The oil and gas industry uses nondestructive testing (NDT) techniques to ensure the safety, reliability, and performance of its products and operations. Oil and gas NDT is the application of NDT methods and techniques in the oil and gas industry, to inspect and evaluate the structural integrity, serviceability, and quality of oil and gas components, materials, and systems.

Oil and gas NDT plays a critical role in the design, manufacture, maintenance, and repair of oil and gas components and systems, including pipelines, tanks, vessels, and other systems. Oil and gas NDT is used to detect and diagnose defects, flaws, and other imperfections that can affect the safety, performance, and durability of oil and gas components and systems.

Oil and gas NDT typically involves the use of advanced and specialized NDT methods and techniques, such as radiographic testing, ultrasonic testing, eddy current testing, magnetic particle testing, and liquid penetrant testing. These methods and techniques allow oil and gas NDT technicians to inspect and evaluate the internal and external surfaces, structures, and properties of oil and gas components and systems, without causing any damage or disruption to their function and operation.

Oil and gas NDT is performed by qualified and certified NDT technicians, who have the skills, knowledge, and experience to apply the appropriate NDT methods and techniques, and to interpret and evaluate the results of the NDT inspections. Oil and gas NDT technicians typically work in oil and gas manufacturing and maintenance facilities, and are responsible for ensuring the quality, reliability, and safety of oil and gas products and systems.

Oil and gas NDT is regulated by national and international standards and guidelines, such as the American Society for Nondestructive Testing (ASNT) and the European Committee for Standardization (CEN). These standards and guidelines provide requirements and guidance for the application, performance, and evaluation of oil and gas NDT, and are used to ensure the consistency, reliability, and validity of oil and gas NDT inspections and results.
