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