RTJ flanges

[elylrc]

Guys,

We specified 36-inch R98 RTJ gaskets. These are octagonal per ASME B16.20. Our client managed to purchase KaMOS oval gaskets. B16.20 does not list oval R98, only octagonal. Can we use oval or are we SOL? This is for subsea 600# sweet gas service.

"Standard Style R Ring Type Joints are
manufactured in accordance with both API 6A
and ASME B16.20 size/ratings. Available in
both oval and octagonal configurations, both
types are interchangeable on the modern
octagonal type grooved flanges."

After looking at the information posted above here is a pretty good list of what's available in the form of ring gaskets.
We use numerous R98 oval gaskets in our Therminol vaporizer heating system.
