¨    are fundamental elements in the supply and processing chain.

¨    Products, as well as atmospheric and service conditions and age make tanks very risky for environment.

¨    Production needs make tanks very difficult to be put out of service.

Advanced NDT proposed by Procontrol for Above Ground Storage Tanks are the following:

•         ACOUSTIC EMISSIONS in-service inspection of flat bottom storage tanks.

•         MAGNETIC FLUX LEAKAGE floor corrosion survey of above ground storage tank

•         MAGNETIC RADIO CONTROLLED TROLLEY for tank (shell and roof), and column thickness gauge survey.
