Issues regarding the design qualifications for spherical tanks
Thread Content
Our company is an oil field engineering design firm. At present, for pressure vessel design, only pressure vessels of grades D1 and D2 can be designed (the certification has not been renewed). I would like to ask whether it is possible to design spherical tanks as well This spherical tank is a fake one used as a training facility; it is open-top and operates at atmospheric pressure. Is a design qualification specific to spherical tanks required to design it, or should it be designed as a standard atmospheric-pressure device?
How can an open, atmospheric-pressure device be classified as a \"spherical tank\"?
I might not have explained it clearly; it’s essentially a spherical tank, but it’s not designed to bear pressure. Is it possible to design one like that?
Pressure vessel design requires certification, while vessels at atmospheric pressure do not.
If it is made as a teaching model, there is no issue with design qualifications. If it is a “design template” for applying for design qualifications, pressure-bearing design qualifications are required.
Qualified personnel are required for the design and manufacturing of spherical tanks
I feel the same way. I consulted relevant experts yesterday, and it turns out that whether it’s a spherical tank under normal pressure or under pressure, one must have the appropriate design qualifications to create such tanks.
Why can’t it be classified as a spherical tank? Which part does not meet the standard requirements?
Take a look at how the standards for spherical tanks are defined.
If all requirements are met, then a design approval is required, but supervision and inspection are not necessary.
