Corrosion Damage Assessment Utilizing Special Ultrasonic Techniques, 1992 Engineering Conference Proceedings
In the pulp and paper industry, most boiler tubing and piping systems are subjected to corrosive conditions, which cause accelerated deterioration, and on occasion, premature and unantici-pated failure.
Conventional nondestructive examination techniques have proven unsuccessful in the accurate remaining thickness determination on piping systems in digesters. This is due, primarily, to geometric considerations, as well as to the capabilities and expertise of testing technicians. This paper discusses the development of an ultrasonic examination technique which uses both conventional pulse amplitude and satellite pulse response techniques to identify corrosion damage, and readily assesses the remaining wall thickness to within 0.050". It will detail the development process as well as application of the technique.
