Thanks for your carefully considered reply.
The flange is under NPS 10 (no kidding!). Per UW-11 (a) (4) it is exempt from radiography.
We have figured out that the weld type is a corner joint, so the E=1 (table UW-12 type (7) - corner joint.
We identified the thinnest material (by inspection)...
We understand that the minimum MAWP component part is to be used in UG-101 for the sample being burst. However, our sample is essentially an o-ring/diaphgragm seal which is sandwiched between a welded 316L flange and an aluminium plate. The sandwhich is fastened by UNC bolts which thread into...
Thanks for your reply.
The trouble we have is that even though the lowest MAWP component part is to be used in UG-101(m), we determined that the lowest MAWP component part is the elastomeric component, for which there is no clar specified minimum tensile strength (because it is elastic). The...
Thanks for your reply.
The trouble we are having is that the burst was due to the yield of the elastomeric parts, and not due to the metallic parts. In particular, the 316L part, which is welded, was determined under UG-27 to be strong enough, and the aluminum components were shown to be...
We burst an assembly that is comprised of elastomer elements, 316SS elements, aluminum elements and cast iron elements. Which one is to be the determining component part for the final MAWP derived from UG-101 (m) equations? Each material yields a different MAWP depending upon the casting...
