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.
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.
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.
NACE International’s International Measures of Prevention, Application, and Economics of Corrosion (IMPACT) study is nearing completion and will be released in March 2016. A segment of the report focuses on the Corrosion Management System Framework and how a company can incorporate one into its own program.
Experienced concrete maintenance and restoration specialists explain the unique challenges in protecting parking structures from a constant onslaught of environmental stressors and wear and tear, along with examples of successful repair techniques.
Unmanned aerial vehicles (UAVs), are being utilized more and more in various industries to safely and efficiently inspect critical assets and infrastructure that would otherwise be difficult to access.
A combined-cycle power plant in Asia utilizes seawater as auxiliary cooling water (ACW). The carbon steel ACW pipe was lined with coal tar epoxy. After six months in operation, the ACW pipe started leaking due to internal corrosion. A retrofit impressed current cathodic protection (ICCP) system was installed.
There is a need at many remote oil and gas field sites for data typically collected by specialized sensors. To meet this need, a remote CP monitoring platform was developed that combines a dedicated two-channel CP rectifier/test station monitoring device and a dedicated two-channel sensor/transducer monitoring device into one unit.
