PASS Whitepaper

IIA’s PASS inspection procedure uses proven Phased Array Ultrasonic Technique (PAUT), which is a superior technique to RT, Conventional UT, or Acoustic Emissions. PASS offers complete and accurate scans of valves without the need to disassemble pipes and valves.

IIA’s PASS techniques along with our proprietary Valve Visualization software, provides our technicians an unmatched level of information regarding performance aspects of valve integrity and also of how the valve reacts during operation. PASS methods and our software offers a complete solution for PAUT data analysis.
