CF7000 type R octagonal

CF7000 is an octagonal ring joint type that is particularly suitable for installation on newly manufactured flanges, such as high-pressure valves.
They come in various materials: Fe Armco/Soft Iron; Stainless steels 304, 316, 321, 347; Alloys 400, 600, 625, 800, 825; Hastelloy C276, B2.v
It can be produced in other materials on request.
They are very common in refineries and in newly installed high-pressure pipelines.
These gaskets are not recommended for installation on existing flanges with worn gasket seating.
The reference standards for these ring joint gaskets are ANSI B16.5 and B16.47 A.

  • Ideal in the presence of very high pressures
  • High compressive strength
  • Wide choice of structural conformations and types of alloys
  • Ideal for the Oil & Gas sector
