Product Description

Octagonal Ring Type Joint Gasket for Valve

An Octagonal Ring Type Joint Gasket is a type of metallic gasket that is designed to be used in high-pressure and high-temperature applications. Octagonal Ring Type Joint Gasket is commonly used in the oil and gas industry for flange connections in pipelines, valves, and pressure vessels. The Octagonal Ring Type Joint Gasket is made from a solid metal ring with an octagonal-shaped cross-section that is designed to be used with ring-type joint (RTJ) flanges.

The octagonal shape of the Octagonal Ring Type Joint Gasket ensures that the sealing surfaces of the flange and gasket are held tightly together under high pressure. The Octagonal Ring Type Joint Gasket is designed to be installed in the RTJ flange groove, where it is compressed by the bolts that hold the flange assembly together. This compression causes the Octagonal Ring Type Joint Gasket to deform and fill any imperfections in the flange surfaces, creating a tight and reliable seal.

Octagonal Ring Type Joint Gasket is typically made from high-strength materials such as stainless steel, carbon steel, and alloy steel. The material chosen for the gasket depends on the specific application requirements such as temperature, pressure, and chemical compatibility. The Octagonal Ring Type Joint Gasket can also be coated with materials such as soft iron, copper, or nickel to enhance its sealing performance.

The Octagonal Ring Type Joint Gasket is designed to withstand extreme temperatures and pressures, making it ideal for use in harsh operating conditions. The maximum pressure and temperature that the Octagonal Ring Type Joint Gasket can withstand depend on the material used and the dimensions of the gasket. However, in general, the gasket can handle pressures up to 10,000 PSI and temperatures up to 1000°F.

One of the advantages of the Octagonal Ring Type Joint Gasket is its ability to be reused. Unlike other types of gaskets, such as spiral wound or sheet gaskets, the Ring Joint Gasket can be removed and reused multiple times, as long as it is not damaged or deformed. This makes Octagonal Ring Type Joint Gasket a cost-effective solution for applications that require frequent maintenance or replacement of flange assemblies.

In conclusion, the Octagonal Ring Type Joint Gasket is a highly reliable sealing solution for high-pressure and high-temperature applications. Octagonal Ring Type Joint Gasket is unique octagonal shape and solid metal construction make it an ideal choice for the oil and gas industry, as well as other industries that require strong and reliable sealing solutions. With proper installation and maintenance, the Octagonal Ring Type Joint Gasket can provide a long-lasting and cost-effective sealing solution.

Please consult a Hi-Tech Gasket representative.

 

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.

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.
