Improved Packaging Film with Vapor Phase Inhibitors, High Recycle Content

Plastic packaging films can be readily impregnated with vapor-phase corrosion inhibitors (VCIs) to provide corrosion protection, in addition to the basic physical barrier afforded by the plastic.

Corrosion of Preheater Tubes in a Heat Recovery Boiler

External corrosion of preheater tubes in a power plant heat recovery boiler was analyzed, revealing that the preheater tubes were attacked by the sulfuric acid-containing electrolyte from the sulfur-containing environment.

Researchers Launch New Corrosion Studies on Solar Cells

Researchers from industry, academia, and U.S. Department of Energy laboratories are working together to research the corrosion of solar cells, with a goal of developing longer-lasting photovoltaic panels.

Researchers Test Materials in Tropics to Better Preserve Military Equipment

The Department of Defense Corrosion Policy and Oversight Office enlisted partners to expose various materials to outdoor tropical regions.

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.

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.

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.

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.

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.

Long-Term Field Performance of an Organic Corrosion Inhibitor for Reinforced Concrete

Reinforced concrete samples with an organic corrosion-inhibiting admixture were exposed in a road salt environment in the Swiss Alps and periodically inspected over 18 years using a number of test methods.

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.

New U.K. Collaborative Research Project Targets Oil, Gas Corrosion

Researchers from BP and several prominent European universities were awarded a contract to investigate the processes that cause surface degradation and develop new mitigation strategies.

Researchers Eye Advanced Sensors to Monitor Buried Infrastructure

Novel advanced sensors were attached to a hazard-resilient plastic pipeline installed underground and tested through a simulated fault rupture.

New Tantalum Alloy Resists Highly Corrosive Environments

The results of recently completed trials show that adding low levels of ruthenium improve the corrosion and hydrogen enrichment resistance of a tantalum alloy in both hydrochloric and sulfuric acids at high temperatures.

Self-Consolidating Concrete Shows Promise in Bridge Repairs

A Virginia Department of Transportation investigation studied the use of self-consolidating concrete with and without galvanic anodes to repair substructure elements with vertical and overhead sections.
