Code or non code question.

Code or non code question.

Code or non code question.

(OP)
I am looking for guidance on an enclosure used to house electronic equipment. The enclosure is a rectangular flanged box with o-ring seals and flat lid. The enclosure will be used to keep the equipment dry while submerged in water to a depth of 60-70 feet. When would this become an unfired pressure vessel and require ASME construction.

RE: Code or non code question.

tom1982, I doubt such a vessel would ever be considered subject to any pressure vessel code, unless it were imposed by the owner.

Code methods could be used in design if one wished, although there might be better ways.

Regards,

Mike

RE: Code or non code question.

ASME Sec VIII, Div 1 exempts vessels whose longest cross section inside length dimension (diameter, side, diagonal, etc) is under 6 inch, no limit on vessel length.

RE: Code or non code question.

My 'read' is that this use is outside of the B&PV intent of ASME, thus 'non-Code'.
*However*, I would use the design rules of ASME Sect VIII Div-1. They are fairly 'readable' and easy to work to.

RE: Code or non code question.

Duwe6, doubt the OP will be happy w/ Appendix 13. I never am :)

Thanks for the replies, I do need to close the loop on this though. This tool will be used in a nuclear plant in the reactor vessel the borated water will be contaminated.
