The vertical leg at the tank shell shall be cut (50 mm ) interfacing with rat hole.
Please tell me ,where this 50mm is specified.(API650 ?)
Please confirm my hand sketch is correct or not?
Note; Only half portion
of the stiffener is shown in the sketch for easiness.
We want to use the below shown type of stiffener ring in staorage tank.
How could I provide rat hole in this stiffener.
If so what happens at the intersection of stiffener and shell vertical joint...
