Report: U.S. State Officials Need More Clarity on Bridge Corrosion

Officials from some states told the U.S. Government Accountability Office that they use sealant on bridge decks to prevent corrosion. However, officials from another said they do not, because they do not know how effective it is.

Identifying Pipeline Exposure via River Scour Monitoring Technology

River Scour Monitoring (RSM) systems, through the use of temperature sensing, have proven effective in detecting exposed pipe and the degree of pipeline scour. Identifying scour early on is key because once a pipeline is uncovered, it can be damaged in multiple ways. To avoid pipeline operator liability, and keep people, the environment, and related resources safe, it is important to follow applicable regulations and codes.

Interview: Corrosion Risks to Infrastructure After Wildfire Exposure

Led by Dr. Mehrooz Zamanzadeh, technical director and principal investigator at Matergenics, this roundtable discussion explores the need to conduct corrosion risk assessments of infrastructure after exposure to wildfires.

Laboratory and Field Evaluation of Pipeline FBE Chalking

Correlating predictive laboratory testing with “real-world corrosion conditions” has long been an ambition of the coatings industry. In that spirit, this article addresses the well-known phenomenon of epoxy chalking and examines its effect on fusion-bonded epoxy (FBE) coatings.

How Ultrasonic Sensors Can Enable Permanent Corrosion Monitoring

The Belenus condition sensor utilizes an ultrasonic pulse-echo to provide in-service monitoring of pipe wall thickness. It can be fitted to structures including pipes, storage tanks, and pressure vessels.

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.

Preventing Refinery Corrosion by Process Monitoring, Predictive Analysis

Because refinery operations are so complex, and obtaining accurate asset integrity information has proven to be a challenge, a need exists for quantifying corrosion.

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 Inspection by 3D Non-Contact Profilometry

Corrosion can either take place locally to form a pit or crack, or it can extend uniformly across a wide surface. Proper surface analysis of the corroded sample is vital for evaluating corrosion characteristics and mechanisms, so the best materials, protective coatings, and corrosion-control measures can be selected.

EPA Finds Moderate or Severe Corrosion in Most Underground Diesel Tanks

In a new report on corrosion inside underground storage tanks storing diesel fuel, the U.S. Environmental Protection Agency found moderate or severe corrosion could affect metal components inside both steel and fiberglass tank systems.

Texas Water Utility Partners with University on Corrosion Research

Water utility officials in Arlington, Texas, are working with University of Texas at Arlington researchers to inspect concrete manhole shafts and sewer pipes for corrosion, cracks, and other internal defects.

U.S. Airmen Target Noninvasive Methods to Spot Aircraft Defects

Airmen with the 19th Maintenance Squadron at the Little Rock Air Force Base in Arkansas are using nondestructive inspections to identify potential cracks in a variety of aircraft parts.

U.K. Grant Targets Sensors for Corrosion Protection in Heating, Cooling Units

A collaborative project funded partly by the U.K. government is looking to develop cost-effective sensors capable of measuring the corrosion rates of metals used in water-based heating and cooling units.

Failure of Water Wall Tubes Caused by Hydrogen Embrittlement from Severe Underdeposit Corrosion

In a CORROSION 2017 paper, authors discussed two water wall tubes in a multistage flash distillation plant’s operating boiler that experienced failure after 14 years of service.
