Corrosion Effects on the Durability of Reinforced Concrete Structures

Several myths concerning the cause of reinforced concrete deterioration prevailed in the mid-20th century, but steel corrosion is by far the biggest durability issue for reinforced concrete structures.

Eliminating Coating Failures—A Case Study for Achieving Long-Term Cost Savings in the Oil Field

Giving special attention to surface preparation and eliminating surface contaminants prior to coating can essentially eliminate premature coating failure.

Pitting Repairs for High-Temperature/High-Pressure Process Vessels

The most damaging form of corrosion is localized corrosion, which can be prevented and controlled by using corrosion inhibitors, cathodic protection, and protective coatings.

Long-Term Protective Coating Success

Corrosion poses a threat to all infrastructure, and the economic impact of corrosion represents an annual cost of billions of dollars. There are many advantages of planning for corrosion control and mitigation. It is important that owners and operators of high-value assets understand the cost implications of the effects of corrosion.

Understanding a New Standard

The Canadian Standards Association developed CSA Z245.30-141 for external field-applied coatings on steel pipelines. It defines requirements for the qualification, application, inspection, and testing of external oil and gas pipeline coatings applied in the field or shop.

NACE International’s Annual Corrosion Career Survey Results for 2015

Corrosion professionals in North America and Europe have experienced another year of continued growth in career opportunities and salary levels, according to the 2015 Corrosion Career Survey conducted by Materials Performance magazine.

Belzona Case Study on Pipeline Protection

An international oil and gas exploration and production company was looking to enhance oil recovery techniques in Oman. Internal coating of the pipelines provided corrosion protection, reduced friction, and improved flow efficiency when conveying corrosive water slurry, and offered adequate corrosion protection during subsequent transportation of recovered crude oil.

Wanted: Technical Articles for MP

To successfully communicate the wide variety of corrosion-related issues affecting corrosion professionals today, MP is actively encouraging corrosion control professionals worldwide to submit technical articles to share their corrosion-related experiences with over 36,000 NACE International members around the globe.

Advanced Fluoropolymer Fouling-Release Coating

On static structures, such as the steel legs of an offshore oil platform or the hull of an floating production, storage, and offloading (FPSO) vessel, the structural integrity of the welds need to be visually inspected and assessed. If the substrate is covered in biofouling that isn’t easily removed, a large amount of force is required to scrape it off, which may damage the underlying protective coating and leave the substrate vulnerable to corrosion.

Inorganic Zincs—How Do They Cure?

Inorganic zinc (IOZ) coatings are used pervasively in industry to provide reliable protection from corrosion on a variety of substrates. Problems have emerged with coatings applied over zinc primers, however, such as delamination and blistering. This article discusses proper curing methods for IOZs to ensure dependable performance of the entire coating system.

Importance of the ‘Little Things’ in a Good Coating Job

Many years ago, early in my career, I was reminded that it’s the little things that make a standard paint job a good paint job. Coatings are too often thought of as something that must be done, but it’s not necessary to spend much time on surface preparation or application. After all, “paint is paint and anybody can apply paint.”

Service Life Extension for Protective Coatings

Because of increasing costs, owners are demanding longer coating service life. Ten to 15 years is no longer satisfactory. Simply adding dry film thickness will not work since many coatings crack at excessive thicknesses. Recent coating technology advances permit the use of solvent-free epoxy and polyurethane systems having >15-year lives. Newer combinations of epoxy and polysiloxane resins will make a 25-year life achievable.

Predicting Coating Life

The prediction of coating life depends on many factors, including the coating system used, preparation and application methods, and the severity of the environment. This article describes the knowledge needed to estimate coating life and the conditions that can compromise coating systems.

The Importance of the Pre-Job Meeting

A thorough pre-job meeting is an essential part of any project. This article covers the requirements of a pre-job meeting before starting a coating project. It presents advice on who should attend, the roles of the attendees, and references needed.

Managing a Coating & Plating Supply Chain

Re-engineering supply chains can reduce costs, cut delivery times, provide a significant competitive advantage, and enhance customer relationships. Supply chain concepts can be applied to the finishing phase (coating or plating) of production to further cut costs and delivery times.
