U.S. Army Extends Contract for Non-Corrosive Deicer Development

OCOchem was awarded a contract extension to create a chemical process to manufacture a lower-cost, non-corrosive, chlorine-free deicer to protect U.S. Army and other military equipment from damage caused by rock or road salt.

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.

U.S. House Introduces Bridge Corrosion Prevention and Repair Act

Introduced over the summer of 2022, the proposed federal legislation would require corrosion planning and the use of qualified and trained professionals on all bridge construction, repair, and maintenance projects throughout the country.

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.

Material Selection for Use in Solar Power Generation

First developed for use in the oil and gas industry, superalloy N07740 is now being used in solar power receiver tubes due to the desire to reduce CO2 emissions. These particular tubes have a heat transfer agent (molten salt) that transfers and stocks solar energy.

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.

U.S. Study Calls for More Oversight of Offshore Oil, Gas Pipelines

According to a study from the U.S. Government Accountability Office, a more robust oversight process is needed to ensure the integrity of approximately 8,600 miles of active offshore oil and gas pipelines in the Gulf of Mexico. New proposed rules are expected by late 2022.

Metallurgical Analysis of Hydrotested ERW Pipeline

In this case study, metallurgical analysis was performed on a carbon steel pipeline that leaked during hydrotesting. An inspection indicated the presence of a defect at the electric resistance welded seam, and it was determined to have formed due to incomplete fusion during welding.

Soil Corrosivity Investigation via Physical and Chemical Composition

In this work, soil corrosivity of the central desert of Iran was investigated by analyzing the physical-chemical characteristics of soils, weight loss testing, and electrochemical measurements.

Cornell, U.S. Navy Raise Bar for Autonomous Underwater Imaging

Tests conducted by Cornell and the U.S. Navy used new algorithms to outperform state-of-the-art programming for autonomous underwater sonar imaging, which significantly improved the speed and accuracy of identifying corrosion on ship hulls and other potential hazards.

Mechanistic Modeling for Integrated External Corrosion Management

With the increasing amount of high-voltage power line corridors, pipeline crossings, and transit systems, interference threats on pipeline assets are more common. This results in a higher risk of accelerated corrosion with poor notification to the pipeline operator.

Naval Aviation Environmental Severity Correlation: 17 Site Assessments

Naval Research Laboratory Key West is a state-of-the-art testing facility for atmospheric and marine corrosion. A two-phase, multi-year severity assessment was recently conducted to compare 16 sites to Key West.

Robotics Used as Unique Tunneling Technology for Utilities

Petra has developed the first non-contact, thermal-drilling method that can uniquely bore 60-in (152.4-cm) diameter micro tunnels through hard rock, making it possible to bore utility tunnels through previously impenetrable geologies.

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.
