Can Anyone tell me about code's requirements of burried vessel?
Also please guide about Safety requirements (if any) imposed by NFPA 58.

Adeel,

Nonmandatory Appendix VII of ASME B31.1 gives PROCEDURES FOR THE DESIGN OF RESTRAINED UNDERGROUND PIPING, as far as I know.

Thanks Nasir,
But for Pressure Vessel design of buried vessel should External Pressure be considered?

Please expedite

Adeel,

We experienced a buried vessel before, Our client engineering agency asked for consideration of External pressure due to weight of the sand over the vessel in addition to the external design pressure.

I don't know any applicable rules, but as a mechanical engineer I would discourage from using external hydrostatic scheme, as earth does not act uniformly. You can't even say it's purely load controlled. I would be careful.
