What are the characteristics of the lens cross-section of the lens ring?

The lens cross-section design of the lens ring is an indispensable part of high-pressure piping systems and pressure vessel heads. This design offers significant advantages in sealing performance, contact area, gasket seat pressure, and more, providing reliable safety assurance for high-pressure piping systems and pressure vessel heads.
Spherical Gasket Surface:The lens cross-section of the lens ring features a spherical gasket surface. This design allows for a tighter fit between the gasket and the flange, improving sealing performance. The spherical gasket surface better conforms to the curved surface of the flange, reducing the risk of leakage.
Small Contact Area:The lens cross-section design of the lens ring results in a very small contact area, which leads to a very high gasket seat pressure. This high pressure ensures a tight fit between the gasket and the flange, preventing medium leakage. Additionally, due to the small contact area, the gasket can generate a greater clamping force under the same bolt load, enhancing the sealing effect.
High Gasket Seat Pressure:Due to the small contact area, the lens cross-section design of the lens ring results in very high gasket seat pressure. In high-pressure piping systems, the medium pressure is often substantial, and insufficient gasket seat pressure can easily to leakage accidents. The lens cross-section design of the lens ring ensures sealing performance by increasing the gasket seat pressure.
Gasket Material Selection:To fully leverage the advantages of the lens cross-section design of the lens ring, the choice of gasket material is crucial. Typically, the gasket material should be softer than the flange so that it can undergo a certain degree of deformation under pressure, better fitting the flange surface. This material selection helps reduce the risk of leakage and improve sealing performance.
High Processing Precision Requirements:The lens cross-section design of the lens ring has a significant impact on sealing performance, thus requiring very high processing precision. Advanced processing equipment and techniques are necessary during manufacturing to ensure the dimensional precision and surface quality of the lens cross-section. Additionally, strict inspection and testing of the gaskets are required to ensure they meet design and usage requirements.
The characteristics of the lens cross-section of the lens ring are mainly reflected in the spherical gasket surface, small contact area, high gasket seat pressure, gasket material selection, and high processing precision requirements. These characteristics collectively provide reliable sealing performance and safety assurance for high-pressure piping systems and pressure vessel heads. In practical applications, it is essential to select the appropriate lens ring model and specifications based on specific usage environments and requirements to ensure it can fully utilize its advantages and meet usage demands. Additionally, proper maintenance and care of the lens ring are necessary to extend its service life and enhance its effectiveness.
