PAUT (Phased Array Ultrasonic Test)

Thai NDT Indonesia offers fully code compliant Phased Array Ultrasonic Testing (PAUT) as a replacement to on-site radiography.

Developments in construction codes have allowed PAUT to be used as a direct replacement to Radiography on piping butt welds to meet the quality control requirements of ASME B31.3 and B31.1 and numerous European standards.

PAUT can be worked towards both workmanship and Engineer Critical Assessment (ECA) acceptance criteria, with data being suitable for accurate sizing and defect characterization. PAUT enables reduced inspection time by simultaneously collecting multiple angle ultrasonic data in a one pass scan from either side of the weld.

Typical inspection rates are between 15-20 butts per shift. By ensuring accurate scan plans and specifically designed techniques all construction defects are readily detected, sized and sentenced accordingly.
