A new generation of high-temperature fusion-bonded epoxy coatings are being developed as a lower-cost alternative to alloy steels for protecting the internal surface of tubing, casing, flowlines, and pipelines.
A new system for evaluating coating performance is expected to accelerate the screening, qualification, and implementation of new aircraft coatings.
Silane coupling agent additives were used in mortar in varying proportions, and the effect of the coupling agent content on the mortar’s corrosion cracking resistance and durability properties was studied.
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.
In this case study, the serviceable lifetime of an impeller with an applied WC-Ni brazing layer on the surface measured almost eight times longer than an unbrazed impeller.
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).
To protect against corrosion, the water pipeline was lined internally with cement mortar after applying fusion-bonded epoxy with an abrasion-resistant overcoat.
For specifiers, contractors, and asset owners, it is necessary to make careful, informed decisions about which coatings to use for particular projects.
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.
Embedded technologies can provide monitoring capabilities that capture the onset of tank coating deterioration and follow the evolution of damage.
Because seawater contains a significant concentration of dissolved salts and is very corrosive to steel, infrastructure and assets in or near marine environments are particularly susceptible to corrosion.
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.
