CF 9000

Description:

CF9000 series confined gaskets are composed of a metal disk suitably worked on machine tools to create on both faces two grooves (or slots) into which two are inserted seals based on expanded graphite.
These seals are particularly used on equipment with pressures and temperatures of critical work.
The particular shape of the confined gaskets, unites the stability over time of the solid part to the capacity of compensation, adaptation and elastic recovery of graphite also on plant flanges existing. In extreme cases, in place of traditional expanded graphite, two seals can be inserted in Sigraflex Hochdruck Pro with inner and outer reinforcement edge.
This is applied incases of very high pressures, eliminating the blow-out effect of graphite expanded unarmed. In addition to this, the high compressive strength of the Sigraflex Hochdruck Pro allows the application of high loads. CF9000 is particularly used on pressure equipment such as heat exchangers and vessels, with tongue & groove flanges and on design according to customer specifications.
They can replace traditional metalloplastic and camprofile gaskets when there are sealing problems resulting from damaged or non-parallel flanges.

• Suitable for installations at high temperatures and pressures
• Excellent mechanical characteristics
• Wide choice of structural conformations, types of alloys and fillers
