A Proposal of AC Corrosion Mechanism of Carbon Steel in Cathodic Protection Condition

Corrosion, 2013
Buried pipelines are provided with corrosion prevention systems, consisting of an insulating coating and a cathodic protection (CP) system which reduces (or halts) corrosion rate.

Armor Corrosion Monitoring of a Submarine AC Cable

CORROSION 1997, 1997
Abstract After the hurricane Gilberto flattened (devastated) Cancun in September 1988, the submarine cables which supplied electricity to Isla Mujeres Island remained very damaged, and it was decided to install the new ones. In 1989, four new submarine cables were installed from Punta Sam, Cancun to Isla Mujeres.

AC Corrosion - Case Histories, Test Procedures, & Mitigation

CORROSION 1998, 1998
Abstract Literature dating back to the early 1960’s has shown that AC current can cause corrosion of cathodically protected steel under laboratory conditions. Until recently however, there has been little evidence to suggest that AC corrosion of cathodically protected structures may be of practical concern. In Ontario over

Corrosion Behavior and Evaluation Method of Pipeline Steel Under Dynamic AC Interference: A Study

Materials and Corrosion
Unlike the stable AC interference caused by AC transmission lines to buried pipelines, high‐speed railways cause dynamic AC interference to nearby buried pipelines. The dynamic fluctuation characteristics of AC interference parameters of buried pipelines

Application of ac Impedance Measurements to Corrosion Monitoring

CORROSION 1983, 1983
Abstract Four different methods for determining the polarization resistance Rpac from impedance data are discussed. These methods are suitable for on-line corrosion monitoring. Their use is illustrated for iron in tapwater and in neutral, aerated Na2SO4 containing various inhibitors.

AC Corrosion and Cathodic Protection of Buried Pipelines

CORROSION 2010, 2010
Abstract The subject of AC corrosion on cathodically protected pipelines, even if already known, arose in the world of corrosion engineers only in the 80ies. Up to that time, only a few countries in Europe where AC traction systems were used were involved and had experience on this subject.

AC Corrosion of Concentric Neutrals: A Case History

CORROSION 1987, 1987
Abstract The corrosion of URD cable direct buried concentric neutral wires has been found on many underground installations across the United States. Corrosion investigators, to date, have clearly proven the prevailing corrosion mechanisms to be of a galvanic or stray DC current nature.
