Leak Mitigation of Dynamic Cracks in Concrete

Product Number: 41216-982-SG

Author: Charlie Lerman

Publication Date: 2016

$20.00

Concrete will crack – that is a fact. When cracks appear, they are dynamic or static, and structural or non-structural. If the crack is static, non-structural, and does not leak, epoxies are great to restore design strength. However, since concrete constantly shrinks, expands, and often leaks, the use of a flexible polyurethane resin to permanently seal active leaks is the optimum choice to create a leak-free environment.

Learning from Failure: The Key to Advancements in Metallurgy and Corrosion

Product Number: 51324-21152-SG

Author: Anil Kumar Chikkam; Aaron Ulmer; Edward Larkin; Mehrooz Zamanzadeh

Publication Date: 2024

$40.00

In the field of metallurgy and corrosion, it is of paramount importance to acknowledge that no failure should ever be underestimated or dismissed as trivial. Each failure carries its own unique narrative and offers invaluable insights into the underlying causes and potential risks. This paper emphasizes the utmost significance of understanding and analyzing metallurgical failures, irrespective of their perceived severity. By meticulously examining every failure as an individual case, substantial lessons can be derived, leading to advancements in designs, materials, and manufacturing processes. Through meticulous investigations and the application of failure analysis techniques, the intricate stories concealed within each failure can be unraveled. These comprehensive analyses provide crucial information for identifying root causes and establishing preventive measures. The paper presents compelling case studies that exemplify the consequences arising from insufficient knowledge on material selection, neglecting stress raisers, mishandling of materials, and the absence of robust inspection plans. These failures range from production losses to fatal incidents, underscoring the criticality of learning from past experiences and implementing proactive measures to avert such occurrences.

Learning to Specify Vinyl Ester Linings for FGD Applications

Product Number: 41208-456-SG

Author: Jeffrey Stewart

Publication Date: 2008

$20.00

Vinyl Ester based lining systems are a proven commodity as a corrosion control technology in Flue Gas Desulfurization (FGD) Systems . The problem is they have proven to be alternatively successful or unsuccessful. The “how to” of receiving a good system is in learning the way a lining system works and the correct methods of application, so that a proper specification can be prepared.

Lessons Learned for Painting Over Hot-Dip Galvanizing

Product Number: 51217-048-SG

Author: Kevin Irving

Publication Date: 2017

$20.00

This paper provides an introduction to the hot-dip galvanization process as an effective and important coating option and the necessary surface preparation steps for successful painting over hot-drip galvanized steel, also known as a duplex system. Proper practices and procedures must be used to prepare new and weathered zinc-coated surfaces on after-fabrication steel products for painting to improve the bond of paint to the zinc surface and provide long-term protection against corrosion.

Lessons Learned from Dehumidification Specifications, Good and Bad

Product Number: 51219-215-SG

Author: Don J. Schnell

Publication Date: 2019

$20.00

There have been specifications written for the use of dehumidification during surface preparation and coatings since the early nineties. These early specs keyed in on parameters that were believed to get the job done and reflected the limited knowledge and experience of a very new industry. Since then, dehumidification has become much more widely accepted and specifications exist for pipes, above ground storage tanks, ships and containments.

Leveraging Geospatial Corrosion Data to Facilitate Smart Decision-Making in Municipal Water and Wastewater Infrastructure Management

Product Number: 51324-20370-SG

Author: Wenxuan Dong

Publication Date: 2024

$40.00

Municipal water and wastewater infrastructure face persistent corrosion challenges, leading to pipeline failures and asset degradation. This paper introduces a comprehensive approach for smart decision-making, integrating geospatially-referenced corrosion data, including soil resistivity, stray current, and pipe break history. The experimental work involves data collection and analysis from various municipalities, resulting in a visual representation of corrosion risk. Case studies demonstrate the approach's effectiveness in optimizing resource allocation and corrosion control strategies. Expected conclusions highlight improved infrastructure performance, cost-efficiency, and sustainability.

Leveraging Physical and Virtual On-Aircraft Sensors to Inform Maintenance Practices

Product Number: 51324-20921-SG

Author: Rebecca Skelton Marshall; Dan Christy; Floyd Steele; Fritz Friedersdorf; Sam Kunselman

Publication Date: 2024

$40.00

Time-based inspection and maintenance intervals are a conventional method of corrosion monitoring on aircraft. However, as corrosion processes do not necessarily occur in scheduled events, these conventional maintenance practices can lead to over- or under-estimation of costly inspections. A shift toward evidence-based and data driven predictive maintenance using a combination of on-asset monitoring devices and component-level models could improve efficiency and reduce total ownership costs. In particular, a “virtual sensor”, i.e., a trained model to predict the corrosion at a given location on the aircraft, can be leveraged to optimize the placement of physical real-time monitoring devices. This digital twin process can be applied to determine the corrosion susceptibility of a single aircraft, or to conduct a fleet-wide analysis. In this work, sensing device measurements deployed at varying locations will be used to demonstrate the applicability of severity tracking, through data-driven machine learning models. In particular, models will be trained on environmental parameters and leveraged to predict current (corrosion rate).

Leveraging Risk Insights For Aging Management At Nuclear Power Plants

Product Number: ED22-17189-SG

Author: Emma Wong, Andrew Mantey, Fernando Ferrante, Jessica Brock, Andrew Burgess, Barry Thurston

Publication Date: 2022

$20.00

Many utilities around the world are pursuing long-term operation (LTO) of their nuclear power plants beyond the initial licensing period. In the United States, the majority of the renewed licenses have allowed the period of operation to be for up to 60 years and a few renewed licenses of up to 80 years of operation, with comparable efforts worldwide. Aging Management Programs (AMPs) are a key element in long-term operation of nuclear power plant and require effective implementation to ensure long-term safety and reliability of vital systems, structures, and components (SSCs). Typically, aging management implementation strategies have been focused on near-term obligations, and these may not be optimal for accomplishing longer-term reliability and sustainability objectives. Therefore, to optimally manage the potential impacts of aging, risk insights can be leveraged using a consistent and sustainable Framework that would focus on high-value actions while reinvesting knowledge and resources. This would allow the implementation of AMPs to enhance and optimize inspection, repair, and mitigation activities.

Life Beyond 80: Can Concrete Degradation’ Synergetic Modes Become Showstoppers for Light Water Reactors?

Product Number: ED22-17261-SG

Author: Yann Le Pape, Elena Tajuelo Rodriguez, Bethel Amani Cheniour, Mohammed Alnaggar, Paula Bran Anleu, Thomas M. Rosseel, David Arregui Mena, Adam Brooks

Publication Date: 2022

$20.00

The US light water reactor (LWR) fleet is a strategic US asset for meeting the demand for clean, sustained, and affordable energy. Extended operations are governed by endogenous (e.g., aging management, operation costs) and exogenous (e.g., natural gas, deployment of advanced nuclear reactors) economic factors but also by technical issues associated with doubling the original 40 year license period. Materials aging includes all critical components of the reactors, such as internals, reactor pressure vessel, cabling, and concrete structures.
