AUT Corrosion Mapping

Versa Integrity Group is well versed in many different areas of Automated Ultrasonics (AUT)

Being a leader and pioneer in the application of Automated Ultrasonics (AUT), Versa Integrity Group can meet all your needs when it comes to Automated Ultrasonics. When used in combination with our Rope Access division, we can dramatically reduce the cost of infrastructure to access your hard to reach areas. Please view the picture slides to the right for brief examples of the applications of Versa AUT division.

What is Automated Ultrasonics (AUT)?

AUT is any form of ultrasonics (phased array, conventional shear wave, corrosion mapping, etc.) used to determine wall loss, crack detection, laminations, and any other discontinuity that may exist in base materials and welds. The data acquired is recorded and encoded for service life trending and evaluation. We use many different computer and software packages to accomplish this goal. Below are some of the common AUT techniques that we perform for our clients:

Corrosion Mapping

This technique is used to map the interior surface of pressure vessels, piping, heat exchangers, etc. It can be used for remaining life determination or monitoring of existing corrosion problem areas to maximize the amount of time that a piece of equipment can be used before shutdown.

Encoded Weld Quality/Monitoring

This technique is used to inspect welds that are new fabrications or existing welds for defect monitoring (critical defect sizing, crack monitoring, etc.). If required, we can fully meet the requirements of ASME Code Case 2235-9, which allows you to perform Ultrasonics in lieu of radiography when dealing with certain sections of ASME fabrication.

Advantages of Automated Ultrasonics (AUT)

AUT has proven to be invaluable in shutdown planning, as you know what you need to replace before the shutdown. Additionally, we are capable of performing in-service exams in temperatures that range from -10˚f to 700˚F. All data is encoded and recorded for repeatability.
