Flanged pipework can be isolated from corrosive environments by using a flexible, liquid-applied elastomeric material that can be peeled off for inspection and then resealed.
The practical guide was designed to help coatings engineers or specifiers determine candidate protective coating systems for particular industrial environments.
Heavy traffic on the Verrazano-Narrows Bridge meant that the 50-year-old upper level deck required replacement to make way for a lighter-weight orthotropic deck consisting of more durable steel.
Salt spray exposure tests revealed the strength of wax-based coatings in withstanding exposure to sodium chloride (NaCL) as a corrosive agent in truck and trailer manufacturing operations.
Residual soluble salts are contaminants on a substrate surface that affect coating performance. The primary soluble salts that the coatings industry must manage are in the form of chlorides, sulfates, and nitrates.
The effective barrier properties of the graphene nanoplatelets may explain the corrosion mitigation observed on steel panels in both immersion testing and cyclic salt fog testing.
A new polyurethane-based nanocomposite coating system can be applied to steel and concrete without the need for sandblasting, thus reducing application time by half. It can also protect the substrate against fire for two hours without falling off.
Soluble salts left on the surface can cause premature coating failures. As such, all steps and materials used require scrutiny to prevent the potential addition of salts during surface preparation and cleaning.
The 128-year-old dome of the Shah Jahan Mosque near London, United Kingdom was suffering from corrosion-related perforations and leaks. A cold-applied, seamless roof was the solution.
New research at the U.S. Department of Energy’s National Renewable Energy Laboratory is aimed at mitigating corrosion levels in concentrating solar power plants with nickel-based coatings.
Networked sensors open up possibilities for new onboard aircraft features that could immediately alert the flight crew to structural damage as it occurs, like matrix cracking and coating delamination.
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.
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).
