This involves inspection of used Drill
Stem Elements including drill pipe body, tool joins, rotary-shouldered
connections, drill collar, HWDP and the ends of drill stem elements.
OCTG Inspection is done with application
of non-destructive testing methods to minimize disruption to equipment and
operations. Visual, Dimensional, Ultrasonic wall thickness, Penetrant and
Magnetic Particle Testing methods are used.
