Utilizing various analytical techniques, this article focuses on a failure investigation of both liquid epoxy and fusion-bonded epoxy coatings for internal applications in sour gas pipelines.
The application of a coating can greatly reduce the amount of current required to obtain cathodic protection. In addition, good coating can significantly improve attenuation characteristics along a pipeline.
The effects of power on the obtained coatings were investigated using a salt spray corrosion test, with results showing that porosity and cracks on the arc-sprayed coatings were significantly eliminated with the increase in power.
The use of vapor corrosion inhibitors in coating formulations has shown that in many systems, they can replace the older technology or significantly improve the performance of the system by working in synergy with the existing inhibitors.
Researchers at the U.S. Department of Energy’s Argonne National Laboratory are working on the development of a new oil-resistant filter technology to prolong the life of equipment in industries such as oil and gas. The new invention consists of a type of coating that produces thin films of oil-repelling molecules on the surface of filter membranes. According to the researchers, the metal oxide molecules grab onto any loose water atoms while resisting oil.
Materials scientists at the U.S. Southwest Research Institute have developed a new superhydrophobic coating and a process for applying it to the internal surface of long tubular structures, which helps prevent offshore drilling pipes from being clogged by various substances.
On Saturday, March 14, NACE International’s Board of Directors voted unanimously in favor of the resolution to bring the combination of NACE and SSPC to a member vote.
The galvanized steel and fireproofing system must perform in unison while in service and, if necessary, during a fire. Factors within the galvanization and surface preparation process influence the system’s ability to perform.
Podcasts from the MP Interview Series explore the impact of COVID-19 on the corrosion control industry.
Scientists are using sacrificial anodes to significantly reduce the acceleration of corrosion in patched concrete areas. The steel is afforded corrosion control thanks to the sacrificial anodes, which are inserted into the patch.
When the plant manager for a Florida oil and gas operating company discovered three holes in a sour crude oil tank, this emergency repair solution allowed the client to avoid total tank replacement.
The tower’s future looked bleak, but it was saved when local residents were successful in rallying for its restoration instead. Now, the colorful and newly coated tower welcomes everyone to the coastal Florida city.
The “Spoonbridge and Cherry” is an iconic sculpture in Minneapolis, Minnesota. Recently, concern was expressed over the condition of the cherry and its coatings. The cherry was inspected, removed, and recoated. This article describes the rehabilitation process and the materials used.
