Product details

Lens ring joint gasket is manufactured in accordance with DIN 2696, providing 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, they are widely applied in petroleum processing,oil refining ,electricity generated by firepower, valve etc.  As the standard, the lens ring joint 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. but with all metallic joints, the re-use of lens rings is not recommended.
A strict QA system has been set up in accordance  with API 6A for the whole process of our production.Since API 6A Quality management  has been implemented,our level of inspection means and technology has played a  leading role in the sector of sealing elements and we have become a member of  the science  and technology information  network  of the packing static sealing sector of the  state mechanical industry .
