This project developed compact, lightweight, prototype Electro-Magnetic Acoustic Transducers (EMATs) and studied guided waves for defect detection, classification, and characterization in cast iron and steel pipes. Through lab testing, design, and…
The objective of this project was to increase the guided wave power of the magneto-strictive sensor (MsS) technology so that the test range of guided wave achievable on pipelines could be further extended.
Field evaluation of a prototype eddy current-based technology to evaluate single-stress corrosion cracks in lengths greater than 0.3 inches and depths greater than 0.03 inches.
In this project, Intelligent Automation, Incorporated (IAI) and Oak Ridge National Lab (ORNL) propose a novel and integrated approach to inspect the mechanical dents and metal loss in pipelines. It combines the state-of-the-art SH wave…
This study was undertaken to determine the economic value of current and future project developments in the Non-destructive Evaluation Program at the Gas Research Institute in conjunction with PRCI.
Southern Gas Association report presents the results of a study of the methods and techniques which were considered to economically and practically perform internal inspecion of pipe in service. Methods evaluated include ultrasonics, radiological,…
As pipeline operators continue to find pipeline degradation in the form of crack-like defects associated with stress corrosion cracking (SCC), having standardized and robust Non-Destructive Examination (NDE) procedures is essential to ensuring the…
In-line inspection (ILI) is often used to estimate failure pressure from anomalies as part of the integrity management of pipelines. The goal of this project is to improve failure pressure estimates of stress corrosion cracking (SCC) colonies by…
The presence of hard spots, a localized confined region of relatively higher hardness, cause pipelines to be prone to crack initiation and hydrogen embrittlement. Early detection and mitigation of hard spots following plate manufacturing are…
