Cathodic Protection

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.

U.S. Navy Utilizing Remotely Operated Vehicles to Check for Corrosion

The ROVs measure metal thickness, paint thickness, and cathodic protection (CP) voltage—a corrosion prevention technique the Navy uses that charges the hull at a certain voltage to slow down corrosion.

Nomination Period Opens for 2021 MP Corrosion Innovation Awards

The nominating period is now open for next year’s Corrosion Innovation of the Year Awards, with winners recognized in a wide range of categories related to corrosion prevention and mitigation.

Applying Over-the-Line Potential Surveys in Water/Wastewater Pipelines

Researchers performed two case studies to determine if over-the-line potential surveys could be successfully applied to electrically discontinuous water/wastewater lines and if the results aligned with the direct assessment methods.

Corrosion Basics: Locating Pipeline Coating Defects with a Pearson Survey

One of the first successful techniques for locating coating defects (holidays) on buried pipelines using surface electrical measurements is the Pearson survey, named after its inventor.

NACE International’s Annual Corrosion Career Survey Results for 2015

Corrosion professionals in North America and Europe have experienced another year of continued growth in career opportunities and salary levels, according to the 2015 Corrosion Career Survey conducted by Materials Performance magazine.

Wanted: Technical Articles for MP

To successfully communicate the wide variety of corrosion-related issues affecting corrosion professionals today, MP is actively encouraging corrosion control professionals worldwide to submit technical articles to share their corrosion-related experiences with over 36,000 NACE International members around the globe.

Corrosion Effects on the Durability of Reinforced Concrete Structures

Several myths concerning the cause of reinforced concrete deterioration prevailed in the mid-20th century, but steel corrosion is by far the biggest durability issue for reinforced concrete structures.

NACE Technical Committees—Volunteering Has Its Rewards

Want to know how you can become more active in NACE? There are many opportunities for NACE members to volunteer, and the technical committees offer many benefits such as having an impact on industry standards, developing a network of peers, and enhancing your career.

Lack of Basic Corrosion Control Results in Catastrophes

Safety, function, and service life should be a part of every project. To address these parameters, consideration must be given to design, choice of materials, construction methods, active and passive surface protection, and other parameters.
