GWUT Technology

The Advanced Inspection Services Department offers both Teletest Focus® and Guided Ultrasonics G3® in our line of services.

Teletest Focus®
The Teletest Focus® is the third generation in Guided Wave technology manufactured by Plant Integrity (TWI).

	Generates torsional, longitudinal and flexural waves Pipe sizes from 2" to 48" can be tested Clamped and inflatable for minimal set up time Most testing can be performed in service Low voltage battery for up to 12 hours of testing Utilizes Focus® software to enhance anomaly classification

G3®
The G3® is the third generation Guided Wave technology manufactured by Guided Ultrasonics LTD.

Generates torsional, longitudinal and flexural waves Pipe sizes from 2" to 48" can be tested Clamped and inflatable rings for minimal set up time Most testing can be performed in service Low voltage battery for up to 12 hours of testing Utilizes Wavemaker® software to enhance anomaly classification

Enhanced Focusing Capability (EFC) and FOCUS®
This capability allows the technician to "focus" in and isolate areas of concern to better distinguish location, size and circumferential extent. Each system uses these techniques to yield greater reliability and increased production.

EFC enables the technician to determine orientation of the symmetry plane. New developments have extended this capability so that more precise orientation information can be displayed in an unrolled pipe display that mimics a C-scan plot of the pipe wall. The contour map shows the orientation and distance of any pipe features.

FOCUS® makes it possible to focus ultrasound at any point both along and around the pipe, thus improving flaw detection capability. It also means that it is possible to determine the approximate circumferential extent and depth of any flaw that has been identified using the equipment in its original screening mode. Using the Version 2 software, it is possible to switch from screening mode to focusing at a specific distance from the tool.
