In the case of the oval ring joint gasket, the annular circular surface of the gasket presses against the trapezoidal groove of the flanges.The sealing surface pressure increases under-proportionally to the increase of the bolt force.
Ring Joint Gasket Type R Octagonal
The octagonal ring joint gasket acts as a spherical gasket, thereby creating a larger contact or sealing surface. The effect is larger than in the case of the oval ring joint gaskets.The sealing surface pressure increases proportionally to the increase of the bolt force.
Ring Joint Gasket Type BX
The gasket has a square cross-section with bevelled corners. The diameter of the ring joint gasket Type BX is slightly larger than that of the groove. It as such remains pre-compressed and thereby creates a high sealing value. The compensating bores correspond to the API. The sealing surface pressure increases proportionally to the increase of the bolt force
Ring Joint Gasket Type RX
The gasket has been designed to take advantage of the fluid pressure and to increase the sealing values. The higher the inner pressure, the more the side surfaces press the ring joint gasket Type RX into the groove surface.The sealing surface pressure increases proportionally to the increase of the bolt force.
