Phased Array Ultrasonic Testing Units for Advanced Flaw Detection

Customer Case: Pipeline Weld Integrity Validation | Engineering Case

Bismarck, North Dakota

Problem
A pipeline rehabilitation project required inspection of long seam welds with complex geometry and variable wall thickness. Conventional ultrasonic testing provided limited angular coverage, increasing the risk of missed subsurface cracking and compliance exposure under U.S. pipeline safety regulations.

Solution
Phased Array Ultrasonic Testing Units deployed by Acoustic Testing Pro enabled electronic beam steering and multi-angle inspection without probe repositioning. High-density array probes produced A-scan, B-scan, and C-scan data suitable for weld root and heat-affected zone evaluation. Inspection parameters were configured to meet applicable ASME and API guidance from organizations such as the American Society for Nondestructive Testing.

Result
Subsurface cracking was detected and characterized within a single inspection pass, reducing rework scope by approximately 30 percent. A key trade-off involved higher calibration time to ensure angle accuracy across varying weld profiles.
