RING JOINT GASKET

Ring joint gaskets are metallic sealing rings suitable for high pressure and high-temperature applications. They are manufactured in two kinds of cross-section: octagonal and oval accordance. The Ring-Type joint metal gaskets (also called RTJ gaskets or API joint gaskets) are heavy-duty, high-pressure gaskets largely used in the offshore and onshore petrochemical industry, oil-field drilling and completion equipment, and in valves and pipework assemblies, along with some high integrity pressure vessel joints. The right gasket material must be selected based on chemical compatibility with the media and the hardness of the flange.

Generally, the gasket material should be roughly 30 Brinell less than the flange material to ensure sufficient deformation of the gasket without damaging the flange facing. Ring joint gasket is used in connection with RTJ flange, generates a strong seal between two mating flanges. When the flanges are fixed by bolts, the ring joint gasket is squeezed into the groove of the flange, forming a tight seal between the mating flanges. To avoid the destruction of the flanges, the material of the ring joint gaskets must be softer than the material of the flanges. These gaskets are solid metal gaskets used to withstand high temperatures and pressure. It is recommended that gasket material should be softer than the mating flanges. Some types of ring joint gaskets are activated when high pressure is applied, which means the higher the pressure, the better the sealability. The surface of contact between flange and gasket has to be processed carefully to ensure perfect sealing.

Features of ring joint gasket:

High durability and reliability

Available in various specifications

Made of best grades of materials

Highly qualitative

Corrosion-resistant

A ring-type gasket is placed and installed inside of the flange bolts and around the pipe bore. It has no bolt holes and is typically used on raised face flanges since it can easily sit right on top of the flange. Due to its composition, it can be installed without disassembling the joint. SEF is offering Ring Joint Gaskets, which are used in various industries including engineering, automobiles, and heavy industries. We provide various types of flanges, as per customer demands. Our ring joint gaskets are suitable for high-pressure and high-temperature applications. These are used in high temperature and pressure sealing applications in the drilling, completion, chemical and petrochemical industries.
