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.
Giving special attention to surface preparation and eliminating surface contaminants prior to coating can essentially eliminate premature coating failure.
The most damaging form of corrosion is localized corrosion, which can be prevented and controlled by using corrosion inhibitors, cathodic protection, and protective coatings.
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.
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.
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.
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.
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.
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.
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.
