Cathodic Protection

Effects of Simulated Marine Environments on Steel in Cracked Concrete

The scientists emphasize that improving the quality of concrete used in creating marine structures can be accomplished by making it less permeable and increasing the clear cover. When these steps are taken, the time to corrosion is much longer.

Best Available Design Technologies for Pipeline Isolation

There are many offerings for both above- and below-ground pipeline isolation. But only certain designs may be appropriate, considering the varied applications that pipelines have, changing conditions, and the need to design for a sustainable future.

CP Known Unknowns: The Impact of Stray Current, Tellurics

This webcast explores some of the common ”known unknowns” that can materially impact cathodic protection (CP) system performance, from both overall efficacy and regulatory reporting points of view, along with best practices to manage them.

Working Smarter, Not Harder with Remote Corrosion Monitoring

The availability of data via remote ultrasonic monitoring tools means greater productivity. Not only can employees monitor corrosion-rate data in almost real-time, but they can overlay this information with operational data.

Al-Zn-In Galvanic Anodes—Specifications vs. Manufacturing Process

Some observations about the particularity of specifying the type of furnace for the fabrication of Al-Zn-In galvanic anodes have been recently published. However, a review of existing standards indicates that none specify the manufacturing process.

New Remote Monitoring Unit is a Global Game-Changer

The objective of the system are to revolutionize the U.S. remote monitoring industry by addressing many existing shortcomings and creating a new standard of cathodic protection RMU, which can deliver superior data more frequently and at a lower cost.

Webcast: Optimizing Cathodic Protection in Urban Utility Environments

This webcast explores how downstream gas distribution and water utilities are setting out on a journey to optimize their cathodic protection (CP) assets in high-consequence areas (HCAs) due to proximity to residential areas.

A Water Department’s Proactive Approach to Infrastructure and Reliability

When the failure occurred, Tucson Water employees were in a hurry to figure out what their next steps would be. This article details the failure, the remedial actions, and the proactive approach they've taken since.

Podcast: How New Technologies are Boosting Cathodic Protection

Tony da Costa, vice president of engineering at MOBILTEX, explains how new technologies are allowing field technicians to improve their remote monitoring and interruption programs.

Direct Electrical Heating Impact on Subsea Pipeline Integrity

Hydrates can be prevented by using subsea pipeline electrical heating technology. Direct electrical heating controls the temperature on the pipeline and offers the potential to significantly reduce operating costs.

MP Announces Winners of 2021 Corrosion Innovation Awards

Materials Performance (MP) magazine is proud to introduce a new class of winners from the 2021 MP Corrosion Innovation of the Year Awards program.

The Current State of Lightning Immunity in Pipelines

While lightning itself does not cause corrosion, the damage it creates to a pipe's walls, coatings, and cathodic protection system can leave a pipeline vulnerable.

Association for Materials Protection and Performance (AMPP) Is Formed

Having launched on January 6, 2021, the new organization, Association for Materials Protection and Performance (AMPP), represents a combination of NACE International and SSPC: The Society for Protective Coatings.

Evaluation of Florida Bridge Pilings

Many bridges in coastal areas are supported by precast pilings that are either continuously or periodically exposed to harsh saltwater conditions, requiring cathodic protection. These researchers studied two decommissioned pilings from the Veterans Memorial Bridge in Florida.

PHMSA Plans to Modernize U.S. Gas Pipeline Safety Rules

PHMSA is proposing to clarify that cathodic protection rectifiers can be monitored remotely and to revise the requirements for assessing atmospheric corrosion on distribution service pipelines.
