Galvanized steel pipe is protected by a layer deposited by hard water, but may suffer corrosion in soft water. Presented are case studies of corrosion in galvanized water piping in a stadium, hotel, and county government building. Details of corrosion mechanism and mitigation strategies are also discussed.
Service life of any weapon system depends upon factors that impart long-term durability and robustness to its structure and subsystems, while sustaining its functional properties. The paper describes basic principles and guidelines on corrosion control and rules that could be easily followed to ascertain some specified service life and reduce total ownership costs.
Results of inhibitor performance at slug flow in a 101.6 mm inner diameter horizontal pipeline. Electrochemical Impedance Spectroscopy (EIS) and scanning electrom microscope (SEM) techniques are used to reveal that the strong bubble impact, high shear stress and turbulent intensity are the reasons for a poor performance of inhibitor.
