Storage Tank Surveys 
SPI NDT Limited are able to provide a complete inspection
service to survey above ground storage tanks. Surveys can be undertaken
to the requirements of EEMUA 159 and API. We have experienced qualified
Technicians to perform the surveys. SPI carry out the tank surveys incorporating
the latest Non Destructive Testing (NDT) techniques including Slofec, Magnetic
Flux Leakage (MFL), Eddy Current and Remote access Ultrasonics.
NDT Techniques utilised on tank surveys:
• Slofec
• Magnetic Flux Leakage
(MFL)( Pictured left)
• Eddy Current
• Remote access ultrasonic crawler (Pictured
below)
• Ultrasonics (UT)
• Magnetic Particle Inspection
(MPI)
• Dye Penetrant Inspection (DPI)
• Vacuum Box Testing
• Bubble Soap Testing
SPI NDT Limited produces a detailed report for each individual tank.
The reports contain CAD drawings and tables to aid easy interpretation
of results. The report will give a thorough condition report of the
tank, recommending any repairs/alterations to ensure the tank is acceptable
to the relevant standard and will also inform the client of when the
next survey will be due. SPI will perform full or part surveys and
are willing to visit the tank initially to advise on survey preparation
and scope.
