> Lens ring joint used in higher pressure then 3,000 lbs.
> These gaskets had been used on pipe flanges in synthesizing line.

A lens type 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. These gaskets will seat with a small bolt load since the contact area is very small and gasket seating pressures are very high. Normally the gasket materials should be softer than the flange. In ordering lens gaskets, complete drawings and material specifications must be supplied.

Description

SUNWELL Lens ring joint gasket manufactured in accordance with DIN 2696, provide the engineer with a high integrity, high pressure and temperature seal for special applications.
Lens rings have a spherical surface and are suitable for use with conical flange faces. So other styles are available on request.

Prime Features
As the standard, the gasket material should be softer than the flange material, thus ensuring that the applied compressive load leads to the elastic and plastic deformation of the lens ring and not the flange sealing face

As with all metallic joints, the re-use of lens rings is not recommended.
