Monel flanges follow standard engineering requirements defined by ASTM B564 / ASME SB564 specifications. They are built using nickel-copper alloys like Monel 400 (UNS N04400) or Monel K500 in sizes from 1/2' to 48', spanning pressure ratings from Class 150# to 2500#. Material Grades and Standards • ASTM Spec: ASTM B564, ASTM B865, ASTM B366 • Monel 400: UNS N04400, Werkstoff Nr. 2.4360 • Monel K500: UNS N05500, Werkstoff Nr. 2.4375 Dimensions and Pressure Classes • Size Range: 1/2' (15 NB) to 48' (1200 NB) • Pressure Ratings: Class 150, 300, 600, 900, 1500, 2500; PN6 to PN64 • Dimension Standards: ANSI/ASME B16.5, ASME B16.47 (Series A & B), BS4504, EN-1092, DIN Flange Types and Face Designs • Flange Types: Slip-On (SO), Weld Neck (WN), Blind, Socket Weld, Threaded, Lap-Joint, Orifice • Face Types: Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ) If you need specific details, please let me know:What flange type and pressure class do you require?What is the target pipe size (NBS)?
