Wall Thickness Measurement - NDT
Wall Thickness Measurement Lior PICK 1, Ron PINCU 1, Rachel LIEBERMAN 1 1 Vidisco Ltd.; Or-Yehuda, Israel Phone: +972 3 5333001, Fax: +972 3 5333002; e-mail: Abstract Frequent NDT inspection in pipes seeks to assess if the pipe wall Thickness has been altered (eroded/corroded) over time. Even the slightest change can affect the pipes ability to withstand pressures and meet relevant operation requirements. In this article we review various complications regarding wall Thickness Measurement when using Digital Radiography. We discuss the amount of material to be penetrated for good inspection, the Blooming Effect (penetration vs. saturation), the implications of magnification (distortion and Unsharpness) and more.
Keywords: Digital Radiography, NDT X-ray, Pipe Inspection, wall thickness measurement, Tangential and Double Wall Techniques . 1. Introduction – NDT Pipe Inspection . 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. Over time, corrosion ...
