The Ring Type Joint was intially developed for high
pressure/temperature applications found in the petroleum indutry, the
main use bieng in the oil field on drilling and completion equipment.
However, today this product range can also be found on valves and
pipework assemblies, along with some high integrity pressure vessel
joints. Standard Ring Type joints can be categorized into 3 groups:
Ring Type joint Style R
The Flexitallic® Ring Type Joint Style R is available in both oval and
octagonal configurations, both types being interchangeable on the modern
flat bottomed type groove flanges. Standard Style R Ring Type Joints are
manufactured in accordancewith both API 6A and ANSI B16.20
size/ratings.
Ring Type joint Style RX
The Flexitallic® Ring Type Joint Style RX is a pressure energized
adaptation of the standard Style R Ring Type Joint. As the RX is
designed to fit the same groove design as a Standard Style R, the joints
are interchangeable. The modified design uses a pressure energized
effect which improves the efficiency of the seal as the internal pressure
of the system increases.
Ring Type joint Style BX
The Style BX pressure energized Ring Type Joints, maufactured in
accordance with API 6A, are designed for use on pressurized systems upto
20,000 psi. The style BX gasket, when correctly fitted , allows virtual
face to face contact on the flange faces which means that the gasket is
fully trapped on both the inner and outer diameters. All BX gaskets
incorporate a pressure balance hole to ensure equalization of pressure
which may be trapped in the grooves.
