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.
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.
The FlexGel range of products are designed to halt the corrosion of carbon steel in subsea flexible and steel risers in the area of an outer sheath/coating damage. The innovation displaces oxygenated seawater from the region of the damage and replaces it with a noncorrosive gel.
Surface-applied corrosion inhibitors, which penetrate the concrete and form a protective film on the steel rebar, have successfully reduced the rebar corrosion rate and extended the service life of many types of reinforced concrete structures.
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.
