Alphagage+ Corrosion HIDDEN
As a primary inspection tool for corrosion assessments, the Sonatest AlphaGage+ instrument uses dual element transducers in a Pitch & Catch configuration to measure accurately the remaining wall thickness of metal structures subject to corrosion.
Overview
Dual element transducers have a transmitting element and separate receiving element located side by side, the use of Pitch & Catch reduces any measurement problems which may result from material surface issues.
This product is a key tool to inspect ageing assets and solve problems in many industries but especially, Oil & Gas or Petrochemicals.
Typical applications include:
- Metal pipe works
- Pressure vessels
- Structural parts
- Storage tanks
Features
True Thickness (under coating)
When a metal surface is protected by anti-corrosion paint or coating, true wall thickness measurement using Echo-to-Echo function is a key feature and available on all AlphaGage+ models.
Field Upgradable Features
Upgradable in the field, the AlphaGage+ is a flexible solution as it can be fully loaded from the start or upgraded anytime later by easily activating software options when required.
Data Logger (B-Scan)
Thickness readings with ID location for corrosion mapping or profile assessment and send readings to Microsoft Excel™ for further asset maintenance evaluation.
Live Waveform (A-Scan)
Display live A-scan for echo verification and real time control of acoustic range, rectification, gain and blanks or combine the A-Scan with B-Scan view for even more detailed analysis.
