Duplex Steel Flange Wall Thickness Schedule Chart Calculation

Duplex Steel 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,

• d = diameter, or short span, measured as indicated in Fig. UG-34.
• 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)
• hG = gasket moment arm, equal to the radial distance from the center line of the bolts to the line of the gasket reaction
• E = joint efficiency, from Table UW-12, of any Category A weld as defined in UW-3(a)(1).
• P = internal design pressure
• S = maximum allowable stress value in tension from applicable table of stress values referenced by UG-23.
• W = total bolt load given for circular heads for Formulas (3) and (4), 2-5(e).
