Abstract
This disclosure relates to a method of and apparatus for determining the corrosion rate of metal by liquid flowing in a metallic pipe system by continuously bleeding off upstream and downstream liquid portions from a metallic pipe at predetermined rates for predetermined time periods and filtering therefrom both heavy metals and particulate metals, determining the rate of solution corrosion and cavitation-erosion of the metal from the amount of heavy metals and particulate metals, respectively, filtered from the upstream and downstream bled-off liquid portions, and integrating the difference between the upstream and downsteam determinations to obtain the corrosion rate of the metallic pipe system.
