[MW:24777] Nozzle Marking On Cap

Dear Design Experts,

With reference to the attached sheet for 1" Nozzle Marking on a 10" Sch 20 SA-234 WPB Seamless Cap for a pressure Vessel construction as per ASME Sec VIII , Div-1, 2015 Ed ,

My query is, can we consider the Seamless CAP ( ASME B16.9 ) as same as 2:1 Ellipsoidal Head for the Nozzle marking calculation, provided in the attachment for opening , inorder to find Arc length.

Also, I need reference to consider Cap as 2:1 Ellip. Head in ASME Code.



Regards ,
Saravanan
