MONPAC
Acoustic Emission (AE) technology package for evaluating the structural integrity of metallic pressure equipment
Page last modified
April 11 2024
MONPAC™ utilises proprietary multichannel AE systems and sensors that detect the high-frequency signals resulting from active defects. The systems have sufficient speed and resolution to ensure real-time, on-screen display of all activity and indications. It provides a severity grading for defects along with recommendations for further action. Sources of interest can be located on the equipment.
Pros & Limitations
1
Rapid inspection (e.g. a 15m sphere is tested in approximately 3 days)
1
Global monitoring (100% inspection, including welds, repairs etc.)
1
Supports Non-intrusive Inspection (NII) strategies, as per DNV-RP-G103
1
Aids pre-turnaround inspection and maintenance planning
1
In-service continuous monitoring can be applied to critical assets, as per API 579
1
Meets the requirements of ASME-V article 12, EN 15495, EN 14584 and AFIAP
1
Guiding local NDT where it is needed
1
Reduction in downtime resulting from improved information about plant condition
1
Reduction in inspection costs
0
The method does not identify manufacturing defects
0
It does not give information on defect size but grades the activity and gives recommendations for the extent of any follow-up inspection
