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.

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.

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.

Stray Current Electrolytic Corrosion: An Unrecognized Enemy

SNAME Chesapeake Power Boat Symposium, 2008
This paper examines the state of the art regarding Electrolytic Corrosion which is often mis-named as electrolysis. This corrosion of underwater metals is understood to be caused by stray currents passing through the water surrounding a vessel regardless of source.

Control of Stray Current Corrosion on Reinforced Concrete

CORROSION 1981, 1981
Abstract Extensive underground concrete structures associated with direct current railways are subject to deteriorating effects of stray current. While every effort should be made to effectively insulate the track system so that stray current leakage to structures is minimal, experience indicates that secondary measures for stray current

Corrosion and stray current influence on rails in urban tracks

2021
Corrosion causes a large loss of material from the rail and rail fastening system, which is associated with a reduction in fastening load and can affect traffic safety. The rate of corrosion depends on the type of track and the environmental conditions around the rail.

Aggressive Stray Current Corrosion on an Onshore Pipeline

Materials Performance
Stray current corrosion is an external damage mechanism that might pose a threat to the integrity of buried pipelines. This type of external damage mechanism occurs when currents from nearby anode beds take unintended paths, initiating or accelerating existing external corrosion.
