Marine Structures Create Unique Challenges for Third-Party Inspectors

Inspectors with previous marine experience tend to have a better feel for the ebb and flow of a project—however, even experienced marine inspectors may face challenges.
Joe Payer: Preparing the Corrosion Engineers of Tomorrow

The Department of Defense conducted a corrosion cost study to quantify what they had known for years—that corrosion was a huge financial drain on the national and military infrastructure. This is why the industry is crying for well-trained recruits.
Galvanization and its Efficacy in Corrosion Prevention

Galvanization has proved to be a highly cost-effective, sustainable and widely used technique for corrosion prevention. Learn more about it here.

Corrosion Costs & Recommended Practices for the Water Industry

Aging water and wastewater infrastructures are difficult and expensive to manage. But how much does the corrosion problem cost the industry? And how can water utilities better manage corrosion to reduce these costs?
Coating Failure: Why a Preventive Strategy is the Best Way to Avoid it

No coating is better than a bad coating because recoating can cost much more than the initial coating application. Find out how to prevent coating failure by getting things right the first time around.
The Ugliest Coating System You’ve Never Seen

The coating, for all intents and purposes, was perfect. But if this work were to be done today, with a third-party inspector onsite, it would not be approved.
Ice Pigging: New European Pipe Cleaning Innovation

A water infrastructure corrosion expert reviews a paper by researchers at the University of Bristol on an innovative technique called ice pigging for the water supply industry.
7 Methods of Coating Thickness Measurement

Measurement of film thickness can be done with many different instruments. Understanding the equipment available for film thickness measurement is important for every coating operation.
The Corrosion Properties of Aluminum and Its Alloys

Aluminum and aluminum alloys are in widespread use in many industrial applications, with its usage second only to that of steel.
Use of Insulating Coatings for Hazard Protection

Corrosion under insulation (CUI) causes many safety hazards in industrial facilities, many of which are prevented by using thermal insulating coatings.
The Anatomy of a Coating Failure

Rarely does a coating fail because of only one contributing factor. Rather, it is usually two or more factors working in conjunction that cause a coating to fail on a particular site, when that same coating has performed as expected on other sites.
VIDEO: John Oliver on America's Crumbling Infrastructure

Infrastructure: it's our roads, bridges, dams, airports, power grids... basically anything that can be destroyed in an action film! Here's John Oliver's take on the state of America's infrastructure.
Corrosion Assessment: 8 Corrosion Tests That Help Engineers Mitigate Corrosion

Corrosion testing is one of a corrosion engineer's most important responsibilities. Here we look at the top field and laboratory tests used.
Replica Tape: A Source of New Surface Profile Information

After blast cleaning, a surface consists of random irregularities with peaks and valleys. If the roughness is insufficient, paint will not adhere. If the roughness is too great, the surface will be susceptible to corrosion.
Human Error as a Factor in Corrosion Failure

One of the least addressed causes of corrosion is human error. Here we'll take a look at how human error contributes to corrosion failure and what can be done to mitigate its effects.
How to Plan Facility Coatings Condition Assessments

Proper pre-planning and deciding what data to collect are essential to the efficacy and cost effectiveness of both baseline surveys and ongoing inspections for coatings asset management programs.
Emergency In-Situ Repair Problems & Surface-Tolerant Solutions

A new fast-cure, polymeric epoxy-based emergency repair composite provides excellent adhesion without intensive surface preparation, grit blasting, or removal of moisture, oil, or salt contaminants, and can be applied even under water.
Controlling Corrosion in Electronic Devices

The careful selection of coatings and substrate materials based on the service exposure of electrical equipment and controls can improve the reliability and cost effectiveness of the entire system. Learn how to prevent corrosion in electrical systems.
Corrosion Prevention for Water Pumps, Valves, Impellers and Fittings

Pumps, valves, impellers, and fittings are highly susceptible to several types of corrosion, including erosion, galvanic, pitting and cavitation corrosion.
Using Metallization (Thermal Spraying) as Corrosion Prevention

Due to its durability and corrosion protection, metallization (thermal spraying) is an excellent protection method for structures with a long lifespan that are in contact with a water environment, such as bridges and dams.
Combating Sanitation System Corrosion

Sanitation corrosion is a worldwide problem that permeates through a system of moving waste to processing stations, often ending with water reclamation. As these systems become outdated, we need cost-effective, long-term repair and protection solutions.
Corrosion Electrochemistry: The 6 Electrochemical Reactions Involved in Corrosion

Temporary Corrosion Protection during Storage, Transportation and Handling

Preventing temporary corrosion is an essential strategy for winning the battle against material loss due to deterioration of metals during manufacturing stages, transportation and transit storage.
Concrete Flooring Moisture Issues

Addressing concrete floor moisture begins with proper design, curing and surface preparation. Testing for moisture content and identifying its source are very important steps toward controlling moisture within the concrete.
Soluble Salts and Coating Performance

Due to the potential for soluble salts to reduce coating performance, testing the substrate for the presence of these salts should be considered a requirement of the project specification to prevent corrosion.
Aviation Coatings for Corrosion Prevention

Corrosive deterioration of the critical surfaces of aircraft can come in the way of ensuring a reliable and safe operational performance. If the corrosion is not detected and prevented in time, it can endanger human lives.
