Why Welding Quality Matters to AMPP Members and Beyond

Jason Becker, a highly experienced welder/fabricator with 25 years of hands-on experience in the welding industry, shares his perspective on why welding quality is of paramount importance to AMPP members and other key stakeholders.

U.S. Bridge Corrosion Prevention Bill a Positive Step for AMPP

Both houses of Congress call their newly introduced bills the Bridge Corrosion Prevention and Repair Act of 2023. The legislation would require corrosion planning while using qualified and trained professionals on all U.S. bridge construction, repair, and maintenance projects.

Examining Galvanic and Deposition Corrosion

Corrosion engineers are familiar with the galvanic series, which lists noble and active metals, and with galvanic corrosion. This article looks at corrosion damage to aluminum caused by direct metal-to-metal contact with copper and by contact with copper-containing solutions.

How Stress Corrosion Cracking Led to Arizona Pipeline Blast

U.S. National Transportation Safety Board (NTSB) investigators believe a deadly natural-gas pipeline explosion in rural Arizona resulted from gaps in protective tape wrapping. This led to water leakage and corrosion and cracks along a seam weld.

How Artificial Intelligence Can Help Design Advanced Materials

Researchers from Germany’s Max Planck Society are introducing a new machine learning model, which they believe will enhance the predictive accuracy of corrosion-resistant alloy designs.

Air Force Trials New Corrosion Control Plan at Guam Base

At the U.S. Andersen Air Force Base in Guam, the equipment maintenance team is employing a new method of limiting corrosion and extending service life on trailers by switching from stainless steel to copper-nickel alloy brake lines.

Prevention Reduces Corrosion Costs in Power Industry

Elevated temperatures, harsh environments, and abrasive materials make corrosion costly to the power-generating industry. Fortunately, utilities can save on these costs by making appropriate choices in materials and coatings while monitoring conditions.

Advances in Protecting Pipelines from Hurricane Damage

With the Northern Hemisphere’s 2023 hurricane season in full swing and nearing its annual peak, emerging technologies and artificial intelligence are among new tools offering hope for superior pipeline protection against mighty storms.

Superlubricity Coating Aims to Reduce Losses from Friction, Wear

Scientists at Oak Ridge National Laboratory have invented a coating that could dramatically reduce friction in common load-bearing systems with moving parts, such as vehicle drive trains and wind and hydroelectric turbines. It reduces the friction of steel rubbing on steel by at least a hundredfold.

Study: U.S. EPA’s Lead, Copper Rule Exceeds Financial Estimates

The U.S. Environmental Protection Agency’s revised lead and copper rule for drinking water costs $335 million to implement while generating $9 billion in annual health benefits. According to a university study, this significantly exceeds prior projections.

AMPP’s Alan Thomas Outlines Priorities as New CEO

Effective April 1, 2023, Alan Thomas became the new CEO of the Association for Materials Protection and Performance (AMPP). In this exclusive interview, AMPP’s new leader introduces himself while expressing some initial priorities.

PHMSA’s New Rule Updates Pipeline Corrosion Control Requirements

Tyler Laughorn, corrosion control specialist at Burns & McDonnell, explains what industry professionals need to know regarding PHMSA’s recently finalized rule on protective coatings, cathodic protection surveys, and internal corrosion monitoring and mitigation for gas transmission pipelines.

U.S. Army Lead Explains Nondestructive Testing, Corrosion Program

Tim Goddette, deputy assistant secretary for sustainment, recently visited Aviation and Missile Command headquarters at Redstone Arsenal, Alabama, to discuss the U.S. Army’s nondestructive testing and corrosion program.

Internal Near Neutral pH SCC in Carbon Dioxide Gathering Lines

In this technical article, learn how recent investigations of internal butt-weld cracks—associated with flowlines gathering wet supercritical carbon dioxide—determined near-neutral pH stress corrosion cracking to be the cause.

New Modeling Approach for Predicting Corrosion Under Insulation

Building information modeling aims to streamline the inspection of piping insulation by identifying and flagging high-risk areas, which inspectors can use to cover more ground while increasing the likelihood of finding corrosion.
