standard.
-
• R(Oval)Ring joint
gasket with oval cross section, suitable for ANSI B 16.5,ASME B16.47, series A
flange, can be used in pressures up to 1000 PSI
-
• R(Octagonal)Ring
joint gasket with octagonal cross section are designed for flanges with standard
grooves,interchangeable with oval ring joint gaskets on modern octagonal grooved
flanges, but has a higher sealing ability.
-
• RX
Ring joint gasket is designed for pressures up to 5,000 PSI. They are
interchangeable with R-oval or R-octagonal rings used on API 6B flanges.
-
• BX Ring joint gasket can only be used
with 6BX flanges and 16BX hubs. BX Gaskets are designed for higher-pressure ratings starting at
5,000 lbs. and ending with 20,000 lbs.
