Crevice Corrosion in a Subsea System — Aspect Before Analysis

Schematic drawing presenting the longitudinal section of the shell plate (sample removed from the boiler), at the position of the fillet weld (sealing weld) with a tube,  where surface welding repairs created conditions for cracking the base material in a transgranular morphology. Several cracks were identify starting from the steam drum internal surface.
