Product Description

IX Type Ring Joint Gasket

The metal ring joint gasket is made of metal material by forging and heat treatment and machining. Designed for use where NORSOK standard CFC (compact
flange connection) is used. The standard number is NORSOK standard I-005 (ncf5), Type IX sealing ring is an elastic sealing type, which is caused by radial
deformation caused by wedge action of sealing groove. When bearing internal pressure and external pressure capacity is not limited, the pressure is self
tightening.
Typical minimum yield stress and ultimate stress of the seal ring material shall at maximum design temperature be 300MPa and 360MPa, respectively, in order
to allow for reasonably elastic spring-back. Lower strength may be used, but is not recommended. The user is responsible for selecting a seal ring material
which is suitable for the service medium and the design temperature conditions. Seal ring materials are commonly chosen to be compatible with the flange
material, I.e. Duplex seal ring in duplex flange.
