ACFM

SIr,

I understand that ACFM is a technique for finding the surface cracks. Where is it being used? Can it be used in power plants during shutdown for condition assessment ? What sort of surface cleaning is required ? Anybody using the technique for in service inspection ? If any literature source is available pl indicate

You are correct ! The equipmen are use to detect surface breacing cracks offshore ,onshore and could be used at powerplants as well. ACFM have data storage facillities for your scans and sizing opportunities.The requirement for cleaning will be as for eddy current. However the ACFM method is not the fastest method avilable and it takes a trained operator to do a efficient and qualifyed job. In normal job situations where you dont have requirements for data storage i would not choose ACFM but rather more conventional eddy current equipment.

Re: ACFM
Excellent information on ACFM is available from Technical Software Consultants web site http://www.tscuk.demon.co.uk/tschome.htm

ACFM is certainly widely used on power plants. It has advantages of being able to work through thicker coatings than conventional eddy currents or MPI, thus reducing cleaning requirements, and can depth size cracks. For more information, please refer to our web-site.
