Pipeline inspection is a process that involves evaluating the condition, integrity, and performance of pipelines, using various nondestructive testing (NDT) methods and techniques. Pipeline inspection is used in the oil and gas industry, as well as in other industries that use pipelines to transport fluids, gases, and other materials.

Pipeline inspection is performed to ensure the safety, reliability, and performance of pipelines, and to detect and diagnose defects, flaws, and other anomalies that can affect the pipeline’s operation and serviceability. Pipeline inspection is typically performed on-site, without the need to disassemble or interrupt the pipeline’s operation.

Pipeline inspection typically involves the use of advanced and specialized NDT methods and techniques, such as ultrasonic testing, magnetic flux leakage, eddy current testing, and radiographic testing. These methods and techniques allow the pipeline inspector to evaluate the internal and external surfaces, structures, and properties of the pipeline, and to provide detailed and accurate information about the pipeline’s condition.

Pipeline inspection 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 inspections. Pipeline inspection technicians typically work in oil and gas facilities, and are responsible for ensuring the quality, reliability, and safety of the pipelines.

Pipeline inspection 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 pipeline inspection, and are used to ensure the consistency, reliability, and validity of pipeline inspection inspections and results.
