Corrosion Basics: Stress Corrosion Cracking

Stress corrosion cracking (SCC) is a mechanical-chemical process leading to the cracking of certain alloys at stresses below their tensile strength.

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.

Strategic Planning at NACE International

Strategic planning is a process that provides a roadmap for taking our association from a well-defined present state, to a compelling and significantly different future state.

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.

Corrosion Basics: High-Temperature Corrosion

High-temperature corrosion does not require the presence of a liquid electrolyte. In this corrosion mechanism, metals react directly with gaseous atoms in the atmosphere rather than ions in solution. Sometimes, this type of damage is called “dry corrosion” or “scaling.”

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.

Applying Cathodic Prevention to Electric Transmission Tower Foundations

A novel approach is presented regarding corrosion assessment and cathodic prevention of foundations for electric transmission towers in the Persian Gulf region.

Steel Bridges Protected with Two-Coat Polyaspartic Urethane Coatings

A second generation of a polyaspartic urethane two-coat coating system with improved wet adhesion and corrosion resistance was developed in recent years for application in warm climates with high humidity.

Corrosion Basics: Coating Concrete

Before a concrete structure can be coated, it is necessary to understand and overcome concrete's natural properties.

Teaching Cathodic Protection with an Outdoor Pipeline Integrity Lab

A major U.S. university is using funding from Phillips 66 to develop a new outdoor pipeline integrity lab, which will include buried pipe with an active rectifier to simulate real-life activities.

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.

Polyurea Coatings Protect Aging Concrete Wastewater Infrastructure

Advanced polyurea coatings and liners can provide strong, flexible waterproofing to bridge cracks and protect against future cracking and deterioration.
