Compact Flange

We are leading manufacturer and stockist of Compact Flange in China.Based on NORSOK L005 code,Website:,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.Compact Flange AdvantageSpace savingWeight saving up to 70%~80% than ANSI flangesDouble Independent Seals make it saferPositive sealing methodIntegrated sealing system (both inside and outside)Larger range in design temperature and pressureCompact Flange Working PrincipleThe Compact Flange 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.Compact Flange Size and Pressure Rating1/2"~48" in size and Class 150# to 2500# in pressure ratingBigger size and higher pressure rating on requestCompact Flange MaterialsASTM A105, A350 LF2, LF6, A694 F52~F65AISI 4130, AISI 8630A182 F316/316L, F44, F51, F53, F55, F60ASTM B564 N06625Other materials on requestCompact Flange GasketCompact Flange 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.Compact Flange Design and VerificationPESCO 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.ONE OF THE KIND, MILLIONS OF CHOICESSUPERIOR QUALITYPROMPT DELIVERYFAVORABLE FEEDBACKALL AVAILABLE IN PESCOSELECT PESCO, YOU WILL BE RIGHTFor more info and price of Compact Flange, please send us inquiry and you will have quick reply soon.
