Corrosion has long been recognized as an extremely costly naturally occurring phenomenon that can be controlled through the proper application of corrosion prevention and control methods protecting public safety, extending the service life of assets and preventing damage to property and the environment. The landmark Cost of Corrosion Study published by the U.S. Federal Highway Administration estimated that corrosion costs were approximately 3.1% of the nation’s GDP. Within the study, several key sectors of the US economy were studied. This paper is focused on one of those areas – the corrosion risks associated with storage tanks that contain hazardous materials. The study determined that the annual direct cost of corrosion for above ground hazardous material storage tanks (ASTs) in the US was ~$4.5 billion.

NACE SP21427-2019 “Detection and Mitigation of Stray-Current Corrosion of Reinforced and Prestressed Concrete Structures”

Product Number: 21427-SG

Publication Date: 2019

$179.00

HISTORICAL DOCUMENT. This NACE International standard practice establishes the general principles to be adopted to minimize the effects of stray current corrosion caused by direct current (DC) and/or alternating current (AC) from external sources on steel reinforced concrete (RC) and prestressed concrete (PC) structures or structural elements. The standard practice offers guidance for the design of concrete structures that may be subject to stray-current corrosion; the detection of stray current interference; the selection of protection measures; and the selection of mitigation methods.

NACE SP21427-2023, Detection and Mitigation of Stray-Current Corrosion of Reinforced and Prestressed Concrete Structures

Product Number: NACE SP21427-2023

Publication Date: 2023

$109.00

This standard practice describes appropriate prevention and mitigation measures that can be applied to RC and PC structures that are, or can be, exposed to stray-currents from external sources in order to minimize or eliminate stray-current corrosion. This standard practice addresses only steel corrosion related issues, and does not deal with issues of safety and hazards to people or structures associated with DC and AC voltages; these are covered in national standards and regulations, such as EN 50443 and EN 50122-1.
