This report describes the present state of development of the ultrasonic pipe inspection vehicle being jointly developed by C.W. Pope and Associates and the Centre for Industrial Control Sciences at the University of Newcastle, Australia. The present aim is the evaluation of unpressurised pipelines to record areas of stress corrosion cracking (SCC) at relatively low cost and with minimum sophistication.The report addresses the suitability of ultrasonics in detecting stress corrosion cracking, outlines the system developed to date, and presents results and discussion from the laboratory trials ...
This report describes the present state of development of the ultrasonic pipe inspection vehicle being jointly developed by C.W.

The present aim is the evaluation of unpressurised pipelines to record areas of stress corrosion cracking (SCC) at relatively low cost and with minimum sophistication.The report addresses the suitability of ultrasonics in detecting stress corrosion cracking, outlines the system developed to date, and presents results and discussion from the laboratory trials in which the vehicle has been run in four samples of pipeline containing SCC.
