Design using Asme Code in combination with other codes. 1

[abangbikerz]

Currently im designing a quick actuating door where it is design to ASME VIII div 1 and the area where flange and lock ring is design according to JIS standard as this type of flange connection with lockring is not mentioned in ASME VIII. Is it allowed by ASME code?? And this is not code stamped vessel.

abangbikerz, do I understand, part of the quick opening closure is designed per ASME and part is JIS?

For the entire closure to comply with Sec VIII, Div 1 those rules must be followed, where they exist. If you were to stamp as a Part w/ U-2 it would have to comply.

However if you just need a thing to put on a non ASME vessel, ASME does not care.

Is your vessel being certified to any recognized Code? If so, that Code most likely does care.

The vessel is design according to ASME VIII using a software where the things like thickness, nozzle analysis etc is calculated to ASME. It is a door where the door is keep secured using a flange and lockring. Just like the door that is used in most autoclave. Those are the area where asme doesnt specifically mention the rules on how to design it. However appendix ff does mention that code cant address everything about designing a door, so good engineering judgement must be used etc. So does it mean i can used other standards design criteria just on that flange and lockring part?
This is not going to be code stamp. But i still need to prove it to my client that it will comply to relevant code and standard.

Still don't have a good understanding of what you are doing. How does JIS standard fit in? If you talk of a "flange" there are Code rules for design of such. Certain other parts of the closure, correct, no exact rules exist, rules from other Codes or standards may possibly be applied.

Please carefully read and absorb the entirety of FF-3. Quick acting closures are potentially very dangerous. If you are not experienced in the design of same I'd say you need to hire it out.

Otherwise, communicate with your client and perhaps your AI exactly your proposed design methodology.

abangbikerz,

ASME UG-35.2 (or UG-35.3) does not give the designer the rules of how the Quick-Actuating (or Opening) Closures shall be look like or how to design it.

But, these paragraphs does contain the mandatory requirements regarding the things that shall be considered when designing a pressure vessel with this kind of Closure.

If you want to use Standard other than ASME VIII-1 to design the Quick-Actuating Closure you may do it provided that it will meet UG-35.2 (or UG-35.3)

For example, in EN 13445-5 Annex C you can find some kind of closures which allowed for use in pressure vessels which designed and constructed in accordance with EN 13445-5 but are not compley with ASME UG-35.2 requirments.
