ABSTRACT:
There is disclosed a process for cleaning the interior wall of a metal vessel or pipe comprising flooding or turbulently impacting the interior wall of said vessel or pipe with a strongly alkaline or strongly acidic cleaning fluid, simultaneously measuring the conductivity of the cleaning fluid between two electrodes located in the interior of said vessel or pipe and terminating said flooding or impacting when the measured conductivity has been substantially restored to the level measurable with clean electrodes. There is also disclosed an apparatus for performing the process.
