Some of the industries that are best served by phased array technology are; oil and gas pipelines, storage tank facilities, fabrication, water facilities, power plants, railroad, and structural.
High-resolution discontinuities and ultrasonic thickness mapping of complex shapes with changing geometries, such as elbows, is very challenging. To address such applications, a variety of phased array probes and scanners can be used to access restricted areas.
Some advantages of Phased Array or PAUT, are the following:
- Quicker set up, test cycles, and reporting
- Digital record that is easily accessible with the ability to share data via email
- No radioactive source or additional safety hazard involved
- Ability to test in-service/product filled assets
- Does not affect plant equipment such as sensors and level indicators
- Ability to size multiple planes
- Better accuracy for flaw location
- Better sensitivity to planar flaws which are more detrimental to the part
- No barricades or removal of personnel during inspection
- Ability to focus at different depths electronically
- Complete weld coverage inspections
- Code Accepted
The non-intrusive capabilities of this scanning technology can be quite an asset during a down production tie-in or shutdown scenario by saving very valuable time. A qualified Phased Array technician possesses the ability to analyze data real-time to provide a pass/fail result within minutes of the scan being completed.
