In the continuing effort to establish the viability of acoustic emission monitoring as a means of or as an aid to determining the integrity of a pipeline , a new opportunity to study the technique was afforded by a recent test conducted by The…
Follow-on work to evaluate the Kaiser effect and detecting acoustic emissions from fatigue cracks, stress corrosion cracking, and corrosion pits in pressurized pipe sections.
Assesses the capability and reliability of acoustic emissions inspection for the integrity analysis of gas transmission pipelines. The evaluation program consisted of placing various types of discontinuities in a one-mile section of
This work acquired and analyzed simulated acoustic emissions waveforms from pipelines in three series of field tests. The purposes of the analyses were to verify the accuracy of an analytical model of acoustic emission propagation in pipelines to…
Controlled defects of three different types were monitored with acoustic emission during six (6) hydrotests of a 5450' length of disused gas transmission line. AS was measured with ten (10) sensors spaced at 500' intervals, backed up by two (2)…
Evaluates pipeline acoustic emission data gathered with the intent of detecting the development of pipe cracking. The primary objectives being to acquire data to verify the usefulness and accuracy of an analytical model of the acoustic emission…
Describes the result of acoustic emission monitoring to detect stress corrosion cracking by the Pipelines Authority of South Australia. These tests took place on the 21st and 28th April, 1983.
The objective of the project was to evaluate the current applicability of acoustic emission field testing (AEFT) to the inspection of buried gas-transmission lines. This report is comprised of four major sections and for each of these sections there…
This report describes the development of an analytical model to generate synthetic acoustic emission (AE) propagating in a buried gas transmission pipeline in response to a source. The sources are assumed to be transient forces acting at a point in…
