Before I retired the cement plant maintenance supervisor (an excellent marksman/re-loader) had a lamination problem when he tried to open a hole in a cement slurry storage tank prior to repairs. The first of 4 shots went about 3/16 to 1/4 into the steel. the remaining shots enlarged the hole to about the size of a quarter but no deeper. I felt a shaped charge would do the job but was unsure about the piping and pumps being able to withstand an instantaneous but brief overpressure. Never pushed the issue. Routine procedure was to either unbolt a big door (large enough for a 1.5 yd. loader) or work a drainage hole with oxy/act torch. either way led to the employees getting well soaked with slurry. Not sure why a 8 or 10 inch flange would not have worked.
