Electroplating fasteners with a Ni-Co alloy can decrease hydrogen production on the coating’s surface and prevent hydrogen penetration into underlying metal.
With the construction of a new digester complex for a Williston, North Dakota, USA wastewater treatment plant, it was imperative that the walls and pipes be properly insulated. Unfortunately, the insulation and pipe wrapping line item was accidentally missed on the bid.
A novel corrosion control prevention kit utilizing shrouded surface preparation tools and demonstration videos is designed to improve the efficiency of in-house maintenance crews for maritime assets. Chris Patenaude, director of maritime and industrial sales at the company and also a NACE International-certified Coating Inspector Program (CIP) Level 3 Inspector, witnessed many common pitfalls firsthand in his prior role as global fleet superintendent for coatings and linings at cruise line operator Royal Caribbean International (Miami, Florida, USA).
The combination of a unique architectural design finished with fluoropolymer coil coatings is geared to provide seacoast corrosion protection for upscale condominiums in Florida. The unique climate concerns to the region prompted an innovative concept from globally renowned architecture company Bjarke Ingels Group (Brooklyn, New York, USA).
Engineering and selecting the most adequate and appropriate pipeline coating depends on a multitude of factors. Careful analysis of several critical factors must be considered, such as the pipe diameter, the service pressures or operating temperatures of the transport materials, the soil conditions if installing a landline, construction techniques for installation, cathodic protection (CP), and whether impressed current CP or sacrificial CP will be used.
A surface-applied corrosion inhibitor, designed to migrate through dense concrete structures and seek out the steel reinforcement bars in concrete, helped stop further corrosion on this iconic Croatian structure.
Researchers have developed an alternative, less expensive anode material for alkaline water electrolysis, which they say promotes less carbon corrosion. The researchers say their new nanostructured catalyst can reduce the rate of carbon-induced corrosion often experienced in alkaline water electrolysis, used to produce hydrogen from renewable resources.
The installation of a weight on the Keystone oil pipeline in South Dakota upon its construction in 2008 appears to have caused mechanical damage to the coating, leading to a recent rupture and oil spill.
The objectives of the study were to develop a protocol for testing protective coating performance on pitted SS, evaluate how various surface preparation methods affect the coating performance on pitted SS, and determine a reliable coating application procedure to cover the pits with a holiday-free film so the integrity of offshore pitted SS is improved.
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.
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.
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.
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.
