ACFM (Alternating Current Field Measurement)
ACFM is in use worldwide in almost every industrial
sector. It
is particularly well used for in-service inspection as an alternative
to MT / PT . ACFM is ideal for crack detection
at welds, through coatings and has the added advantage of producing crack
depth information. Therefore ACFM can provide cost benefits over conventional
surface testing methods such as MT/PT where the removal of coatings and
re-application is costly.
SPI NDT Limited uses the AMIGO Crack Microgauge system manufactured
by TSC Inspection Systems, this is a rugged site inspection system rated
to IP54. Operators are qualified to CSWIP requirements and carry out
inspection to TSC operating procedures and the requirements of ASME V
Article 15 where required.
Typical structures that are inspected with ACFM include cranes, bridges, theme park rides and lamp-posts. Ships offer many opportunities for ACFM inspection. The ability of ACFM to inspect through paint, and even underwater, mean that ship hulls can be inspected without having to enter dry-dock. Many components in the petrochemical industry are coated either in paint, lagging or more exotic materials such as zinc or fire protection materials
