Deficiencies Summary

Deficiencies for Nozzle #1 (N1)Nozzle MAWP (196 psi) is less than the design pressure (285 psi).UG-39(b): Opening larger than d/2. The flat welded cover and centrally located opening should be modeled using anAppendix 14 Flat Head component.UG-39(b)(3): The width of the ligament between the edge the opening and the edge of the flat head (2 in) is less thanone quarter the opening diameter (3 in).Nozzle MAP (196 psi) is less than the design pressure (285 psi).UG-39(b)(3): The width of the ligament between the edge the opening and the edge of the flat head (2 in) is less thanone quarter the opening diameter (3 in) (MAP Condition).

Warnings Summary

Warnings for Nozzle #1 (N1)The limits of reinforcement of Nozzle #1 (N1) fall off of Welded Cover #1. You may address this issue by relocatingthe nozzle or specifying a user defined radial limit of reinforcement by clicking on the Calculation Options button in theDetailed Nozzle Design dialog. (warning)

Warnings for VesselSupports have not been added to this vessel; combined loads are not being considered. (warning)The vessel does not have a top closure (head or cover). (warning)
