• The maximum stress in the flange used at the joint of a pipe line is a meridional one at the outer surface of the hub end, but it cannot be calculated by the formulas in the Standards. In this paper, the stresses of several flanges are determined by the finite element method, and a formula is introduced, by which the maximum meridional stress can be easily estimated by applying the correction factor α^^- to the axial stress σ_z according to the ASME Standard. Then α^^- is given as follows: α^^-=-0.0284×[(S_1-S)/r]^2+0.3815×(S_1-S)/r+0.644 where, S_1: thickness of hub at large end S: thickness of pipe r: fillet radius at hub end
