About Margan

 

Margan is the world expert in on-line inspection and monitoring of critical piping systems, pressure equipment and structures by its own pioneered and developed Quantitative Acoustic Emission Non-Destructive Inspection (QAE NDI) technology.

 

Innovation

 

Since 1994 Margan has introduced a number of inspection concepts and technologies that are about to revolutionize the way various industries inspect their critical components and structures. Particularly in the power industry, Margan has developed:

  • QAE NDI technology for on-line early flaw detection, their typification, assessment and quantitative monitoring in critical steam piping systems and pressure equipment during their normal operation.
  • Monitoring concept and rope access installation that made this concept applicable.
  • Inspection and monitoring of cold reheat lines subjected to thermal shocks.
  • Detection and evaluation of plant operation conditions and dynamic events causing flaw origination and development.
  • Evaluation of dynamic hangers' performance.
  • On-line inspection of boiler headers and deaerators.
  • Technology for on-line inspection and monitoring of high chromium steel piping systems.

 

In other industries, Margan has developed and successfully applied QAE NDI technology for on-line inspection of low density polyethylene reactors, water cooling loops in nuclear power plants, glass-lined equipment, concrete and reinforced concrete structures and many other applications.

 

Experience

 

Margan is the most experienced company in on-line inspection and monitoring in the power industry. Through more than a decade of on-line inspection of high energy piping systems, Margan's QAE NDI technology has demonstrated reliable, early detection and accurate assessment of all common failure mechanisms typical for high energy piping including thermal and mechanical fatigue, creep at pre- and micro-cracking stages, cracks in hangers and many others. QAE NDI findings were validated in numerous confirmation and double blind tests.

 

In oil, gas and petrochemical industries, Margan's QAE NDI technology has demonstrated superior detectability and accurate assessment of stress corrosion cracking, caustic corrosion, fatigue, hydrogen embrittlement and other dangerous flaws types in different critical process equipment that previously could not be satisfactory inspected by other NDE methods including tradition AE. There are cases when QAE NDI has warned about impending dangerous failures before those could be identified by other available means.

 

Margan's experts were pioneers in development and practical application of acoustic emission technology for inspection of hundreds of kilometers of concrete, reinforced concrete and metal bridges, tunnels, landslide activity, and buildings after trauma, fire and other events.

 

Value

 

Margan brings a great value to the industry:

  • Safety - Improved safety of critical piping systems, equipment and structures.
  • Comprehensiveness - The QAE NDI is applied to 100% of the structure and for all common failure mechanismsat their earliest stages, in many cases long before they can be identified by other NDE methods.
  • Cost Effectiveness - The QAE NDI hardware is permanently installed on structures, and thus requires one-time installation costs.
  • This is a turnkey solution that requires no scaffold or prohibitive structure preparation. Installation is done by rope access. The cost of the baseline inspection is 50% of NDE during the initial installation and about 20% of the total cost of NDE for repetitive inspections.
  • Convenience - The QAE NDI is completely outage independent. Installation and inspection are done on running piping or equipment. No interference is required from plant personnel. The Cost Proposal is a fixed price and it is 100% of the budget. No additional costs are required.
  • Cumulative experience - The QAE NDI method has been applied to a large number of applicationsin different industries. The QAE NDI monitoring system has been installed on over 140 high energy steam lines and a large number of repetitive inspections have been performed. There has been an excellent agreement with confirmatoryNDE and metallurgical methods.
