Metallurgical Factors Affecting Microbial Colonisation and Corrosion of Drinking Water Network Materials

Abstract

The present work reports the studies performed to investigate the influence of some metallurgical factors in the microbial colonisation and corrosion of drinking water network materials. Cold rolling process applied to row materials submitted to drinking water dynamic tests seems not to affect substrata areas colonisation distribution as compared to as received condition of tubing materials. However, samples exposed to hydrodynamic and static tests with three different accumulated plastic deformation show diverse magnitude of localised attack but non-correlative with the substrata surface energy.
