AlphaGage+ Corrosion


Overview

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. 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

AlphaGage+ Standard Features

  • Echo-to-Echo functionalities
  • Up to 27 Hour battery life (high-capacity re-chargeable battery pack via the USB port)
  • Change colour and vibrate on alarm (ideal for inspections in loud environments)
  • Wide thickness range
  • Inches, mm or μSec
  • Velocity mode
  • Fast Min/Max mode to display actual thickness and minimum and maximum at the same time
  • Gain, range, rectification, blank adjustments with live waveform
  • Datalogger 2 Gb micro SD card standard expandable to 32 Gb
  • Datalogger interfaces with Microsoft Excel
  • Multiple languages

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.

Aircraft manufacturers have very demanding specifications when it comes to non-destructively measuring the wall thickness of aircraft parts.

Paint on Various Substrates

Paint on Various Substrates

Most conventional coating thickness gages using eddy current or magnetic induction or other magnetic techniques can easily and accurately measure the thickness of paint on metals such as that on an automotive hood. They cannot measure paint on non-metal materials such as plastic bumpers, composites, wood or concrete.

Inspection of Nozzles using the Veo3 and Scannner

Traditional UT inspection is time consuming, creating a scan plan and then performing the scan using multiple transducers. When using the Veo3 and Nozzle Scan the set ups can all be done offsite, thereby substantially reducing and easing site work.
