Product Description

API 6A ASME B16.20 Metal Sealing Ring Joint Gasket for Steam Line

API 6A and ASME B16.20 are industry standards for Ring Joint Gaskets used in high-pressure and high-temperature applications, particularly in the oil and gas industry. A Metal Sealing Ring Joint Gasket is a type of Ring Joint Gasket that conforms to these standards and is designed to provide a tight, leak-free seal in flanged connections.

Metal Sealing Ring Joint Gasket is typically made of materials such as soft iron, low carbon steel, or stainless steel, which are capable of withstanding high pressures and temperatures. The Metal Sealing Ring Joint Gasket is designed to deform under high pressure, filling any gaps or imperfections in the flange surface to create a tight, leak-free seal.

The design of the 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 Metal Sealing Ring Joint 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.

API 6A and ASME B16.20 define the dimensions, tolerances, and materials that must be used for Metal Sealing Ring Joint Gaskets, ensuring that the gaskets are compatible with the flanges and provide a reliable seal. The standards also require rigorous testing to ensure that the gaskets can withstand the pressures and temperatures of the intended application.

In summary, a Metal Sealing Ring Joint Gasket is a type of Ring Joint Gasket that conforms to API 6A and ASME B16.20 standards and is designed to provide a tight, leak-free seal in high-pressure and high-temperature applications. The Metal Sealing Ring Joint Gasket is made of metallic materials 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 Metal Sealing Ring Joint Gasket must conform to rigorous testing and dimensional standards to ensure reliability and compatibility with the flanges.

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.

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.
