초록
The corrosion of pipe materials dramatically proceeds due to several factors (e.g., temperature, flow rate, concentration of chlorine). In particular, seawater leakages can unexpectedly and suddenly occur in seawater pipes because of coating failures, cracks in the welding area, and localized corrosion. These problems can repeatedly occur in the absence of an effective protection technique. In this study, we performed electrochemical and on-site tests for the application of cathodic protection on the inner surface of seawater pipes. We measured several parameters, including the corrosion rate, corrosion current density, optimal cathodic protection potential, and range of cathodic protection current density necessary to maintain the cathodic protection potential. Furthermore, we determined the effects of corrosion prevention on some pipe specimens by registering the cathodic protection current density, cathodic protection potential, and state of the pipe’s inner surface under various flow rates.
Abstract
The corrosion of pipe materials dramatically proceeds due to several factors (e.g., temperature, flow rate, concentration of chlorine).

In this study, we performed electrochemical and on-site tests for the application of cathodic protection on the inner surface of seawater pipes. We measured several parameters, including the corrosion rate, corrosion current density, optimal cathodic protection potential, and range of cathodic protection current density necessary to maintain the cathodic protection potential. Furthermore, we determined the effects of corrosion prevention on some pipe specimens by registering the cathodic protection current density, cathodic protection potential, and state of the pipe’s inner surface under various flow rates.
