Abstract:

As a result of a successful preliminary application of ultrasonic inspection techniques in detecting corrosive pitting, an ultrasonic C-scan inspection system was developed for field inspection of chemical munitions. The system can detect pits as small as 10 by 10 mils in walls 35 and 65 mils thick. It can resolve pits separated 116 inch or greater. The system can inspect cylindrical munitions up to 4.5-inch OD, and with a minor modification, could inspect up to 6.0-inch OD. This system is being used for surveillance procedures aimed at establishing the integrity of chemical-filled munitions. It will enhance the reliability of shelf life estimates and assist in categorizing munitions for disposal.
