Heavy working conditions requires gaskets able to ensure a perfect seal.
A leakage at high pressure and temperature could be dangerous for operators and for the environment.
Lens Gaskets has been developed for work in severe condition.
They are characterized by a spherical sealing surface which is in contact with the conical surface of the flange.
They are used for very special applications, in terms of pressure, temperature and their changes over time.
Usually they are installed on the flanged connections of reactors at high pressure.
