Protecting a Pipeline When Its Coating Has Aged

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.

Stainless Metering Valves Used to Protect Marine Lubrication Systems

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.

PHMSA Eyes Safety Upgrades on Hazardous U.S. Liquid Pipelines

New regulations for hazardous liquid pipelines are part of a series of changes from PHMSA aimed at improving pipeline safety across the United States.

Assessing the Risk of Coating Failure from Residual Soluble Salts

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.

U.S. Army Seeks Biodegradable Bullets to Limit Soil, Water Corrosion

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.

New Safe Containment Project Cuts Corrosion Risk at Chernobyl

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.

U.S. House Panel Concludes State, Federal Failures behind Flint

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.

Proposed Changes to Gas Transmission Pipeline Regulations Intended to Increase Safety

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.

Battling Building Envelope Corrosion

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.

New Technique Tracks Water in Concrete via Electrical Imaging

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.

Key Indicators Can Reveal Signs of Concrete Parking Structure Corrosion

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.

Test Protocol Evaluates Concrete Repair with Sacrificial Anodes

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.

Corrosion-Resistant Thermal Spray Coatings Withstand Supercritical CO2 Environments

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.

Researchers Examine Corrosion of Lead Water Pipes in Aftermath of Flint

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.

Medical Device Industry Turns to Plasma-Applied Coatings

To upgrade legacy medical devices under new regulations, the medical device industry is aggressively investigating and applying plasma-applied coatings to products such as stainless steel guide wires, catheters, stents, and vascular surgical tools.
