sheer wave ultrasonic testingDue to severe thermomechanical loads imposed by their normal operations, coke drums typically experience numerous cracks and bulges during their lifetime. The methods that are relied upon to inspect drums have limitations that must be understood in order to avoid costly loss of containment and unplanned shutdowns. In this presentation, we review three case studies in which limitations associated with three different inspection methods have led to two major leaks and one near-miss.
