we have had some small (1"nb & 1/2"nb)diameter nozzles (A106/ A333 Gr6)damaged in transit due to the nozzle being bent. My question, is there a limit to the amount the nozzle is bent before you need to replace it or attempt to straighten it mechanicaly by heating.

Damage to small nozzles
- Thread starter bigbro

Is this on a new pressure vessel? Apparently, this is an alignment nonconformance issue and IF I were the Owner's Engineer, I would request detailed measurements of the current nozzle and have you perform surface nondestructive testing (NDT).
You have two options; either replace them or locally weld repair them, if the surface NDT is acceptable, and machine concentric.
