02265 CARBON PAINT ANODE FOR REINFORCED CONCRETE BRIDGES IN COASTAL ENVIRONMENTS

Product Number: 51300-02265-SG

ISBN: 02265 2002 CP

Author: S. D. Cramer, S. J. Bullard, B. S. Covino, Jr., G. R. Holcomb, J. H. Russell, C. B. Cryer and H. M.

Publication Date: 2002

$20.00

Solvent-based acrylic carbon paint anodes were installed on the north approach spans of the Yaquina Bay Bridge (Newport OR) in 1985 and performed well after 15 years. Anodes were inexpensive and repairs easy. Depolarization potentials are consistently above 100 with long-term current densities around 2 mA/m 2. Bond strength remains adequate.

Advanced Corrosion Assessment Techniques Used to Prioritize Maintenance of NASA Wind Tunnels

Product Number: 51219-185-SG

Author: Robert A. Ernsting, Adam Beers, David E. Shinn, Thomas E. Hegland, Peter M. Pachlhofer

Publication Date: 2019

$20.00

This paper discusses an innovative technique employed on the 2017 AETC Corrosion Control Study conducted on 19 NASA wind tunnel facilities located at three NASA Centers: Langley, Ames and Glenn Research Centers. The technique adds structural and prioritization context to corrosion and coating assessments which yields an Overall Risk Priority (ORP) score for each inspection item.

Assessing Coating Breakdown Factors of Silicone Rubber Thermal Insulation for Enhanced Cathodic Protection in Subsea Equipment Operations

Product Number: 51324-20350-SG

Author: Herman E Amaya; Behrang Fahimi; John Bogard

Publication Date: 2024

$40.00

This study seeks to redefine coating breakdown factors for thermal insulation coatings, whose unique electrical insulation properties have been previously overlooked in DNV RP B401, resulting in potential miscalculations in anode requirements for cathodic protection systems.1 By comparing the insulation's performance with standards like DNV RP B401 and ISO 15589-2, and through testing and analysis, this study presents refined breakdown factors and insights into optimized anode placement in subsea structures like trees and manifolds.

Coating Performance Over Partially Blasted Surfaces

Product Number: 51219-180-SG

Author: Patrick Cassidy, Peter Ault, Cameron Miller , Colton Spicer

Publication Date: 2019

$20.00

Common methods of maintenance painting either involve complete removal of existing paint (SSPC-SP 10) or localized preparation using power tools (SSPC-SP 3). Sometimes an intermediate level of surface preparation may be performed by allowing intact tightly adherent coating to remain. Abrasive blasting may be used to prepare either localized areas, or to partially prepare the entire surface, allowing well-adhered aged coating to remain.

Considering Over Coating? Details to Examine

Product Number: 51219-216-SG

Author: Bill Seavy, Tim Davis

Publication Date: 2019

$20.00

There are many factors which need to be considered when making the decision to over coat an existing coating system. With the magnitude of data that need to be evaluated in relation to the existing coating system and potential scenarios that are possible it is important to take multiple details into account. Details including inspection criteria of the existing coating system and substrate, owner’s goals and objectives, asset location and environmental conditions must all be taken into consideration.

Electrochemical Impedance Spectroscopy (EIS) Analysis of Freshwater Foul-Release Coatings

Product Number: 41213-789-SG

Author: Bobbi Jo Merten, Allen Skaja, David Tordonato

Publication Date: 2013

$20.00

Foul-release coating systems were examined by electrochemical impedance spectroscopy (EIS) to measure the degradation of coating dielectric properties in immersion. Three-inch by six-inch coated steel coupons were placed in dilute Harrison’s solution (DHS) to simulate constant immersion field conditions.

Fluoro-Urethanes Coatings with Extreme Exterior Durability

Product Number: 41207-314-SG

Author: Liza Capino

Publication Date: 2007

$20.00

Performance properties of solvent-based urethane topcoats formulated with fluorinated polymers are reviewed. Fluoro-urethanes offer outstanding gloss and color retention, good chemical resistance, and excellent adhesion. The long coating service life of fluoro-urethanes reduces the frequency of maintenance work and subsequent downtime interruption.

Methodology for Coated Infrastructure Inspection by Mobile Potentiostat

Product Number: 41215-912-SG

Author: Bobbi Jo Merten, Susan Drozdz, Cassidy Gills, David Tordonato, Jeff Ryan

Publication Date: 2015

$20.00

A test methodology is shown for field application of electrochemical impedance spectroscopy (EIS). The method utilizes low-cost, accessible materials to secure a temporary solution cell to the infrastructure’s coated surface. A laptop computer provides the power source and operating system for the mobile potentiostat during EIS data collection. This data provides a quantitative measure of the coating condition. The objective of this work is to incorporate EIS testing into standard coatings inspection to estimate remaining service life for the intact coating, which improves coatings maintenance planning for facility owners.
