The atmospheric pressure storage tank shows signs of tilting
Thread Content
Dear friends, please clarify: since the atmospheric pressure storage tank shows signs of tilting, what precautions should be taken during its use? To what extent is the use prohibited?
Since signs of tilting have been observed, use should be stopped immediately, the material removed, the cause identified, measures taken, and then use resumed. Under no circumstances should one give up until the worst happens, causing even greater accidents
Since there are signs of tilt in the observations, actual measurements must be carried out to confirm it. If a tilt indeed exists, its cause must be identified before deciding whether to continue monitoring and using it.
Testing has been scheduled for the next step. Under what circumstances can it be used for monitoring, and when should its use be stopped?
It’s not possible to give a simple opinion on this; it needs to be determined based on the specific test results – is it due to issues with the foundation? Is it due to the structure of the tank itself? Are there any other situations? Judgments are made based on a analysis of specific circumstances and predictions regarding the development trend of the situation.
It should be immediately shut down and its use prohibited.
If it is a problem related to the foundation, then it is necessary to consult experts in civil engineering to determine whether remedial measures can be taken to strengthen the foundation, or whether the storage tank cannot be used anymore It must be demonstrated by professional institutions and experts.
Once it has been discovered, it should be immediately shut down and its use prohibited.
Reference can be made to the API653 standard, which includes specifications for measuring inclination as well as the allowable degree of inclination. It is advisable to have professionals conduct inspections, and subsequent actions can then be determined based on the results of those inspections.
The visible tilt indicates that the situation is already serious; the material should be emptied and the cause identified. In most cases, the issue lies in the foundation; if it’s an area affected by corrosion, it’s best to check what’s underground.
