eadwine - would you be able to direct towards a supplier where they clearly specify that it is rated per the flange class?
All of my google searches have rendered me suppliers of bleed rings but unfortunately never any reference to a design standard. Thanks
I am not considering a program for analysis etc. Just trying to justify the ring in accordance with B31.3.
I am considering a ring flat faced on both sides fit in between a set of RF flanges. It is pretty intuitive that it satisfies the code requires, but intuitive just is not going to cut...
Thanks for the info. I was thinking, I wonder if you can just 'model' the ring as a piece of thick pipe with a socket-weld connection as a fabricated assembly which would comprize of pipe and a listed fitting.
Client request to use a bleed ring between flanges. Since bleed rings are not listed as a standard component, what would be the best approach per 304.7.2?
I know they are used quite often per part(a) but do not have anything really to substantiate the use.
Bleed rings required on CL 150...
