Nondestructive testing techniques are increasingly applied to equipment, systems, and components to insure the continued safety and performance reliability of operating chemical plants and refineries. The various nondestructive examinations utilized include not only the conventional methods such as ultrasonic, radiographic, magnetic particle, and liquid penetrant examinations, but also techniques such as eddy current testing, pipe crawlers for internal visual pipe inspections with video cameras, infrared techniques, replication, capacitive strain gage testing, etc.
