Ring Joint Gaskets

Ring joint gaskets are metallic sealing rings suitable for high pressure and high temperature applications and are fitted in ring groove type flanges.

They are widely used in the Oil / Petrochemical industry and in valves and pipe work. Choice of material may be determined to suit higher temperatures and aggressive media. They comply with ASME B16.20 standards and API spec 6A. (where applicable).

Ring Material:

Soft Iron, Steel (LCS), ASTM A 182-F5, SS 304, SS 309, SS 316, SS 316L, SS 321, SS 347, Monel 400*, Inconel 600, Inconel 625, Incoloy 800, Incoloy 825, Titanium.

THE GASKETS ARE AVAILABLE IN 3 TYPES

STYLE R (Oval or Octagonal Shape)

R type ring joint gaskets are available in oval or octagonal cross section and manufactured in accordance to API 6A and ASME B16.20 to suit API 6B and ASME / ANSI B16.5 flanges.

The oval ring fits the round AND flat bottom ring groove flange while the octagonal shape fits only the modern flat bottom groove flange.

STYLE RX

The RX type RTJ gasket is manufactured in accordance to API 6A and ASME B16.20 to suit API 6B and ASME / ANSI B16.5 flanges. The RX is a pressure energized version of the R octagonal gasket and fits the R type flat bottomed groove.

The RX has an increased height and utilizes the internal system pressure to energize and improve the seal as internal pressure increase. Some RX sizes have a pressure relief hole to equalize pressure both sides of the sealing faces.

STYLE BX

The BX type RTJ gaskets are manufactured in accordance with API 6A and are suitable for use in high pressure API 6BX flanges. The gaskets form a metal to metal seal on assembly and the efficiency improves as internal pressure increases. All BX sizes have a pressure relief hole to equalize pressure across sealing faces
