Project Description


Margan Technology

Since its inception, Margan has developed its Quantitative Acoustic Emission (QAE) technology to meet the needs of Non Destructive Inspection (NDI) for various applications. We combine a leading edge of technology with results focused on an approach to give us the best tools for delivering optimal NDI. Acoustic Emission is a technology that enables the setting up of tests and executing them during the plant’s operation without the need for shutdown. Acoustic Emission also covers complete regions by deploying sensors every 10-12 feet.Whenever there are developing flaws in the material, the rearrangement of atoms create a ‘shock wave’ picked up by the Acoustic Emission detectors. By doing this, our technology can sometimes ‘hear’ the onset of the flaw development even before other technologies realize. This ability to ‘hear’ nearby areas is one of its best traits.

Synergy – Quantitative, Location, and Dynamic testing

From the advent of Acoustic Emission (AE) until today, many testing applications have been developed for testing flaws in many industrial assets. It is always the greater challenge to match the right test to the right problem and the correct interpretation to the tested data. Because of this, Margan combines Quantitative Acoustic Emission (QAE), location studies, and dynamic studies into our reports. This approach enables the best screening of structural aging in the assets.Quantitative Acoustic Emission (QAE) is a mode of AE testing where the threshold detection level is lowered and calibrated in order to pick up more events that allow us to detect smaller flaws. This is accompanied by elaborate computation and analysis that enables us to detect the flaws in the early stage of development. Margan is currently the only company using QAE for HEP applications.Location studies are Acoustic Emission (AE) studies that enable locating the source of the emission by various techniques with ultrasonic time and energy considerations. This helps pinpoint out the precise location of the problematic areas.Margan combines the dynamic and constant load conditions in order to detect various types of flaws that present themselves in different working conditions.

At the basis of Margan’s approach are screen and monitoring methodologies

Almost all of non-destructive testing (NDT) methods allow testing a specified location with some scrutiny but are too cumbersome and costly to apply to a complete system. These testing methods often require a shutdown of the lines and stripping of the insulation from a fraction of the line. Operators are therefore forced to both save on NDI and to ‘guess’ where testing is needed. Margan’s technology allows initial screening of a complete line, periodic monitoring of the line, and concentrating on dealing with flaw indications only where and when they occur.

Margan “Real-Time” Technology

With the progress of technology, it is now possible to increase the physical monitoring to cover the lines constantly, and then remotely analyze the data and interpret it. This seems to be the trend of the evolution of the modes inspection. Margan technology installs real-time applications on P91/92 and other Creep Strength Enhanced Ferritic Steels (CSEF) piping which prevents the possibility of missing a fast developing flaw that would go otherwise undetected.
