Abstract

One of
the major field NDT areas is pipe inspection, which involves testing for
corrosion and erosion as well as examining the quality of welds in pipes. In
order to perform of the wall thickness measurements that include pitting, we
can use one of the two following techniques: Tangential Technique and Double
Wall Technique. In this study, carbon steel pipes which have 2, 3, and 4 inch
diameter were irradiated from 1m by Gamma-Ray, besides, their histogram were
analyzed via Tangential
Technique for different periods. Furthermore, the results were compared by
gathered results which measured by Ultrasonic Test.
