Using modern nondestructive testing techniques for plant reliability; Part 1
- Thielsch Engineering, Inc., Cranston, RI (United States)
Nondestructive testing techniques are increasingly applied to equipment, systems, and components to ensure the continued safety and performance reliability of operating chemical plants and refineries. The various nondestructive examinations used 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. Special procedures may be required for the early detection of leaks applicable to vessels and equipment provided with weep holes or other leak detection systems. Examples of the applications of these various techniques and of the results detected will be presented. In all these examinations, it is important to separate those indications that represent deterioration, which potentially can lead to failures, from other inconsequential indications involving minor corrosion, superficial surface fissuring, or original manufacturing or welding defects.
