Metallic Gaskets LATTYgraf REFLEX : High temperature Seal, High pressure Seal

Joint Graphite - Metallic Gaskets

The metallic gaskets LATTYgraf REFLEX consists of:

  • an active component made of expanded graphite to provide sealing efficiency,
  • 2 precision-machined stainless steel outer rings used as compression limiters.

The specific pressure on the expanded graphite required to achieve gasket metal-to-metal contact and ensure tightness remains very stable. This stability at ambient and high temperatures is necessary for proper gasket operation when in metal to metal contact.

The various types of LATTYgraf REFLEX gaskets

  • Gasket with double sealing face for special applications such as exchanger-type,
  • Gasket for flanges with single or double recess,
  • Gasket for valve bodies.

Specifications of the LATTYgraf REFLEX metallic gaskets :

  • The sealing efficiency of LATTYgraf REFLEX is not affected by changes in pressure or temperature of the fluid to be sealed, even with rapid and significant changes.
  • The stainless steel ring in contact with the flange faces absorbs the mechanical loads, while the highly elastic expanded graphite crown ensures leak-tight operation.
  • Improved reliability of the bolted assemblies subjected to thermal stresses and preserved sealing efficiency in the event of upset conditions.
  • Reduces the stresses on bolts, thus providing an extra margin to handle additional stresses due to temperature changes.
  • Excellent repeatability guarantees the tightening components thanks to the low dispersion of the loads to be applied to the gasket to achieve leak-tight operation.
  • Possible use, depending on the various parameters, of all machineable materials whose characteristics are compatible with the operating conditions.
  • The compression limiter absorbs all the mechanical stresses due to pipework, thermal shocks, etc. while the active expanded graphite part remains low stresses mechanically.
  • The outstanding elastic recovery of the tightly wound expanded graphite provides LATTYgraf REFLEX with a very high release capability. The recovery represents approx. 10% of the thickness of the compression limiter.
