NORSOK NCF5 Series
Based on NORSOK L005 code,it is suitable for critical sealing
applications with high thermal expansion, cyclic loading such as
Risers, single point mooring systems, manifolds, X-Trees, subsea
pipelines, heat exchangers and a multitude of process piping
systems.
- RCF Advantage
- Space saving
- Weight saving up to 70%~80% than ANSI flanges
- Double Independent Seals make it safer
- Integrated sealing system (both inside and outside)
- Larger range in design temperature and pressure
- RCF Working Principle
- The RCF compact flange design principle is that the flange face
includes two independent seals. The first seal is created by
application of seal seating stress at the flange heel. The main
seal is the IX seal ring. The seal ring force is provided by the
elastic stored energy in the stressed seal ring. Any heel leakage
will give internal pressure acting on the seal ring inside
intensifying the sealing action.
- RCF Size and Pressure Rating
- 1/2”~48” in size and Class 150# to 2500# in pressure rating
- Bigger size and higher pressure rating on request
- RCF Materials
- ASTM A105, A350 LF2, LF6, A694 F52~F65
- AISI 4130, AISI 8630
- A182 F316/316L, F44, F51, F53, F55, F60
- ASTM B564 N06625
- Other materials on request
RCF Gasket- RCF IX seal ring, axial forces are exerted on the taper of the
metal seal ring and translated into a radial sealing force.
Furthermore with increased pre-load, the bevel is closed and face
to face contact is achieved at the outer wedge while most of the
bolt pre-load is transferred as compressive forces between the
flange faces at the heel.
- RCF Design and Verification
- Roc-Master provides calculation service based on ASME section VIII
Division 2 and PD5500. Also we have ANSYS software engineers to do
the analysis and design verification.
