CF4000 with inner and outer rings

Description:
CF4000 with inner and outer ring is mainly installed on flanged RF type couplings (IBC type).
The presence of the external centering ring and the internal containment ring mean that this gasket can be used on high pressure piping lines.
They can be supplied according to ASME B16.20 or EN 1514-2 standards or customized according to customer specifications.

  • Ideal for the oil & gas industry
  • Excellent mechanical behavior even at high temperatures and pressures
  • Wide choice of structural conformations, types of alloys and fillers
