Experience of AUGUR-T system application on oil and gas industry objects

In this article ultrasonic inspection modes of the pipelines base metal and welded tee with overlays internal welded joints nozzle-shell are presented. The base of these modes is the ultra-sound waveguide propagation effect and coherent data processing methods. The results received by the automated ultrasonic inspection on gas and oil transport objects are presented. Efficiency of con-sidered inspection modes is shown.

Keywords: ultrasonic inspection, welded tee, internal welded joints nozzle-shell, coherent data processing, waveguide propagation effect.
