FURTHER DEVELOPMENTS IN ULTRASONIC INSPECTION OF PIPELINE GIRTH WELDS

Authors E.Ginzel and M.Hoff

Abstract

Ultrasonic Inspection has been widely used in Canada since the early 1980's for inspecting Mechanized Girth Welds. In 1993 TransCanada PipeLines Limited (TCPL) became the first North American company to use ultrasonics as the primary nondestructive testing (NDT) method on a pipeline construction project. Further enhancements to the ultrasonic systems have increased the reliability, speed and evaluation capabilities of the systems presently approved by TCPL. A review of the systems and the enhancements is presented in this paper.
