High Pressure Metal Sealing Ring Joint Gasket for B16.5 Flange

High Pressure Metal Sealing Ring Joint Gasket for B16.5 Flange

A High Pressure Metal Sealing Ring Joint Gasket is a type of metallic gasket designed for use in high-pressure applications where conventional gaskets may fail. B16.5 is a standard specification for flanges, valves, and fittings in sizes NPS 1/2 through NPS 24.

A High Pressure Metal Sealing Ring Joint Gasket designed for use with B16.5 flanges is typically made of metal such as soft iron, low carbon steel, or stainless steel, and is designed to deform under high pressure and fill any gaps or imperfections in the flange surface, creating a tight, leak-free seal.
 

The design of the High Pressure Metal Sealing Ring Joint Gasket includes a metallic ring with a trapezoidal cross-section, which is positioned inside a groove in the flange face. When the flanges are bolted together, the gasket is compressed, forcing the ring to deform and seal the gap between the flanges. The pressure exerted on the gasket by the flanges creates a metal-to-metal seal, which is highly resistant to leakage.

In addition to its ability to withstand high pressures, a High Pressure Metal Sealing Ring Joint Gasket designed for use with B16.5 flanges must also conform to the dimensional and tolerance requirements specified by the B16.5 standard. These requirements ensure that the gasket is compatible with the flanges and that it provides a reliable and consistent seal.

In summary, a High Pressure Metal Sealing Ring Joint Gasket for B16.5 flanges is a type of metallic gasket designed to provide a tight, leak-free seal in high-pressure applications. The gasket is typically made of metal such as soft iron, low carbon steel, or stainless steel and includes a metallic ring with a trapezoidal cross-section, which is compressed between two flanges to create a metal-to-metal seal. The gasket must conform to the dimensional and tolerance requirements specified by the B16.5 standard to ensure compatibility with the flanges and reliable sealing 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.

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.
