Gasket Spiral Wound or Ring Joint for rating 900# above
(OP)
On pressure rating class 900#, 1500# and 2500#. When do we use Ring Joint and When do we use Spiralwound?
Since most of the oil and gas company prefer Ring Joint gasket for 900# and above.
But some also allows spiral wound on 900#. The vendors also proposed SPWD since it would be more cheaper.

There are other types of non-welded connections, too, that are well-suited for high pressure applications.

As to the issue of which RTJ type, from Lamons:
"The octagonal cross section has a higher sealing efficiency than the oval and would be the preferred gasket. However, only the oval cross section can be used in the old type round bottom groove. The newer flat bottom groove design will accept either the oval or the octagonal cross section."
