Is it feasible to convert a fixed-roof storage tank into a steel single-disk, fully submerged floating roof storage tank?
Thread Content
In accordance with environmental requirements for VOC control, it is planned to convert a 30,000 m3 fixed-roof diesel storage tank into an internal floating-roof tank. A single-plate, fully submerged floating roof made of steel is considered for use, with the assembly and welding to be carried out inside the tank. Is this approach feasible? If feasible, what issues should be considered when working inside the storage tank?

There are versions for series 1 to 5; check if any of them are useful. It’s best to solve problems in a way that is based on standards and evidence.
Safety first; at least diesel is not poisonous.
Sure, it is necessary to pay attention to the requirements that the floating disc sealing design imposes on the tank wall and welds; you can add q494079174 to discuss this further
It can be modified into an internal floating roof tank, which involves hot work inside the tank; care must be taken to ensure thorough purging and blanketing as well as to maintain safety during hot work.
