Advanced NDT

Advanced NDT Technologies provide an innovative solution to many unique and difficult geometries and applications. Services range from ASME code-compliant weld examinations to the detection of in-service defects in of Piping, Forgings, Tanks and Pressure Vessels. Phased Array (PA), Time-of-Flight Diffraction (Tofd) and other Advanced Techniques are valuable tools that have great benefit. Our specialty is complex geometries and Advanced PA and Tofd.

Automated UT Corrosion mapping can be a valuable corrosion assessment tool providing an image (C-Scan) of the affected area in conjunction with Burst Pressure Calculations (B31.G, MB31G and Effective Area Assessment). AUT in Lieu of Internal Inspections can provide significant cost savings by performing condition assessment safely from the outside even while the equipment is in service. Unnecessary vessel entries can be avoided along with associated hazards and inconveniences of shutting down equipment. This service is valuable for preventive maintenance and is an effective means of detecting problems before shutdown.
