Quality evaluation of crude oil pipeline welding joints by using NDT techniques, with a specific emphasis on X-ray radiography

Abstract

The objective of this study is to evaluate the quality of crude oil pipeline welding joints used in Zueitina oil company was performed by two methods of NDT techniques, with a specific emphasis on X-ray radiography and PAUT ultrasound. Examining the effectiveness of NDT in detecting defects and These two tools enabled to identify the causes of welding defects as well as to determine the frequency of their occurrence and to identify the most serious welding faults and defects. Both methods – technical should reveal shortcomings in technological aspect. Their use should contribute to improving the welding process of pipes in operation and to increasing the safety of piping systems.
