[MW:28006] Re: QW-452.3 / QW 403.16 - GROOVE-WELD DIAMETER LIMITS // set-on or set-in type nozzles

Update : QW-403.16 Subparagraph (a) and (b) added –

(a) For a groove weld attaching a set-on nozzle or branch (with the weld preparation on the nozzle or branch), the range qualified from Table QW-452.3 shall be based on the nozzle or branch pipe O.D.

(b) For a groove weld attaching a set-in nozzle or branch (with the weld preparation on the shell, head, or run pipe), the range qualified from Table QW-452.3 shall be based on the shell, head, or run pipe O.D.

Background – Revised to define welder qualification diameter limits for set-on and set-in nozzle or branch connections.
