Many clients have drawn on SUNWELL`s specialized knowledge and experience on the use of high pressure and high temperature metal-to-metal static sealing. SUNWELL have developed a sealing system which uses a modified cone ring giving excellent leak tightness properties under the most severe conditions of pressure, temperature, thermal cycling and shock.
IX Seal Rings are designed and used where NORSOK CFC (Compact Flange Connections) are in use. The rings come in three different kinds of steel and are coated with PTFE in varying colors in order to distinguish between them
The designed or materials shall be selected, so that main sealing ares can not be subject to corrosion.
Typical Seal Ring Materials
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.
