Although computational methods have been separately developed to predict corrosion and fatigue crack growth rates for metallic structures, challenges remain in implementing a methodology that considers the combined effects. In this work the output from a galvanic model is used to determine the spatial distribution of corrosion damage; providing a guide for the location of discrete corrosion damage features that can be analyzed using stress fields from structural models. In order to build confidence in this approach the galvanic models are validated by comparing predicted results to surface damage measurements from test specimens subject to ambient atmospheric exposure. There was good comparison between the predicted spatial distribution of corrosion damage and the measured surface damage profiles obtained from the galvanic test specimens. Following this exercise novel computational corrosion damage features were developed to represent simplified cracks shapes emanating from corrosion pits. Stress intensity factors (SIF) for these newly developed hybrid pit-crack features were determined and these solutions compared to cases where the pit is assumed to be an equivalent crack. The impact of the local, cavity induced stress field, on the SIF solutions is discussed. Building on these findings a fatigue crack growth simulation was performed using an initial flaw emanating from a hemispherical cavity (corrosion pit) located at the edge of hole in a plate. A reasonable comparison, of the predicted number of crack growth cycles, to available experimental test results was achieved.

Using Atmospheric Plasma for Enhance Coating Adhesion to Limit the Onset of Corrosion

Product Number: 51323-19191-SG

Protecting and maintaining assets in highly corrosive environments has been a challenge for centuries. Assets that require precision coating removal around compromised structures require a precision tool that does not impact the structure leading to failure. Removal of any metal or damage to surfaces must be avoided in these scenarios, which disqualifies highly abrasive removal methods such as blast cleaning, needle-gunning, and water-jetting.

Using Climate Control at the Job Site; It’s Just Good Business

Product Number: 41207-311-SG

Author: Russ Brown

Publication Date: 2007

$20.00

The use of temporary climate control on a steel tank re-line has now become a regular practice within the coatings industry to help one avoid unplanned delays or issues on a project. This paper will discuss the issue from three perspectives: the coatings contractor, the tank owner and the inspector. It will explore the concept of using a temporary climate control systems on a tank re-line project in general, review how each segment would benefit from utilizing such a system and finally discuss the overall impact that a temporary climate control system will have on their projects.

Using DC Decouplers to Maximize Isolation of Cathodically Protected Structures

Product Number: MECC23-19878-SG

Author: Jay Warner

Publication Date: 2023

$20.00

Cathodic Protection (CP), when properly applied, is an effective technique to minimize the natural corrosion process that occurs on pipelines, tanks, and other buried steel structures. To maintain effective CP coverage with minimal current demand, the structure must be well-isolated from earth for DC current flow. This is commonly accomplished using high resistance coatings, isolation joints, dielectric fittings and isolation pads.

Using Flexible Steel Pipe to Rehabilitate Aging Pipelines

Product Number: 51323-19013-SG

Author: David Gregory, Shawn Poworoznik

Publication Date: 2023

$20.00

This paper highlights a successful rehabilitation of a regulated steel line with flexible steel pipe. The pipeline resides under jurisdiction and was approved by both state and federal pipeline safety administrations. Upon completion, the rehabilitated system restored transmission while also reducing overall operating risk. Use of the flexible steel pipe allowed the operator to utilize a dual-containment design while also implementing real-time continuous annulus monitoring on multiple interfaces, effectively reducing risk to environment and local residents.

Using Forensic Science to Determine Causes of Failures of Polymeric Coatings

Product Number: 41215-875-SG

Author: Jon Asselanis

Publication Date: 2015

$20.00

Often when a polymeric flooring system fails, the cause of the problem is unknown. Forensic testing is used to determine the cause of failure while eliminating other potential causes. A basic understanding of the approach to a forensic investigation and the types of testing used will help aid in correcting the problem so future failures and project costs are reduced.

Corrosion is not just a sustainment concern that impacts the availability and safety of critical structural assets; it is also a damage mechanism that should be considered during the initial design phase. By considering the corrosion process and associated preventive strategies during the design phase it is possible to reduce total ownership cost and improve equipment readiness. The Department of Defense spends more than $23 billion each year to control corrosion on aircraft and other equipment in its operations around the world.
