Hi! I am in need of some expertise. I have a section of piping that has been inadvertently submerged in water for several years (probably 40+ years). The pipe was discovered recently with lots of general corrosion on its surface in the form of loose scale and rust. The remaining pipe thickness must be found. The fear is that if we try to clean a section of the pipe to perform a UT Thickness reading may puncture the pipe. We have some knowledge of others in our industry who have had this happen. The question I have is what other inspection methods can I use to determine the remaining wall thickness without doing any surface cleaning of the loose scale or rust. Any help would be appreciated.
