Collar ring in a Exteneded Bonnet valve
Collar ring in a Exteneded Bonnet valve
(OP)
For Cryogenic valves clinet has a requirement for the "Collar rings" at the extended bonnets.
I do not know how/where this collar ring is connected with the extended bonnet. Can some one help on this?

RE: Collar ring in a Exteneded Bonnet valve
Normally they are welded on but with the extended bonnet being a pressure containing component the weld will be classified as a pressure containing weld, with all the certification that that includes.
Good luck.
