Corrosion Monitoring and Inhibitors for Production Tubing in Gas Wells

In oil and gas installations, the production tubing is critical in producing fluids from the reservoir. Corrosion of production tubing not only hampers production from the well, but replacement costs are significant, requiring special work-over jobs. Monitoring production tubing to identify corrosion problems and using inhibitors to extend service life is discussed.

Corrosion Basics: Steam Generation in Power Plants

The greatest use of high-temperature water and steam is in electrical power generation. Historically, fossil fuels were used almost exclusively to heat water for steam until the introduction of nuclear power steam generators. This article briefly summarizes corrosion considerations for fossil fuel and nuclear fuel steam plants.

NACE, SSPC Publish Joint Wet Abrasive Blast Standards

NACE International recently published five new joint companion wet abrasive blast (WAB) standards with the SSPC: The Society for Protective Coatings. These standards define the processes for preparing a carbon steel surface to a specified degree of surface cleanliness using a WAB cleaning method.

Fundamentals of Rectifier Operation, Monitoring, and Maintenance

Cathodic protection (CP) is an important component for the sustainability of many metal structures. The most common impressed current voltage sources are rectifiers, which can break down. Well-maintained rectifiers can provide uninterrupted CP, which reduces repair costs and labor/technician time.

Correcting Concrete Corrosion

Corrosion of the reinforcing steel in concrete is a worldwide problem that causes a range of economic, aesthetic, and utilization issues. However, if corrosion effects are considered in the design phase and the right decisions are made prior to construction, buildings can be constructed to resist corrosion.

Corrosion Basics: Close-Interval Potential Surveys

The principle of a close-interval potential survey is to record the pipe-to-soil potential profile of a pipeline over its entire length by measuring potentials at intervals that do not significantly exceed the depth of the pipe.

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.

Century-Old Stormwater Tunnel Rehabilitated with Spray Lining

When a 200-ft (61-m) stretch of an arch tunnel on a stormwater collection line in the old town section of Guangzhou, China suffered severe damage to the brick-and-masonry structure due to root intrusion and corrosion, a spray-applied lining was used for rehabilitation.

Corrosion Basics: Tank and Containment Linings

Some of the most critical uses of protective coatings involve service conditions that require the use of coatings as linings. They may be the same coatings that are used in atmospheric or underground service, but they are usually specially formulated for three specific purposes.

IMPACT Study Benchmarks Corrosion Management Practices Across Industries

NACE International has embarked on a study—IMPACT—that goes beyond the economic effects of corrosion; it emphasizes how to integrate corrosion technology with organizational management systems to optimize corrosion decisions with respect to both cost savings and concern for safety and the environment.

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.

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.

Continuous Remote Corrosion Monitoring Supports Environmental Compliance for Jetty Operations

Ships and barges need a certain amount of water depth to safely load and unload product, so most facilities use jetties to enable vessels to moor in deeper water. The use of carbon steel, however, opens up the risk of internal corrosion.
