It is surprising that B16.5 does not have a factor for extreme/accidental cases. I have seen many flange designs where the loading on the flange is taken close to the allowable pressure for normal design conditions. Any additional temporary loading would therefore take it over that limit and...
OK, so rather than using the rated pressure as a limit, you suggest a full ASME flange design calc to ensure the stress and bolt loads are OK.
In terms of acceptable bolt loads and stress, the ASME approach always uses very low allowable stress (33% SMYS) and low bolt loads (<25% SMYS). In...
I have a subsea pipeline system and spool that runs through an area with mild seismic activity. The flanges have all been checked against ASME B16.5 allowable pressure for normal operating conditions and pass easily.
During a seismic event, the displacement of the platform means that the...
Hi
I am trying to track down some compression stress-strain tables for Neoprene rubber (Polychloroprene), IRHD 60. I have a problem which is very sensitive to the amount of compression that the neoprene can withstand in a region with a free edge (it is free to bulge).
Any suggestions?
Thanks
