Ultrasonic Inspection

Identify Defects and Discontinuities

Immersion UT inspectionUltrasonic Inspection, also known as UT Inspection, is a reliable method of detecting defects on or below the surface of materials and discontinuities in the wall thickness of tubing, pipe and other round stock. The test results from ultrasonic inspection services provide valuable information about the reliability of materials and products without causing them harm during the inspection process.
