Oval Octagonal Bx/Rx/IX Ring Joint Gasket for Pipe

Oval Octagonal Bx/Rx/IX Ring Joint Gasket for Pipe

Ring joint gaskets are used to seal the joints between pipe flanges, valves, and other equipment. They are commonly used in high-pressure and high-temperature applications where a reliable and leak-free seal is essential. The BX, RX, and IX ring joint gaskets are three types of ring joint gaskets commonly used in the oil and gas industry.

The BX ring joint gasket is a pressure-energized gasket designed for high-pressure applications. It has a trapezoidal cross-section and is suitable for use with BX flanges. The BX gasket is made of a soft iron or low carbon steel core, which is then covered with a soft metal like copper or silver. This construction allows the gasket to deform and seal under high pressure, providing a reliable and leak-free seal.

The RX ring joint gasket is also a pressure-energized gasket, but it has a circular cross-section. The RX gasket is suitable for use with RX flanges and is commonly used in high-pressure and high-temperature applications. The RX gasket is made of a soft iron or low carbon steel core, which is then covered with a soft metal like copper or silver. The circular cross-section of the RX gasket allows for greater contact with the flange face, providing a more reliable and leak-free seal.

The IX ring joint gasket is a pressure-energized gasket designed for use with IX flanges. The IX gasket has an oval or octagonal cross-section and is commonly used in high-pressure and high-temperature applications. The IX gasket is made of a soft iron or low carbon steel core, which is then covered with a soft metal like copper or silver. The oval or octagonal shape of the IX gasket allows for greater contact with the flange face, providing a more reliable and leak-free seal.

In conclusion, the BX, RX, and IX ring joint gaskets are essential components in high-pressure and high-temperature applications in the oil and gas industry. Choosing the right type of ring joint gasket for a specific application is crucial to ensure proper sealing and efficient operation. When selecting a ring joint gasket, it is essential to consider factors such as pressure, temperature, flange type, and material compatibility to ensure optimal performance.

R & RX Series

R series

R Series ring type joint gaskets are available in oval and octagonal designs. The oval design can be used in older round bottom gland designs, while both can be used in a flat bottom design. R Series are available up to 5,000 PSI.

RX Series

RX series are replaceable with R series octagonal gaskets designed for API 6B flanges. RX out perform R series in situations that have higher pressures with more intense vibrations. RX gaskets are available up to 5,000 PSI.

Flange ring joint gasket, Style BX


Ring Joint Gasket, Style IX

IX Seal Rings are designed and used where NORSOK CFC (Compact Flange Connections) are in use. The rings come in three different kinds of steel and are coated with PTFE in varying colors in order to distinguish between them

The designed or materials shall be selected, so that main sealing ares can not be subject to corrosion.
How IX Ring Seal Works?

IX Seal Ring axial forces are exerted on the taper of the metal seal ring and translated into a radial sealing force.

Furthermore with increased pre-load, the bevel is closed and face to face contact is achieved at the outer wedge while most of the bolt pre-load is transferred as compressive forces between the flange faces at the heel.

There are two independent seals. The first seal is created by application of seal seating stress at the flange heel. The flange also remains in contact along it`s outer circumference at the flange faces for all allowable load levels. The main seal is the IX Seal Ring. The seal ring force is provided by the elastic stored energy in the stressed seal ring. Any hell leakage will give intemal pressure acting on the seal ring inside intensifying the sealing action.

The design aims at preventing exposure to oxygen and other corrosive agents. Thus, this prevents corrosion of the flange faces, the stressed length of the bolts and the seal ring.


Application of ring joint gaskets

Usually used in high temperature and high pressure steam, gas, solvent tube flange, tank, pressure vessel, the joint surface, high temperature and high pressure valve, the cover.Oil and gas industry in wellhead sealing and oil extraction tree.
