Estimating Corrosion of Embedded Steel Rebars in Bridge Structures

Based on empirical and theoretical research validated by field data, Minnesota Department of Transportation (MnDOT) researchers developed a guidance tool to predict rebar reinforcement section loss. This should help MnDOT manage its bridge inventory and inform bridge maintenance and replacement decisions.

Thermal Insulation Solution Protects Oil Dispersant Vessel

New polymer technology from Belzona is allowing a client to protect its vessel against extreme operational conditions, all while also meeting weight and thickness specifications. The solution proved more effective than traditional cladding.

Final Report Issued on 2019 Refinery Fire, Explosion in Philadelphia

The U.S. Chemical Safety and Hazard Investigation Board released its findings regarding a massive fire and explosions at the Philadelphia Energy Solutions refinery in 2019. The incident occurred when a corroded pipe elbow ruptured, releasing process fluid into the hydrofluoric acid alkylation unit.

Hydrochloric Acid Corrosion of a Venturi Gas Scrubber

A common source of gaseous compounds in the refining industry is the overhead exhaust/vent of the regeneration tower within a continuous catalytic reforming unit.

Transducers Use Ultrasonic Guided Waves to Detect Pipe Anomalies

The San Antonio-based Southwest Research Institute is creating its next generation of transducers using ultrasonic guided wave technology to help detect anomalies in pipes. In turn, this is designed to allow users to prevent leaks before they start.

Comparing Corrosion Among Three Coastal Florida Sites

Knowing the corrosion severity of a particular environment is important when designing and maintaining infrastructure—and even more so in coastal environments. Certain factors can cause corrosion rates to vary significantly. This study aims to provide answers.

U.K. Rail Regulator Publishes Trains Safety Report

The Office of Rail and Road, the economic and safety regulator of Britain’s railway, made a series of recommendations based on a review of how the rail industry responded to a range of potential safety issues, including cracking.

Study: How Rising Sea Levels Affect Foundations

A new study by Colorado State University civil engineers examines hidden costs to building foundations due to rising sea levels. They propose a method for inspection and repair to lower costs associated with deterioration from saltwater corrosion.

Current Mapping Assists in Evaluating Pipelines: How Pipeline Mapping Works

Pipeline current mapping methodology, which has been extensively utilized and designed through a collaboration among several gas companies, involves evaluating the coating of a pipeline from above ground. This is accomplished via the use of electromagnetic techniques.

Deadline Nears for 2023 MP Corrosion Innovation Awards

Winning innovations must show potential for a positive impact in corrosion control. Innovations can be related to coatings and linings, materials, design, equipment, testing, monitoring, modeling/risk assessment, cathodic protection, chemical treatment, or beyond.

Taking an Engineered, Integrated Approach to External Corrosion Management

In a panel discussion, Enbridge’s Keith Parker, Corrpro’s Trey Johnston, and Elsyca’s Christophe Baete explain how a collaborative process known as the Engineered, Integrated Approach to External Corrosion Management (IECM) could change the industry.

Pittsburgh Bridge Showed ‘Major Decay’ Months Before Collapse

The Pennsylvania Department of Transportation released an inspection report completed on the Fern Hollow Bridge four months before its collapse, which appeared to show major structural decay. Despite findings from the fall 2021 inspection, no immediate repairs were ordered.

Ceramic Epoxy Liner Makes Settling Basins Watertight

Induron Protective Coatings recently teamed up with Texarkana Water Utilities to develop specifications for several of their uncoated and aging settling basins, which were in critical need of refurbishment. In this case study, learn how a ceramic epoxy liner became the solution.

IMPACT PLUS: How One Company Is Helping Themselves and the Industry

Corrosion management audits are beneficial to participating companies because they identify where opportunities are to improve internal processes and procedures. Gaps are often found between different business or geographic units.

Nominations Sought for 2023 MP Corrosion Innovation Awards

Since 2014, the MP Corrosion Innovation of the Year Awards program has provided a forum for innovative professionals to showcase their corrosion mitigation technologies and receive recognition for their solutions. Winners are selected by a diverse industry panel.
