The design is a container outside the category; we now want to use it as a pressure vessel. What should we do to obtain the necessary permits in the absence of relevant documentation?
The design specifies that containers outside this category cannot be used as pressure vessels.
How is it possible to apply for certification as a pressure vessel when it wasn’t manufactured as one, and there’s no relevant documentation either?
It’s not possible; there’s really no way around it – one has to buy a new one
No, it’s necessary to create another one from scratch
No, with such strict checks being carried out these days, it can’t be used even for one’s own safety.
You can convert pressure vessels that have not reached their end-of-life date or those for which an extension for use has been granted into atmospheric storage tanks, but it’s absolutely impossible to use such atmospheric storage tanks as pressure vessels – don’t even think about it. No one will provide you with the necessary documents or procedures for that.
Safety first; think more about yourself
Something that’s not a pressure vessel is simply not a pressure vessel; it wasn’t designed as one from the very beginning. If upgrading the class is truly necessary, then starting from the design phase, all relevant processes must be gone through. Design section: It is necessary to conduct a strength check on all components again, using the current actual parameters. If the medium is harmful, then component replacement may also be required. Material section: Since there is no relevant data, there is certainly no warranty certificate either; therefore, it is necessary to conduct tests to determine the nature of the tank material. Inspection section: Non-destructive testing – 100% coverage is clearly required here, and all welds and the like need to be checked as well. Inspection section: The local special inspection agency gives its approval and provides a written response. If the device is not large and the materials are ordinary, following the above process is likely to end up being more expensive than buying one directly. Only equipment made of special materials and of great value is worth such treatment.
