Chemically Bonded Phosphate Ceramics Provide Corrosion Protection for Storage Tanks

A variety of industrial facilities with structures constructed of carbon steel are at risk of corrosion. An inorganic spray-on protective coating technology provides corrosion protection to metal through a chemically bonded phosphate ceramic.

Encapsulating Technology Protects over 500 Flanges

The repair and maintenance industry has employed many different techniques to combat flange corrosion. A gas supplier decided to commission a flexible and peelable coating system for the protection of over 500 flanges on the site.

Flexible Coatings Help Protect Marine Structures

Corrosion impacts all structures in a marine environment, such as offshore platforms and rigs and ocean-going vessels. One way to minimize and mitigate the effect of some types of corrosion is through the use of flexible surface coatings.

Corrosion Basics: Protecting Fixed Structures in Seawater

Structures such as steel bulkheads, steel piles supporting piers or wharfs, offshore drilling platforms, and other similar structures may be cathodically protected with either sacrificial galvanic anode systems or impressed current systems.

NACE Specific Technology Group Provides Railcar Industry Standards

Specific Technology Group (STG) 43, “Transportation, Land,” promotes the development of techniques to extend the life of land transportation equipment. The committee primarily focuses on writing standards and reports on industry best practices for coating application and corrosion control in and on railcars.

Chromate Primer Alternative Uses Carbon Nanotubes Modified with Corrosion Inhibitors

Scientists have developed a non-chrome primer system by incorporating carbon nanotubes (CNTs) modified with organic corrosion inhibitors into an epoxy-based resin. The goal of the coating development effort was to identify promising CNT-containing non-chrome primer formulations that perform comparably to traditional chromated ones.

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.
