Bleed Rings in ASME B31.3 Piping System
Bleed Rings in ASME B31.3 Piping System
(OP)
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, 300, 600 and 900 natural gas service.
Any thoughts?
Thanks

Are you talking about RF or RTJ flanges?
I don't know how our piping system design handles the rings as they came with the original construction. All our rings are installed in RTJ Class 300 flanges.
RE: Bleed Rings in ASME B31.3 Piping System
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 it for satisifying a non-standard component. I do not have access to ANSYS these days nor would it justify such an evaluation. I was hoping that I was missing something elementary.

Hope this helps.

All of my google searches have rendered me suppliers of bleed rings but unfortunately never any reference to a design standard. Thanks

This would give you something tangible to substantiate the design and acceptability of the bleed ring.
