I am relatively new to B31.3 and am finding myself running around in circles on this topic.

I have a situation where a pipe under normal operating conditions is to be displaced a small amount to adjust pipe supports.

My first question is;
Is Appendix P an option for comparing all implied stresses (pressure, thermal growth, and the induced delfection) to one Allowable SoA as per P302.3.5(d)

If this is not applicable, would I compare Sustained loads (weight, pressure) against my allowable stresses as per Appendix A, AND also my displacement stresses against equation 1a para.302.3.5(d) and if both fall below their respective limits than, than all is well?

Any input would be greatly appreicated as i dive into the realms of B31.3
