In Casear II Ver 4.3, we do not have facility to compute SIF for brach type "Sockolet". Weldolet has "BW" connection at branch end whereas Sockolet has "SW" connection. However, the Olet which is sitting on the header pipe has same configuration. Hence shall I consider "Sockolet" as same as "Weldolet" as far as branch type is defined, as we intend to calculate SIF for the branch. Could anybody support this logic?
