Telluric currents shift a pipeline's potential during geomagnetic activity while the rectifier reads normal. Here's what the research shows and what to monitor.

AWWA D106 governs sacrificial anode systems for steel water tank interiors. Here's what the standard requires for anode material, sizing, and placement.

Offshore wind foundations face corrosion challenges that differ from oil and gas platforms. Here's how cathodic protection design needs to adapt.

EPA plans a 2026 proposal limiting PFAS discharges from chrome plating wastewater. Here's what's driving it and what platers should watch for.

Pipelines near high-voltage AC lines face a corrosion risk standard CP design doesn't cover. Here's what AC mitigation under NACE SP21424 actually requires.

PEM electrolyzers need titanium for corrosion resistance and conductivity. As green hydrogen scales, that's a new claim on an already tight titanium supply chain.

California's Air Resources Board voted to phase out hexavalent chromium at the state's 117 chrome-plating facilities, with decorative operations required to stop by 2030 and functional operations getting until 2039. That single regulatory action has done more to accelerate the trivalent chrome conversation nationally than a decade of environmental advocacy did on its own. Shops outside California are watching closely, because CARB rules have a track record of becoming the de

Two Ways to Push the Same Electrons Both systems do the same job: they turn the pipeline into the cathode in its own corrosion cell so the steel stops giving up electrons to the surrounding soil. The difference is where those electrons come from. A galvanic system relies on a more reactive metal — magnesium, zinc, or aluminum — that corrodes on purpose so the pipeline doesn't have to. An impressed current system (ICCP) uses an external DC power supply (a rectifier) to push cu

PHMSA has proposed the first major rewrite of federal pipeline repair standards in more than twenty years, and it's the kind of regulatory update that doesn't grab headlines but changes how integrity and CP data get used day to day.

Ask five engineers how many anodes a given pipeline segment needs and you'll sometimes get five different answers, usually because someone started with anode count instead of current demand. Sizing a galvanic system correctly means working the problem in the right order: figure out how much current the structure needs first, then work backward to how many anodes deliver it -- reversing that order is where most oversized or undersized systems come from. Start With Current Dema

For decades, innovation in manufacturing was largely driven by software, automation, and production efficiency. But today, another transformation is quietly reshaping the industrial world: the race for lighter, stronger, smarter materials. From aerospace and defense to EVs, energy infrastructure, electronics, and industrial manufacturing, advanced materials are rapidly becoming one of the most important competitive advantages in modern engineering.

Titanium has become an indispensable material in various industries, from aerospace to medical to chemical processing. Its journey from raw

When it comes to surface finishing, the choice between hexavalent chrome and trivalent chrome plating extends far beyond mere aesthetics.

The PHMSA Mega Rule is a set of regulations by the Pipeline and Hazardous Materials Safety Administration (PHMSA).

Pipeline transportation emits 0.44 grams of CO2e per ton-mile for crude oil. Rail emits 4.4 grams. Trucks emit 19.6 grams. That is not a close comparison: pipelines are 10 times cleaner than rail and 45 times cleaner than truck transport per unit of product moved. On efficiency alone, pipelines are not really in competition with other modes. The debate about pipeline investment often misses this point. Despite the growth of renewable energy, the International Energy Agency pr

In this blog post, we will explore the differences between synthetic graphite powder, natural flake graphite powder, and graphene, as well a

At its core, galvanic corrosion occurs when two dissimilar metals come into contact in the presence of an electrolyte, leading to the accele

Over the last couple years mixed metal oxide anodes have grown exponentially in popularity. They are light, easy to work with, have a high a

We explore the impact of ribbon cross-sectional shapes on current distribution using the laws of physics.

At the core of urban water distribution, cast iron and ductile iron pipelines have been doing the same job for well over a century. Most people never think about them. The engineers maintaining them think about them constantly. Cast Iron: 1800s to 1960s Cast iron pipelines pioneered water distribution infrastructure in the 19th century. Wall thicknesses typically ranged from 0.5 to 1 inch, and initial design life assumptions of 40 to 60 years seemed conservative at the time.
