A cost effective solution for corrosion detection and monitoring of insulated components

Page last modified
Wednesday, September 8, 2021 - 23:00

SONOPEC is designed to avoid leaking assets, caused by the hidden phenomenon corrosion under insulation (CUI), collapsing sphere legs and breaking down offshore risers and conductors.

SONOPEC is a tool designed for the detection of corrosion under insulation, coating, bitumen, concrete fire proofing, marine growth etc. It can be used manually operated and it can be mounted on remote under water operating vehicles (ROVs).


No loss of production because of leaking assets
Reduced costs, as no insulation removal is required
Reduced unexpected shutdown
Highly sensitive for detection of flow accelerated corrosion in power plants
Tool available for purchasing by 3rd parties
Electrical tracing needs to be switched off


Accuracy + / - 5%
Areas of Application Corrosion under insulation | Corrosion under concrete fire proofing | Flow accelerated corrosion | Storage tanks annular plates online examination | High temperature applications | In-service corrosion monitoring | Inspection of heavily corroded equipment
ATEX certified No
Capabilities Remaining wall thickness measurement, lift off measurement, automated reporting. 3D data presentation, Encoded measurement X/Y, dynamic mode scanning.
Certifications / licences Training courses for tool and application are available at TÜV Rheinland Sonovation.
