Metal Lens Gasket-EC2

Metal Lens Gasket-EC2

High pressure pipe connection, the widely used lens gasket sealing structure. Lens gasket seal face were spherical, contact with the pipeline cone sealing faces, the initial state for a loop. Under the pre-tightening force, lens pad in contact produce plastic deformation, the loop into a ring, good sealing performance. 
Due to the contact surface is made up of spherical and cant naturally formed, in a gasket is easy. Lens gasket seal belongs to forced sealing, sealing surface for spherical surface and conical surface contact, easy appear indentation, poor interchangeability of parts. In addition, the gasket manufacturing cost is higher, processing also more difficult.

Metal lens gasket performance characteristics

• high temperature resistant, resistant to high pressure, suitable for high pressure flange,
• reliable sealing persistent,
• to adapt to the working conditions of pressure and temperature fluctuations.
