Hi Guys,

Need some help here. Currently, i am designing a High Pressure RTJ Girth Flange. Just want to know is there any pressure rating for O-Rings in accordance to their dimensions? Ur advise is highly appreciated. Thanks.
 
)-rings? rubber O-rings? Or do you mean the metal ring thats inserted in the RTJ flange?
 
Thanks for ur reply. its a metal rings that inserts in the RTJ flange. Have u ever come across with o-rings with partition?
 
ngyc87,

What's high pressure for you? If design is less than ANSI 1500 class, you might take a serious look at SWG's. There are several variations of the metal o-ring design, the one I most familiar with is nominally called 'helicoflex'. I haven't seen any with pass-partitions, but it shouldn't be too hard. Normally, when I see pass-partitions, they are HE related, and in most cases the right SWG, with internal and external metal rings tend to be the best selection.
