This report summarizes work conducted under a contract entitled "In-Line Inspection Technologies for Mechanical Damage and SCC in Pipelines." This project evaluated and developed inspection technologies for mechanical damage and cracks in…
The project objective is to build and test an Electro-Magnetic Acoustic Transducer (EMAT) tool prototype to detect and quantify longitudinal cracks in metallic pipes. The sensor will be used to assess small diameter and unpiggable pipes containing…
This report describes the development of a computer-based log interpretation system for the processing of multichannel pipeline survey records. Project goals and objectives are. included together with functional descriptions of system hardware and…
Guidance is needed for the pipeline industry's in-line inspection (ILI) technologies as current industry practices address mainly thin-wall pipe specifications as well as spool and defect design. Heavy-wall pipe is mostly found in subsea applications…
ILI systems' testing was conducted at the PRCI Technology Development Center (TDC) using two (2) separate ILI pull tests strings with more than 120 MD specimens including plain dents, dents with corrosion, dents with gouges and dents with fatigue…
This report describes the results of magnetic flux leakage measurements performed on a larger scale in the 40 foot long joint of a 36-inch diameter buried pipe. The instrument was tested in the pipe at speeds of up to 2 feet per second and the pipe…
Development of a bench-scale electromagnetic acoustic transducer (EMAT) sensor that can be used to assess the wall thickness of small diameter unpiggable pipelines containing reduced diameter fittings and other restricting features.
An experimental study to investigate the potential of a multi-frequency eddy current technique in detecting defects in steel pipelines. This feasibility study is the first of a three-phase program for the development of an inspection pig for gas…
