Maya’s eyes flickered. “Good. Pulsed eddy current is correct. But you didn’t answer the first part. You don’t just remove cladding in winter—you create a temporary heated enclosure. Otherwise, removing the insulation exposes the cold shell to air, and you get rapid condensation, then ice, then brittle fracture risk. The updated questions aren’t just about what to do, but how to do it safely.”
Key points: difference between set values and code calculation; thickness equation use; consideration of insulation and localized corrosion; documentation. Follow-up: How would you select corrosion allowance for sour service? static equipment interview questions updated
