not last too long and can be carried out in intervals, with inspections required after each session.

Generally, the perforations in tower bodies are quite small; when the temperature of the medium inside the tower is high, it can be difficult to locate these perforations even after the tower is shut down； First, park the vehicle and clean it thoroughly, then use the ammonia infiltration method to detect leaks and locate the source of the leakage ； The second step is to carry out patch welding based on the material of the tower; argon arc welding is generally used for this ；
