Interference between stiffener rings and saddles
Interference between stiffener rings and saddles
(OP)
Can someone please offer guidance on the installation of external stiffening rings that would intersect with either nozzles or support saddles? Section UG (VIII-1) states that the rings shall extend completely around the circumference of the cylinder. But, as long as the required moment of intertia is satisfied at the gaps of the stiffener ring, why not allow gaps for external rings. Rules are given for gaps with internal rings.

In the case of a nozzle, I would personally avoid a ring crossing it: you can always put two rings in place of one.

Echo prex on nozzle though. I wouldn't.

Are you modifying an existing vessel in order to provide a "vacuum rating" ??
