Oil tank leakage
Thread Content
What should be done if an oil tank is leaking? One of our tanks is leaking at the moment, but we don’t know where the leak is. The current approach is to fill the entire tank with water, but we still don’t know what to do next

What material is stored in this tank? What is the capacity of the tank? When was the last time anti-corrosion treatment was done? What type of anti-corrosion coating was used? Where is the oil leak (on the tank wall or at the bottom of the tank)?

Anti-corrosion treatment was applied two years ago, but the type of coating used is unknown. Preliminary investigations indicate that oil is leaking from the bottom, and even in the empty tank after drainage, oil leakage at the bottom was found.
In most cases, cracks appear in the welds, which are caused by welding defects. After several years of operation, these defects expand, leading to oil leakage. The repair method involves carrying out process treatments on the tank; steam can be used for inspecting the bottom of the tank, with 100% MFL inspection of the welds. Based on the inspection results, repairs such as rewelding are carried out.
1# wangyoujin If the specific leakage point cannot be identified, a steel plate can be welded on at that location.
Whether to use pressure testing for leak detection, for reference
Care must be taken when dealing with the bottom; if the damage is not severe, ceramic repair can be used to fix it. However, yours may be severely damaged and require a new base.
OP, I guess the leak is at the bottom of the tank, because the tank walls can be seen! ! ! Conduct a thorough leak check of the tank bottom, paying extra attention to the key areas! ! Then analyze the leakage location and take appropriate measures to resolve it! !
The vacuum chamber method can be used to locate the leak, and once it is found, appropriate repairs can be carried out, but only on the floor.
Use a vacuum chamber to detect leaks, then perform additional welding or use other methods to make repairs. This is the only option
