Ultrasonic Testing of Welded Joints in Polyethylene Pipe

  • Published:
Russian Engineering Research Aims and scope

Abstract

The reliability of ultrasonic testing (UST) of the quality of welded joints of polyethylene pipelines, made end-to-end with а heated tool, is considered in comparison with mесhапiсаl tests and radiography. The greatest detection of solid defects is provided bу u|trasonic inspection with the use of chord transducers (not less than 90%). When detecting defects translucent for ultrasound (lack of penetration, lack of fusion, etc.), the reliability decreases to 70–80%.
