The nozzle axis is 90 to the level head, and also the attachment weld includes a 3/8-inch fillet weld. The examiner can quickly gauge the fillet weld to ensure compliance. Currently, allow's mount the very same nozzle in a small diameter vessel shell (Fig. 2).

The assessor needs to right away ask the certification owner concerning this situation. Maybe as easy as the certificate holder having just not carried out that action in the procedure yet, or maybe as negative as his/her having actually attempted to conserve money and time by not beveling completions.
