Product Description

API 6A ASME B16.20 RTJ Oval and Oct Ring Joint Gasket

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. RTJ Oval and Oct Ring Joint Gaskets are specific types of Ring Joint Gaskets that comply with these standards.

RTJ stands for "Ring Type Joint" and refers to the shape of the gasket, which has a metallic ring with a rectangular cross-section. The RTJ Oval and Oct Ring Joint Gaskets are used in flanged connections where they are compressed between two mating flanges to form a metal-to-metal seal.

ASME B16.20 is the standard that provides specifications for Ring Joint Gaskets used in API 6A flanges. It defines the requirements for the shape, dimensions, material, and testing of Ring Joint Gaskets. These standards ensure that the gaskets are compatible with the flanges and that they provide a reliable and consistent seal.

RTJ Oval and Oct Ring Joint Gaskets are designed to withstand high-pressure and high-temperature applications, and are typically made from materials such as soft iron, low carbon steel, or stainless steel. These gaskets provide a metal-to-metal seal that is highly resistant to leakage and can withstand extreme conditions.

In summary, API 6A and ASME B16.20 are industry standards for Ring Joint Gaskets used in high-pressure and high-temperature applications. RTJ Oval and Oct Ring Joint Gaskets are specific types of Ring Joint Gaskets that comply with these standards and are designed to withstand extreme conditions. They are typically made from metallic materials and provide a reliable metal-to-metal seal in flanged connections.

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.
