    Materials Selection & Design: Corrosion Analysis of a Newly Installed Family Heating System


    Author(s): Zhanjun Guo, North China University of Water Resources and Electric Power; Zhiliang Chen, Chinese Academy of Sciences

    A corrosion analysis of a newly installed domestic (residential) heating system was carried out after it suffered corrosion attack in less than three months of operation. The makeup water had a high salt concentration and a low pH value. In addition, the make-up...

    Cathodic Protection: An Alternative View of the Cathodic Protection Mechanism on Buried Pipelines


    Author(s): R.A. Gummow, S. Segall, and D. Fingas, Corrosion Service Co., Ltd.

    The conventional understanding of the cathodic protection (CP) mechanism is illustrated in the definition of CP arising from the research of Mears and Brown in 1938. That is, CP is complete when the corrosion cell cathodes are polarized electronegatively to the...

    Attenuation of Forced Drainage Effects on Long Uniform Structures

    Published: February 01, 2018
    Author(s): Robert Pope, Bell Telephone Laboratories

    When forced drainage is applied to an underground metallic structure to provide cathodic protection, the greatest effects on the structure and earth potentials occur in the vicinity of the drainage point and anode. These effects taper off as the distance from...
