T-ALL Inspection utilizes non-destructive testing (NDT) techniques such as ultrasonic testing (B-scan, PA, AUT), radiographic testing (RT, DR), magnetic particle testing, penetrant testing, and eddy current testing, as well as physical and chemical testing methods like spectroscopy and metallography, to accurately identify and evaluate defects in the circumferential welds of both new and in-service pipelines during manufacturing and operation. This ensures the safe and reliable operation of oil and gas pipelines.
