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.

Innovative Polymeric Solution for Flanged Pipework Protection

Flanged pipework can be isolated from corrosive environments by using a flexible, liquid-applied elastomeric material that can be peeled off for inspection and then resealed.

Evaluation and Repair of a Liquid Sulfur Holding Tank

This case study presents the results of evaluations and repairs made to a sulfur tank at a gas plant in central Alberta, Canada. The repairs exceeded the owner’s expectations for performance and have not required any subsequent concrete repairs of significance.

Medical Device Industry Turns to Plasma-Applied Coatings

To upgrade legacy medical devices under new regulations, the medical device industry is aggressively investigating and applying plasma-applied coatings to products such as stainless steel guide wires, catheters, stents, and vascular surgical tools.

Corrosion Basics: Coating New Construction Seagoing Vessels

Surface preparation and coating application during the new construction of a vessel compose a complex orchestration that requires the coordination of every department in a shipyard. It is also one of the most expensive parts of building a new vessel.

Zinc-rich Epoxy Primer Uses Glass Spheres, Zinc Activator to Enhance Corrosion Resistance

A novel, organic zinc-rich primer coating technology relies on a combination of zinc dust, hollow glass spheres, and a proprietary activator to provide cathodic protection with greatly improved mechanical properties (crack resistance) and adhesion.

Results Posted for NACE International’s 2016 Annual Corrosion Career Survey

Average annual salaries in 2016 are reported for corrosion professionals in the United States, Canada, United Kingdom, and Europe. A slight gain was seen for the United States and United Kingdom, while a larger increase was recorded in Canada.

Advances Made in Epoxy Coating Technology

A single-pack epoxy coating with epoxy-amine reactive functionality was recently developed that delivers reasonable shelf life and a high level of corrosion resistance that is comparable to two-component epoxy polyamide coatings.

What Do You Know about Inorganic Zinc Coatings?

Inorganic zinc silicate coatings, whether solvent- or water-borne, provide a number of unique challenges for the specifier and applicator. This article answers questions relating to selection, application, and maintenance of these coatings.

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.

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.

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.

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.
