DACON
AUTOMATED CORROSION MAPPING

FOR ALL YOUR INSPECTION NEEDS

     

DACON automated corrosion mapping uses a high-performance Ultrasonic Flaw Detector with a Full Imaging System built in. The system is capable of fully automated high accuracy defect mapping and recording. Ideal for tasks from corrosion mapping to aerospace inspections on composites.

DACON uses the RAPTOR flaw detector which is an all-in-one high resolution ultrasonic thickness gauge, ultrasonic flaw detector and imaging flaw detector capable of driving a range of manual and automatic scanners.

DACON uses the RCA-10 & RCA-18 scanners which are capable to automatically scan large surfaces on pressure vessels, tank or piping of all diameters at high speed.

Advanced Imaging Capability

The system comes with a full suite of software functions for further analysis of the results, including B-Scan sections, 3D images, statistical tools for defect sizing and much more.

Advantages

• The software functions and data presentations will allow for easy analysis, resulting in precise and repeatable inspection for monitoring of critical locations.
• Being fully automated, accessibility to remote locations can be achieved from the ground without the requirement for scaffolding.
• Large areas area’s can be scanned at high speed and with high accuracy and repeatability.
