Super Duplex Flanges

All Super Duplex Steel Flanges contains a higher chromium and molybdenum content which make it suitable to use in oil and gas extraction from sour wells, aerospace, petrochemical, motorsport & refineries industry. These Super Duplex Stainless Spectacle Blind Flanges (BLRF) are known for duplex microstructure which provide high strength and high resistance to stress corrosion cracking. The specification included to these flanges is ASTM A182, ASME SA182 F51, F57, F60, and F61. Available sizes of this Super Duplex Flange Material varies from 1/8 NB to 48 NB and scheduled to different classes and sections like 5S, 10S, 20S, 50S, 80S, 100, XS, and XXS and classes 150LBS, 600LBS, 1500LBS, and 2500LBS. Super Duplex Stainless Steel Flanges can be used for their good mechanical properties in the welded condition because compare to austenitic stainless steels it has twice high minimum yield stress values.

Super Duplex Flange Thickness Calculation

Super Duplex Flange thickness calculation as per ASME B31.3 Section 304.5.2

• To calculate t, the rules of Section VIII, Division 1, UG-34 may be used
• The minimum thickness, considering the manufacturer ’s minus tolerance, shall be not less than tm
• The minimum required thickness of flat unstayed circular heads, covers and blind flanges attached by bolts causing an edge moment in which case the thickness shall be calculated by the following formula:

Where,

• C = a factor depending upon the method of attachment of head, shell dimensions, and other items as listed in (d) below, dimensionless. The factors for welded covers also include a factor of 0.667which effectively increases the allowable stress for such constructions to 1.5S. (in our case C= 0.3)
• E = joint efficiency, from Table UW-12, of any Category A weld as defined in UW-3(a)(1).
• d = diameter, or short span, measured as indicated in Fig. UG-34.
• W = total bolt load given for circular heads for Formulas (3) and (4), 2-5(e).
• P = internal design pressure
• hG = gasket moment arm, equal to the radial distance from the center line of the bolts to the line of the gasket reaction
• S = maximum allowable stress value in tension from applicable table of stress values referenced by UG-23.
