This evaluatates the emerging phased-array (PA) automated ultrasonic testing (AUT) method and further assesses the performance of AUT and PA AUT techniques to detect and size flaws in the current pipelines with a relatively wide range of wall thickness.
Given the critical nature of pipelines and the consequences of structural failure, designers are adopting reliability and fitness-for-purpose (FFP) design methods to ensure that structural integrity can be guaranteed throughout the entire design life. The use of reliability and FFP based design methods requires the use of improved assessment...
Given the critical nature of pipelines and the consequences of structural failure, designers are adopting reliability and fitness-for-purpose (FFP) design methods to ensure that structural integrity can be guaranteed throughout the entire design life. The use of reliability and FFP based design methods requires the use of improved assessment and inspection techniques that can reliably detect and size fabrication flaws produced during construction and repair. Over the last five years, AUT has been used increasingly in cross-country and offshore pipeline construction to improve defect detection and sizing reliability. AUT inspection offers many advantages over conventional manual UT including:
