A major oil and gas operating company recently revised its engineering standards to include a novel water-borne spray coating system to protect against both atmospheric corrosion and corrosion under insulation (CUI).
U.S. Airmen with the 60th Maintenance Squadron (MXS) at Travis Air Force Base in California, USA are one of two bases currently testing a pair of lasers as a new method of removing paint and corrosion on aerospace ground equipment. They say their traditional method involves the use of an orbital sander or blasting machine.
Experts with a coatings specialist company explain the differences between floor coating systems based on polyurethanes and epoxies, and why the selection often depends on jobsite location. With each system offering differing properties suited to specialized uses, choosing the wrong solution can lead to costly repairs or even complete floor failure down the line.
Fermentation and oxidation processes used by anaerobic digesters in biomass plants can create a perfect recipe for corrosion, both at the gas and liquid phase. Sludge tanks also face similar issues.
The new additive system is comprised of a liquid healing agent encapsulated by a polymeric shell, which upon incorporation into a coating formulation can impart self-healing functionality to the coating. The formulation consists of an epoxy resin, a polar diluent, a corrosion inhibitor, and an adhesion promoter.
The single component, humidity cured, polyurethane/polyurea hybrid nanocoating penetrates into the pores and voids of new or highly oxidized paint systems to form a hard, protective topcoat surface.
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.
In this case study, the contractor was asked to install a new deck coating system to mitigate any potential corrosion and protect against the impact of heavy foot traffic during the peak summer travel season.
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.
