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.
The country’s existing pipeline infrastructure was built with materials that are no longer used today, although they were state-of-the-art at the time. Coating materials, for example, have significantly improved over those used decades ago.
The protection of automatic marine lubrication systems with stainless steel (SS) metering valves could offer significant advantages over a prior solution of encapsulating valves in epoxy.
New regulations for hazardous liquid pipelines are part of a series of changes from PHMSA aimed at improving pipeline safety across the United States.
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 U.S. Army wants to use biodegradable ammunition during training exercises, due in large part to how existing bullets can corrode and pollute the soil and water.
The new containment structure, moved into position in November 2016, includes a ventilation system that developers say will help ensure there is no need to replace the coating used to control corrosion.
The U.S. congressional committee investigating the water crisis in Flint, Michigan issued final letters citing failures at all levels of government, including problems at both the Michigan Department of Environmental Quality and the U.S. Environmental Protection Agency.
A notice of proposed rulemaking issued by the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety outlines significant changes to the Pipeline Safety Regulations that are intended to increase the safety of natural gas pipelines.
Efficiently managing the effects of concrete corrosion can extend the life of a building; however, concrete is not the only component threatened by corrosion. On any building, both the cladding and fasteners holding it in place are exposed to varying degrees of corrosion.
Researchers at North Carolina State University and the University of Eastern Finland are working on a novel technique for tracking water in concrete through the use of electricity.
Experienced concrete maintenance and restoration specialists explain the unique challenges in protecting parking structures from a constant onslaught of environmental stressors and wear and tear, along with examples of successful repair techniques.
One of the most common drivers of concrete repairs is corrosion of the concrete’s steel reinforcement, often caused by chloride ions in the environment entering the concrete and eventually reaching the embedded steel.
Researchers have concluded that HVOF-sprayed coatings comprised of UNS R50250, UNS N10276, UNS N06625, and UNS S31603 can provide a cost-effective corrosion mitigation method for infrastructure likely to be in contact with a mixture of wet supercritical CO2 and H2S.
Even in the absence of funding for lead corrosion research, a team of scientists at the University of Virginia is pressing forward with a new project aimed at solving problems associated with leaching lead from water pipes.
