How does the edge action of the R-Ring Gasket RTJ assembly achieve sealing when compressive force is applied?

The edge action of the RTJ (Ring Joint) assembly with R-type ring gasket when compressive force is applied is a key step in achieving sealing. This sealing mechanism is achieved through precision design and engineering, ensuring reliability and durability in high-pressure environments.
In RTJ assemblies, the gasket is installed between two flanges connecting pipes or equipment. When pressure is applied to the connection, these gaskets are subjected to compression, resulting in slight deformation of the edges around the gasket. This deformation is called edge action and is one of the key factors in sealing.
The occurrence of edge action mainly depends on the characteristics of the gasket material and its contact with the flange groove. Generally, the gasket material has a certain elasticity and can produce a certain degree of deformation when subjected to compression. At the same time, the precise contact between the gasket and the flange groove is also an important condition to ensure that the edge action occurs.
When pressure is applied to the connection, the edges around the gasket will shrink inward to form a tight seal. This deformation creates a tighter contact between the edge of the gasket and the flange groove, effectively preventing the occurrence of media leakage. The occurrence of edge action enables the gasket to maintain stable sealing performance in a high-pressure environment, ensuring the safe operation of the connection.
In addition, the sealing performance of RTJ assemblies is also affected by factors such as the choice of gasket material and the design of the flange groove. Different materials and design schemes may produce different sealing effects, so it is necessary to comprehensively consider the specific engineering requirements and environmental conditions when selecting and applying.
In general, RTJ assemblies with R-type ring gaskets achieve sealing through the edge action of the gasket when the compression force is applied. This sealing mechanism relies on the elasticity of the gasket material and the precise contact with the flange groove to ensure the reliability and safety of the connection under high pressure. Through precise design and engineering, RTJ assemblies can meet the strict requirements of sealing performance in various industrial applications and are one of the indispensable key components in pipeline and equipment connections.
