Corrosion Basics: Locating Pipeline Coating Defects with a Pearson Survey

One of the first successful techniques for locating coating defects (holidays) on buried pipelines using surface electrical measurements is the Pearson survey, named after its inventor.

A Multifunctional Additive for Controlling Inorganic Foulants in Industrial Water Systems

This article presents performance data on polyamino polyether methylene phosphonic acid (PAPEMP) on various mineral scales commonly encountered in boiler, cooling, desalination, geothermal, gas, and oil systems.

Leaking Seawater Tanks Repaired with New, Fast-Curing Material

When a vertical seawater tank sprang a leak at a coastal hydrocarbon storage tank farm in Italy, the tight time window for repair meant that only solutions with very short cure times were an option.

Controlling Cavitation Damage in Pumps on Oil Offshore Platforms

This article explores possible remedies to cavitation, including finishing the surfaces of pump components with a hydrophobic composite coating with a smooth and glassy surface.

Corrosion Basics: ICCP for Atmospherically Exposed Reinforced Concrete Structures

Impressed current anodes for atmospherically exposed steel in concrete are very different from anodes for underground and underwater applications.

Gas Plant Uses Carbon Fiber-Reinforced Polymer Wrap to Strengthen Concrete Columns

Pipe wrapping turned out to be a simple and low-cost method for strengthening concrete columns during the construction of a new natural gas plant in Colorado.

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.

Preventing Releases in Underground Storage Tanks

Underground storage tank (UST) owners and operators must follow correct filling practices and protect their USTs from spills, overfills, and corrosion. Additionally, owners and operators must report the existence of new UST systems, suspected releases, UST system closures, and keep records of operation and maintenance.

Corrosion Basics: Stray Current Effects

Where stray currents discharge from a structure into the electrolyte environment in order to return to the source, corrosion will occur. If the corrosion is concentrated over a limited surface area, the integrity of the structure may be threatened in a relatively short period.

The Science Behind It: Corrosion Caused Lead-Tainted Water in Flint, Michigan

Learn more about the Flint, Michigan drinking water crisis caused by corrosion in this new quarterly special feature, The Science Behind It. Read the MP article to get the basic facts, and then explore the science behind the corrosion problem, which is presented in several related CORROSION articles.

Localized Corrosion Failure of a Hydraulic Pipeline in a Subsea Gas Well

After 10 years of normal operation, a hydraulic circulation pipeline of a subsea gas production well failed at its bend zone due to internal localized corrosion attack. This appears to be related to crevice corrosion and pitting.

Nanocoatings Deliver Performance and Operational Advancements

Carbon nanotechnology advancements and their use in a new coating address the ever-growing demand from asset owners to obtain sustaining and economically viable coating solutions.

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.
