Case Histories

Cathodic Protection for Water Mains in a High-Consequence Transit Corridor

To protect pipelines in a transit corridor where they crossed underneath the light-rail tracks, construction of the line included retrofitting the pipelines with a precast concrete box culvert casing and installing an impressed current cathodic protection (ICCP) system.

Deep Anode Bed in a Flowing Artesian Aquifer

In April 2013, the Las Vegas Valley Water District attempted to install a 500-ft (152-m) deep anode bed for an impressed current cathodic protection system. Before the anodes could be installed, ground water began flowing out of the top of the hole at ~50 gal/min (189 L/m).

Dynamic Pulsed Eddy Current Inline Inspection Technology Assesses Unpiggable Pipelines

To assess internal and external corrosion in piping configurations that are unpiggable or difficult to assess, a novel dynamic pulsed eddy current technology integrated with a robotic inline inspection tool was developed that is capable of internally inspecting metallic pipes.

Eliminating Coating Failures—A Case Study for Achieving Long-Term Cost Savings in the Oil Field

Giving special attention to surface preparation and eliminating surface contaminants prior to coating can essentially eliminate premature coating failure.

Pitting Repairs for High-Temperature/High-Pressure Process Vessels

The most damaging form of corrosion is localized corrosion, which can be prevented and controlled by using corrosion inhibitors, cathodic protection, and protective coatings.

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.

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.

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.

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.

Corrosion ‘Hot Spots’ Found at Central Florida Football Stadium

An engineering study reports significant corrosion, due to poor coating selection and application, that led to structural damage in many locations at a major college football stadium in Florida.

Final Report Issued on Fatal New Zealand Cruise Ship Blast

New Zealand’s Transport Accident Investigation Commission published its final report on a fatal accident involving the massive Emerald Princess cruise vessel, in which a nitrogen cylinder burst and fatally injured a nearby crew member.

Stress Corrosion Cracking Led to Canadian Pipeline Rupture, Fire

Investigators determined that the pipeline ruptured due to stress corrosion cracks on the outside surface, and the polyethylene tape coating applied to the pipe’s exterior surface as an anticorrosion technique had deteriorated over time.
