Ring Joint Gasket

Ring joint gasket can be used under the vacuum condition of 1000kgf/cm2 and more for high-pressure vessel, tower and vessel, valve bonnet, etc. including high-temperature and high-pressure steam, oil, gas, solvent, etc.

There are oval type and octagonal type as its representative shape, which can be generally used for pressure of max. 350kgf/cm2 and there is BX type for more pressure. As for oval type and octagonal type, oval type has bigger flange groove deformation.

It is because gasket itself is deformed while bolt is extended until arriving to constant pressure by increased flange connection pressure and line contact is moved to surface contact as well. Therefore, it has good initial sealing performance but gasket is largely deformed.

When Octagonal type is internally pressured, contact pressure with flange is increased, which is initially connected to surface contact. So it requests high connection pressure. But as for sealing characteristics, we can’t clearly say what type is better. Generally, octagonal type is widely used. RX type can be used for flange groove of ring joint gasket but BX type can be only used with API- STD-6BX flange.
