Risk Assessment Justifies Cathodic Protection Retrofit on an Aging Pipeline

As pipelines age, it is important to verify the effectiveness of the coating and cathodic protection systems that protect them against external corrosion, and implement remedial actions if necessary.

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: Open Recirculated Cooling Water Systems

There are certain fundamental considerations that should be understood in relation to open recirculated systems.

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.

Cold-Bonding Polymeric Technique Helps Restore U.K. Trains

A U.K. group specializing in train restoration identified polymeric cold-bonding as a superior solution to welding to help fix recurring problems with metal corrosion in diesel tanks.

University Team Develops Faster Route to Corrosion Detection in Metals

Researchers at the University of Virginia are seeking to modify the traditional cyclic corrosion test chamber by adding ozone to the mix and greatly accelerating the process.

Remote Monitoring System Tracks Cathodic Protection and Sensor Data

There is a need at many remote oil and gas field sites for data typically collected by specialized sensors. To meet this need, a remote CP monitoring platform was developed that combines a dedicated two-channel CP rectifier/test station monitoring device and a dedicated two-channel sensor/transducer monitoring device into one unit.

IMPACT Study Breaks New Ground in Corrosion Management Research and Practice

This article provides a summary of the scope, approach, and significant findings of NACE International’s recent IMPACT study, including corrosion control strategies that could save hundreds of billions of dollars per year.

EPA Finds Moderate or Severe Corrosion in Most Underground Diesel Tanks

In a new report on corrosion inside underground storage tanks storing diesel fuel, the U.S. Environmental Protection Agency found moderate or severe corrosion could affect metal components inside both steel and fiberglass tank systems.

U.S. Study Finds Millions at Risk of High Lead from Corrosive Water

A new U.S. Geological Survey assessment of more than 20,000 wells nationwide showed that untreated groundwater in 25 states and the District of Columbia was classified as potentially corrosive, thus creating a high risk for lead leaching in homes.

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.
