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.

Study: Lack of Corrosion Controls Caused Flint Water Crisis

Led by university researchers, the findings of this new study support the understanding that lead leached into the pipes system in Flint, Michigan, because the water wasn’t treated to prevent corrosion.

Study Evaluates Chloride Limits for Structural Reinforced Concrete

Research on chloride limits for reinforced concrete found a relationship between the initial calculated total chloride content and the measured water-soluble chloride content in hardened concrete.

Device Measures Nanoscale Crevice, Pitting Corrosion in Real Time

University researchers developed a device called a surface forces apparatus (SFA) to get a real-time look at the process of crevice and pitting corrosion on confined metallic surfaces.

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.

X-Ray Analysis Used to Predict Sulfur Corrosion Rates in Crude Oil

Industry and university researchers are using x-ray techniques to develop an analysis tool to more accurately predict how sulfur compounds in crude oil could corrode processing plant equipment.

Fungi Species Could Limit Concrete Corrosion by Healing Cracks

Researchers say the application of a specific species of fungi into the concrete matrix during the mixing process could serve as an unusual candidate to help concrete heal itself.
