Corrosion mapping

Easy To Use
Corrosion mapping relies primarily on a ‘C’-scan (plan view) image of the area under test, represented as a depth related, colour-graphic image with associated side views for easy visualisation of the internal surface condition. The user is provided instantly with a true representation of the material under test in 3 dimensions (X, Y & depth) therefore speeding the process of corrosion/erosion analysis. The colour slicing is easily set up from the colour palette provided or can be imported from a pre-defined setup file. The X & Y step resolution is defined by the operator in the scanner setup therefore screen pixel size can be varied offline with no effect on the positional accuracy of the system.

The data collected is stored on the PC and can be analysed later, printed as a report from the built-in report generator, output to a bitmap image or comma delimited file for use in other analysis tools or indeed used to physically model the surface under test. Individual scans can be joined together to form a composite view of a larger area of examination. The offline analysis tools allow the user to interrogate file data in minute detail by moving a single or multiple cursors over the image and displaying the numeric value of each pixel and differential information between the cursors.

Video Tracking or X/Y Scanner?
Positional data is controlled either by using an X-Y scanner or by tracking the probe using a video camera. Both ways of providing the positional data are set up by selecting the appropriate ‘scanner’ tab from the extensive array of scanner types. Video tracking has proved to be one of the most popular probe tracking methods used in corrosion mapping because it provides the flexibility for an operator to scan manually in any pattern that is comfortable with no motorised parts required. Easy to set up and lightweight, video tracking is ideal for work on elevated plant and when ease of movement is desired. Video Tracking is available on all our systems. 2-Axis scanners give the highest degree of positional accuracy and can be driven directly from our TD Scan and TD Focus-Scan systems which feature on-board motor drive control. The TD Pocket-Scan system provides encoder input only and therefore if a motorised scanner is required, an external motor drive control unit is required.

Proven Reliability
Since its inception our corrosion mapping software has been used on every continent to scan literally thousands of pressure vessels, tanks, pipelines and other plant. The consensus of our users is that AGR’s corrosion mapping software used in conjunction with our Pocket-Scan system is the most versatile, convenient & effective portable corrosion mapping system on the market today.
