Line Scanning DR Digital Imaging Technology Application on Spiral Submerged Arc Welded Pipe

Wang Hua-gon

Abstract

To utilize new type line scanning direct radiography digital imaging technology is to carry out X ray direct imaging inspection to weld on pipe ends of spiral welded pipe.Its sensitivity and distinguished rate is superior to image intensifier and reaches and exceed the level of film and can replace the existed film inspection to improve inspection rate and quality.
