If shell distortion is found at a nozzle, what should be inspected next?

When shell distortion is observed at a nozzle, the immediate subsequent step in the inspection process focuses on identifying potential structural issues that could arise from the distortion. The correct next inspection involves checking for cracking on all nozzle welds and adjacent shell welds. This step is critical because the distortion may have induced stress at these junctions, leading to cracks that could compromise the integrity of the pressure vessel.

Nozzle welds and the welds connecting the nozzle to the shell are particularly vulnerable areas. If any cracking is present, it could signal a significant concern for the vessel's operational safety and structural integrity. Such issues need to be addressed promptly to prevent failure and ensure compliance with safety standards.

While adjacent piping supports, internal components, and external protective coatings are all relevant to the overall inspection of a vessel, they do not directly address the immediate concerns raised by the shell distortion at the nozzle. Thus, focusing on the welds surrounding the nozzle is the most logical and critical next step in the process.
