During manufacturing, the cladding inside heavy wall reactors, made of 2¼Cr-1Mo-¼V and operated with high-temperature and high-pressure hydrogen, is subjected to various inspections, some of which are also repeated after the final heat treatment (PWHT) and after the hydraulic test. Cladding inspections can be divided into two groups: surface inspections and volumetric inspections.

The first group includes visual inspection, liquid penetrant inspection, ferrite content inspection with a magnetic instrument, chemical analysis inspection with an optical emission or X/γ ray portable tool and contamination checks, while the second group includes ultrasonic inspection and destructive tests of the deposit, by chip removal and subsequent chemical composition analysis.

The applicable methods and the acceptance criteria required by the manufacturing code or normally requested by the main customers will be analysed for each inspection.
