The R Type Joint Gasket is initially developed for high pressure/ temperature applications which found in the petroleum industry and is primarily used in the oilfield on drilling and completion equipment. However, today this product range can also be found on valves and pipe work assemblies, along with some high integrity pressure vessel joints.
Style R gaskets are manufactured in accordance with both API 6A and ASME B16.20 to suit API 6B and ASME/ANSI B16.5 flanges.
API ring Joint gaskets come in two basic types, an oval cross section and an octagonal cross section. These basic shapes are used in pressures up to 10,000 psi. The dimensions are standardized and require specially grooved flanges. 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. The sealing surfaces on the ring joint grooves must be smoothly finished to 63 micro inches and to be free of objectionable ridges, tool or chatter marks. They seal by an initial line contact or an edging action as the compressive forces are applied.
