Paper: Non Destructive Inspection of Oil Country Tubular Goods Why When

Deep holes and high pressures with their related problems have created a demand for better quality tubular goods unknown but a few years ago. The author outlines recent approaches to inspecting. However, no single non-destructive test can be expected to reliably measure all the properties. Further, the inspection must insure adequate service life, and it must have a proven correlation between the properties inspected and the performance properties of the pipe. Defects and defect evaluations are explained along with their effect on pipe quality.
