Ring Joint Gasket / Lens Gasket

Made from high-performance, durable metal materials, Ginseal lens gasket, also named high-pressure gasket, widely used in all types of high-pressure piping systems and in pressure vessel heads. In the high-pressure pipeline connections, the lens pad sealing structure has a wide. The sealing surface of the lens pad is a spherical surface, which is in contact with the conical sealing surface of the pipe. The initial state is a circular line. Under the action of the pre-tightening force, the lens pad is plastically deformed at the contact point, the ring line becomes an endless belt, and the sealing performance is better. Because the contact surface is naturally formed by the spherical surface and the inclined surface, the gasket is easy to center.

Features:

High temperature and high-pressure resistance, suitable for high-pressure flange;
Durable and reliable seal;
Adapt to the working conditions of pressure and temperature fluctuation

描述

GINSEAL lens gasket is a line contact seal for use in high-pressure piping systems and in pressure vessel heads. The lens cross-section is a spherical gasket surface and requires special machining on the flanges. Since the contact area is very small and gasket seating pressures are very high, the gaskets will seat with a small bolt load. Normally the gasket materials should be softer than the flange. In ordering lens gaskets, complete drawings and material specifications must be supplied.
Most popular metal lens gaskets are manufactured according to the standard of DIN 2696, from this standard, we can provide lens gaskets with dimensions from DN10 PN63 up to DN300 PN400.

Besides DIN 2696, there are also other standards that describe particular shapes and dimensions in detail.
Ginseal also provides non-standards lens metal gasket based on the provided drawings.
Unlike Ring type joint gaskets, Lens gaskets are reusable, as the sealing effect is generally achieved by elastic deformation of the surfaces.

Details About Lens Gaskets

Item No.: JSG-RJL
Lens gaskets are normally used as high-pressure gaskets.
Lens gaskets are stress-resistant.
The seating area of the lens assembled in the turned flange groove
Increases by increasing bolt load.
One disadvantage, however, is that under high pressure and
Temperatures, the circumference of the gasket lens may bulge which
This leads to loss of initial load.
Other designs are available on request.
