Lens Rings

60% Complete

Lens Rings offer high integrity metal to metal sealing with their main usage in high pressure high temperature sealing applications. Goodrich Gasket Pvt. Ltd. manufactures lens rings under DIN 2696 specifications made to suit ASME B16.5 and other modified flanges.

Lens rings have a metallic gasket design featuring spherical sealing faces to fit into flange recesses. All lens rings are made to be softer than flange grooves so that the gasket plastically deforms on compressive load rather than the flanges. Distribution of compressible loads spreads the gasket facings thereby preventing the over stressing of the gaskets.

In accordance with DIN 2696 certain specified grades of Carbon Steel, Stainless Steel are used for lens rings and alternate grades upon request are also incorporated to the lens ring material. Goodrich gasket requires detailed drawings for non standard lens rings.

Given below are dimensions (mm) of the lens rings being offered by Goodrich Gasket Pvt Ltd:-
