Stray Current Corrosion of Water Distribution Piping

CORROSION 1990, 1990
Abstract This paper discusses a case history where stray current activity from a DC operated streetcar system caused extensive corrosion leaks in a new metallic water distribution system within a short time. The water system is located in a suburban Philadelphia community. Investigations which determined the cause of the premature leaks,

Cathodic protection, corrosion and stray current corrosion of lead

Anti-Corrosion Manual, 1969
Cathodic protection by galvanic or impressed current techniques is probably the most favoured method of obviating the corrosion of buried and immersed metals. The theoretical principles and the economics involved in such protection are well established now and have been the subject of numerous papers, monographs and reviews.

Stray Current Corrosion Assessment of Utility Pipes

2016 Joint Rail Conference, 2016
Stray current corrosion will occur at each point where the current transfers from a metallic conductor (such as structural reinforcement) to the electrolyte (i.e, the soil or concrete). Hence stray current leakage can cause corrosion damage to the rails, railway metallic structures, utility pipelines in the soil and any other low resistance metal ...

Analysis of Stray Current Corrosion on Buried Pipeline due to HVDC Grounding Current

2020 IEEE 29th International Symposium on Industrial Electronics (ISIE), 2020
The electrochemical corrosion of buried pipeline underground due to stray current has become a typical industrial problem. The stray current causes anodic electrochemical corrosion at defect area on the surface of buried pipeline. In this paper, the DC stray current, which was originally returning current from grounding electrodes of HVDC monopolar ...

Aggressive Stray Current Corrosion on an Onshore Crude Line

CONFERENCE 2023, 2023
Abstract Stray current corrosion is an external damage mechanism that might pose a threat to integrity of buried pipelines. This type of external damage mechanism typically occurs when a current from nearby cathodic anode bed takes an unintended path and either initiates or accelerates existing external corrosion processes. The objective

Control of Stray Current Corrosion by Application of Corrosion Inhibitor

CONFERENCE 2025
Abstract In oil and gas production operations, multiple sources of voltages and currents are prevalent due to the necessity of various motors, pumps, and cathodic protection systems. Unintended current flow can occur through undesired paths caused by grounding issues or failed electrical insulation, leading to severe corrosion that ...

Monitoring DC Stray Current Corrosion at Sheet Pile Structures

2011
Steel is discarded by railway owners as a material for underground structures near railway lines, due to uncertainty over increased corrosion by DC stray currents stemming from the traction power system. This paper presents a large scale field test in which stray currents interference of a sheet pile wall was monitored in realistic conditions.

Protection of underground installations from corrosion by stray currents

Metal Science and Heat Treatment of Metals, 1960
In the great majority of cases, the danger of corrosion for underground installations {water, steam, gas piping, etc.} is caused by direct current escaping from the main d. c. network. Such main networks are the systems of city streetcars and electrified railroads as well as grounded electrical distribution points and industrial power plants.

Stray‐Current Corrosion of Underground Distribution Systems

Journal AWWA, 1957
THE corrosion of metals, particularly as the formation of rust when iron and steel are exposed to the action of the elements, is familiar to everyone. It is known that such exposed metal surfaces must be periodically painted, coated, or otherwise protected to prevent this rusting action.

Galvanic, Deposition, and Stray-Current Corrosion

1999
Abstract This chapter discusses three related corrosion mechanisms, galvanic, deposition, and stray-current corrosion, explaining why they occur and how they affect the corrosion process. It includes information on testing and prevention methods along with examples of the type of damage associated with these corrosion mechanisms.
