Working principle of compact flange (RCF):

Design principle of compact flange (RCF) is the separate dual seal system of the flange sealing surface. The bottom of wedge-shaped flange face forms the first seal for the pressure brought about by the bolt preloading force; the primary seal is from IX sealing ring and the sealing force is mainly from the elastic energy of the sealing ring itself under the strained condition. If there is seal leakage at the bottom of the wedge-shaped flange edge, then the internal pressure expands to the outer diameter direction that will also enhance the sealing.

Advantages of compact flange (RCF):

• Save space;
• Compared to ANSI flange, its weight saves about 70%~80%;
• Separate dual seal, and be more secure;
• Positive sealing ways;
• The integrated sealing system (internal and external);
• A wider temperature and pressure range in design.

Compact Flange (RCF):

Size and pressure rating of compact flange (RCF): 

• Size of 1/2" to 48" and the pressure rating of 150# to 2500#
• For larger size and higher pressure rating, please consult the factory.

Materials of compact flange (RCF):

• ASTM A105, A350 LF2, LF6, A694 F52~F65
• AISI 4130, AISI 8630
• A182 F316/316L, F44, F51, F53, F55, F60
• ASTM B564 N06625
• For other materials, please consult the factory.

Gasket of compact flange (RCF):

For RCF IX gasket, the axial force applied to the conical surface of the metal seal ring is converted to the radial sealing force. As the bolt's preloading force loads until the entire flange outer edge is sticked tightly, wedge-shaped flange's sealing surface and sealing ring's conical surface and the groove conical surface are closely fitted, and most bolt preloading force is converted into the pressure at the bottom of the wedge-shaped flange's sealing surface.

Design and verification of compact flanged gasket (RCF):

We may provide the design and computing services, calculated by the methods on the basis of Chapter 1, 2, 3 of Vol.8 of ASME. We also provide the analysis and design validation service of ANSYS certified engineers.
