If distortion is found around a nozzle connection during inspection, what is the recommended next step?

• A. All seams and the shell in this area should be examined for cracks
• B. All horizontal welds around the tank in the course that contains the nozzle should be examined
• C. All vertical welds within 36 inches of the nozzle should be examined
• D. An area measuring two nozzle diameters square should be examined around the nozzle

Answer: (A)

When distortion is found around a nozzle connection during inspection, the recommended next step is to examine all seams and the shell in that area for cracks. This step is crucial because the presence of distortion indicates potential structural issues that may have arisen due to stress concentrations, operational stresses, or external factors affecting the integrity of the tank. Focusing on seams and the shell is essential because these are critical areas where failures can initiate. Cracks can compromise the integrity of the tank, leading to leaks, environmental hazards, or even catastrophic failures. By thoroughly inspecting these areas, an inspector can identify any deterioration or potential failure points, allowing for timely repairs and ensuring the continued safe operation of the storage tank. While other choices suggest inspecting various welds or specific areas around the nozzle, they do not target the critical aspect of the structural integrity related to the shell and seams, which are more directly affected by nozzle distortion. Inspecting seams and the shell provides a broader understanding of the overall tank condition in relation to the nozzle and its connections.
