> Ring Joint Gaskets are for oilfield and process industry duties. > Octagonal shape gasket is belong to API 6A R series > These gaskets are used in pressures up to 10,000 PSI, more than Oval ring joint. > The oval type is the only gasket that will fit a bottom radiused groove. > Gaskets and not re-used after torque.
> Ring Joint Gaskets are for oilfield and process industry duties. > RX gaskets are designed for pressures up to 15,000 PSI. > RX types of gaskets are more costly then Oval and Octagonal rings. > RX type gaskets perform excellent in API 6B flanged.
> Although similar in style to the octagonal ring joint > BX series can only be used with 6BX flanges > BX rings for higher pressure rating starting at 5,000 lbs, and ending with 20,000 lbs. > Rings can not be re-used.
> Lens ring joint used in higher pressure than 3,000 lbs. > These gaskets had been used on pipe flanges in synthesizing line.
API ring Joint gaskets come in two basic types, an oval cross section (Style 377) and an octagonal cross section (Style 388). These basic shapes are used in pressures up to 10,000 psi. The dimensions are standardized and require specially grooved flanges.
