Quality Control

Image of Tubing Being Inspected After Inertia Welding

Full length tubes are inspected using ultrasonic inspection, while the upset ends are tested with a wet magnetic particle inspection. This inspection is carried out after the upsets are machined to the required dimensions. These tests guarantee that the drill pipe is free from defects.
