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.

IMPACT Study to Provide Tools for Corrosion Management

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.

Researchers Examine Corrosion of Lead Water Pipes in Aftermath of Flint

Even in the absence of funding for lead corrosion research, a team of scientists at the University of Virginia is pressing forward with a new project aimed at solving problems associated with leaching lead from water pipes.

Results Posted for NACE International’s 2017 Annual Corrosion Career Survey

For corrosion professionals in the United States and United Kingdom, the results of this year’s annual corrosion career and salary survey sponsored by Materials Performance (MP) magazine are very positive.

Thermal Imaging Used for Nondestructive Testing of Concrete Pillars

Russian scientists recently used a thermal imaging technique to study the corrosion of steel reinforcement within 14 reinforced concrete pillars.

Using Pipeline Coatings with Cathodic Protection

During the service life of a pipeline, the coating has to maintain its integrity under operating environments and in the presence of cathodic protection (CP). A coating that exposes bare metal areas renders the pipe surface susceptible to corroding species, and a functional CP system will be required. This article discusses the basic principles of corrosion protection with coatings and CP, and the attributes of an effective pipeline coating.

Steel Bridges Protected with Two-Coat Polyaspartic Urethane Coatings

A second generation of a polyaspartic urethane two-coat coating system with improved wet adhesion and corrosion resistance was developed in recent years for application in warm climates with high humidity.

Study: Graphene Technology Boosts Performance of Epoxy Coatings

Initial test results have shown higher corrosion resistance, increased mechanical strength, and better abrasion resistance when using epoxy resin-based coatings formulated with graphene.

2018 Deadline Nears for New U.S. Underground Storage Tank Rules

The third and final deadline for underground storage tank owners and operators to meet new federal requirements from the U.S. Environmental Protection Agency for spill, overfill, and corrosion protection is October 13, 2018.

Eliminating Coating Failures—A Case Study for Achieving Long-Term Cost Savings in the Oil Field

Giving special attention to surface preparation and eliminating surface contaminants prior to coating can essentially eliminate premature coating failure.

Pitting Repairs for High-Temperature/High-Pressure Process Vessels

The most damaging form of corrosion is localized corrosion, which can be prevented and controlled by using corrosion inhibitors, cathodic protection, and protective coatings.

Advanced Fluoropolymer Fouling-Release Coating

On static structures, such as the steel legs of an offshore oil platform or the hull of an floating production, storage, and offloading (FPSO) vessel, the structural integrity of the welds need to be visually inspected and assessed. If the substrate is covered in biofouling that isn’t easily removed, a large amount of force is required to scrape it off, which may damage the underlying protective coating and leave the substrate vulnerable to corrosion.

Understanding a New Standard

The Canadian Standards Association developed CSA Z245.30-141 for external field-applied coatings on steel pipelines. It defines requirements for the qualification, application, inspection, and testing of external oil and gas pipeline coatings applied in the field or shop.
