Bend Flexibility Factor with External Pressure
Bend Flexibility Factor with External Pressure
(OP)
Hi all,
ASME B31.4 gives a correction factor for the flexibility factor for bends when those are subject to an internal pressure (even if it doesn't specifically say "internal" pressure I deduce it from the fact that ASME B31.4 is mainly a piping code). Internal pressure decreases the flexibility of the bend or in other words increase the stiffness. My question is: would it work the other way round when the bend is subject to a significant external overpressure felt for example by an empty pipe in deep water?
Many thanks
