Regarding the duration of tank cleaning
Thread Content
I would like to ask how long it generally takes to clean storage tanks during inspection and maintenance. Is the cleaning time the same for tanks of different sizes? Are the cleaning times for spherical tanks and atmospheric storage tanks the same?
This question is too general – the medium of the container? Deposited debris? The appropriate cleaning methods and such need to be clarified.
It depends on the medium in your storage tank, the cleaning method, and the intended use after cleaning. If there are certain materials that are sensitive to odor transfer. It needs to be taken in for maintenance; ordinary cleaning is not sufficient – steaming is also required. So it depends on your actual use case.
For example, in the case of aviation fuel, it depends on the tank bottom structure; in China, it is generally two years. Other finished gasoline and diesel tanks are generally around 4 years, I guess
LPG storage tank, cleaned with water; cleaning is done during shutdown for maintenance. How long does it take approximately?
Perhaps you are making plans; most of these types of maintenance tasks involve the maintenance of interconnected systems. Check the maximum maintenance time allowed for other projects, and use that maximum time as the value you report. Then, during the maintenance process, the actual time required is taken into account to determine the schedule for the next maintenance session. Regarding the issue, you say to wash it with water, but how exactly is that to be done? For example, should an access hatch be installed? Should a replacement be done? Pressure testing after sealing the manhole,,,,。 All of this takes time. If the tank is extremely large, is it necessary to set up scaffolding inside the tank???? Your question is very simple, but accurate answers can only be given if you provide relevant data. It’s just for reference.
Medium, material, and conditions inside the tank, as well as washing with water or steam, steam purging, etc
