Product Description
Soft Iron/SS304/SS316L/347/Inconel/Monel Ring Joint Gasket for RTJ Flange
Soft Iron/SS304/SS316L/5 Ring Joint/347 Ring Joint Gasket is commonly used in high-pressure and high-temperature applications in the oil and gas industry, chemical processing plants, and other industries where reliable seals are required to prevent leaks. Each of these materials has unique properties that make them suitable for specific applications.
Soft iron is a low-cost material that is commonly used in low-pressure applications. It is known for its malleability and ability to conform to irregular flange surfaces. Soft Iron,SS304,SS316L,5 Ring Joint,347 Ring Joint Gasket is typically used in low-pressure, non-critical applications.
SS304 and SS316L are both types of stainless steel that are commonly used in high-pressure and high-temperature applications. SS304 is a general-purpose stainless steel that is often used in applications that require good corrosion resistance. SS316L is a higher-grade stainless steel that is known for its excellent resistance to corrosion and oxidation. Both SS304 and SS316L ring joint gaskets are suitable for use in a wide range of applications, including those that involve corrosive media.
The 5 ring joint gasket is a specialized gasket that is designed for use in high-pressure applications. It is commonly used in the oil and gas industry for wellhead flanges, Christmas tree valves, and other high-pressure applications. The 5 ring joint gasket is made of a soft iron or low-carbon steel ring that is covered with a thin layer of soft facing material, such as graphite or PTFE.
The 347 ring joint gasket is a specialized gasket that is designed for use in high-temperature applications. It is made of a soft iron or low-carbon steel ring that is covered with a thin layer of soft facing material, such as graphite or PTFE. The 347 ring joint gasket is designed to withstand temperatures up to 800°F (427°C) and is commonly used in applications that involve high-temperature steam, heat exchangers, and boilers.
Proper installation of ring joint gaskets 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.
In conclusion, soft iron, SS304, SS316L, 5 ring joint, and 347 ring joint gaskets are commonly used in high-pressure and high-temperature applications. Each of these materials has unique properties that make them suitable for specific applications. Proper installation and selection of the appropriate gasket size and material are critical to ensure a reliable seal.

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.
Flange ring joint gasket, Style BX
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.
