Ultrasonic corrosion monitoring is a non-intrusive (non-invasive) technique for mapping material thickness. The technique can be used to identify variations in material thickness due to corrosion or other degradation phenomena, graphically portraying problems such as stress corrosion cracking (SCC) or hydrogen-induced cracking (HIC).
Data can be stored as a digital image for subsequent analysis, and it can also be used as a reference for future inspections, using colour coding to show differences in thickness readings.
Applus+ is a trusted partner in corrosion monitoring, offering its own developed and patented methods, techniques, and solutions to every client.
Often the industrial assets, equipment, installations, and plants are exposed to general corrosion. This is the gradual destruction of a material common in metallic and non-metallic assets caused by interaction with chemicals, electrochemical, friction or other environmental causes. Applus+ helps clients mitigate costs by preventing degradation of an asset or equipment over time, thus problems can be addressed before it reaches its critical point.
When monitoring an asset, we observe the progress, quality, and integrity of your asset over a period of time. The discontinuity in materials is regularly shown on other surfaces or irregularities in the wall thickness. The regular data collection helps experts to consult on which maintenance work needs to be performed to mitigate damage. Clients frequently prefer regular monitoring to enhance operational reliability and prevent rapid degrading, avoiding failure and maintain reliable and safe operation for people and environment.
Next to all conventional Non Destructive Testing (NDT) methods, Applus+ uses the following screening techniques:
Methods for detailed quantification of indications:
Special Solutions:
Applus+ helps mitigate risks, ensure integrity and safety of assets, and contribute to a successful HSE program for people and the environment.
The technique is used in a wide range of industries. In the oil and gas industry, for example, it is used for the in-service inspection and characterisation of corrosion in pipes, storage tanks, and vessels. Proper monitoring is also necessary for boilers, crude oil systems, water systems, flow lines, storage tanks, vacuum towers, and cooling systems, to prevent leaks, and failures and contribute to high performance and reliability.
Safety: As equipment and assets age, they become more sensitive to corrosion. This effect should be properly monitored to avoid expensive replacement costs and accidents to people and the environment.
Cost reduction: Damaged equipment or assets cause massive costs. Corrosion monitoring helps avoid expenses by enhancing their lifetime.
Improved Efficiency: The operational reliability can be improved by:
If corrosion is left unmonitored, it can cause structural failure of assets, costly repairs and contaminated products, enhancing safety risks to personnel and subsequent environmental damage.
