Problem:

For the bend flexibility calculation (k) from NB-3686.2 where are the pressure (P) and youngs modulus (E) values taken from for the calculation?

Solution:

Per ASME NB-3686.2, Pressure (P) is taken as the internal pressure of the pressure stiffening case selected. The elastic modulus (E) is based on the hot modulus selected. Both settings are located on the analysis sets dialog.

Note: if pressure stiffness is set = none than yes P = 0.
