ASME B16.20 Oval Octagonal High Temperature and High Pressure Ring Joint Gasket
ASME B16.20 Oval Octagonal High Temperature and High Pressure Ring Joint Gaskets (RTJ) are commonly used in high-pressure and high-temperature applications. This ASME B16.20 Oval Octagonal High Temperature and High Pressure Ring Joint Gasket is designed to provide a reliable seal in harsh environments where resistance to corrosion and high-temperature and high-pressure conditions are essential. In this article, we will discuss the use of ASME B16.20 Oval Octagonal RTJ gaskets.
The ASME B16.20 standard specifies the dimensions, materials, and design of RTJ gaskets. These gaskets are commonly used in flanged joints for piping systems and pressure vessels. The gaskets are designed to fit into the machined grooves of the flanges and provide a tight seal under high-pressure and high-temperature conditions.
The Oval Octagonal RTJ gasket is designed to provide a reliable seal in applications where there is a high degree of temperature and pressure variation. The gasket is made of metal and has an oval or octagonal cross-section. The gasket is designed to fit into the corresponding machined groove on the flange. The gasket is compressed between the flange faces, creating a tight seal.
The Oval Octagonal RTJ gasket is commonly used in oil and gas refineries, chemical processing plants, and power generation facilities. These gaskets are designed to withstand extreme temperature and pressure conditions, making them ideal for use in harsh environments. The gaskets are commonly made of materials such as stainless steel, carbon steel, and other alloys.
Proper installation of the Oval Octagonal RTJ gasket is critical to ensure a reliable seal. The gasket must be installed in the correct groove and compressed evenly to achieve an effective seal. Over-compression can damage the gasket, while under-compression can result in leaks. It is also important to select the appropriate gasket size and material for the application.
In conclusion, ASME B16.20 Oval Octagonal High Temperature and High Pressure Ring Joint Gaskets are commonly used in high-pressure and high-temperature applications. These gaskets are designed to provide a reliable seal in harsh environments where resistance to corrosion and high-temperature and high-pressure conditions are essential. Proper installation and selection of the appropriate gasket size and material are critical to ensure a reliable seal.

*Stainless Steel 316 and 304 can exceed continuous operating temperatures (Up to 760C), however this will result in inter-granular corrosion. 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.
