For a internal floating roof tank, there is oil leakage at a strip weld on the roof plate – what should be done?
Thread Content
There is an oil leakage at a strip weld on the top plate of the tank, over a length of about 100 mm. The medium stored in the tank is fuel oil. Is it possible to carry out welding work now? Are there any other methods?
Under no circumstances should welding be used; if emergency repair is necessary, consider using temporary adhesive sealing instead.
When performing hot work, it is necessary to ensure that the fuel oil inside the tank is properly boiled, blind plates are installed, and the air is replaced. Obtain the hot work permit and confined space operation permit properly.
I made a mistake; it’s an external floating roof tank. What adhesive should be used for sealing it?
We can’t use fire; let’s think of other ways
Working with fire in this environment is very dangerous; oil and gas will definitely evaporate from the welds
If there’s a leak, just fix it; working with fire can easily lead to accidents!
