Assisted corrosion and erosion recognition

A system comprising:

• a memory;
• and
• a data processor, coupled to the memory, the data processor configured to perform operations including
• acquiring an inspection image of a pipe wall of an insulated pipe at a first location;
• determining, at the first location and based on the inspection image, an attenuation coefficient of an insulation of the insulated pipe at a first radial distance of the insulated pipe, an attenuation coefficient of the pipe wall at a second radial distance of the insulated pipe, and an attenuation coefficient of a fluid within the insulated pipe at a third radial distance of the insulated pipe;
• determining an inspection thickness of the pipe wall at the first location based on applying the attenuation coefficient of the insulation, the attenuation coefficient of the pipe wall, and the attenuation coefficient of the fluid to the inspection image;
• determining a wall loss measurement of the pipe wall at the first location, the wall loss measurement determined based on a difference of a nominal thickness of the pipe wall at the first location and the determined inspection thickness, the wall loss measurement characterizing an amount of wall loss in the insulated pipe at the first location;
• and
• outputting the wall loss measurement.
