Strategic Planning at NACE International: Fourth in a Series

The third and final aspect of defining our core ideology relates to the question, “What is it that we do?” In strategic planning parlance, this is called a mission statement. A mission statement describes what we do to fulfill our core purpose. Let’s recall our core purpose, or why we exist in the marketplace.

Strategic Planning at NACE International: Third in a Series

Last month we defined ideology as a body of beliefs that guide individuals or large groups. To define our core ideology, the NACE International Board of Directors recognized that we must answer three questions.

Corrosion Basics: Stress Corrosion Cracking

Stress corrosion cracking (SCC) is a mechanical-chemical process leading to the cracking of certain alloys at stresses below their tensile strength.

Strategic Planning at NACE International

Strategic planning is a process that provides a roadmap for taking our association from a well-defined present state, to a compelling and significantly different future state.

Corrosion Basics: High-Temperature Corrosion

High-temperature corrosion does not require the presence of a liquid electrolyte. In this corrosion mechanism, metals react directly with gaseous atoms in the atmosphere rather than ions in solution. Sometimes, this type of damage is called “dry corrosion” or “scaling.”

Corrosion Basics: Coating Concrete

Before a concrete structure can be coated, it is necessary to understand and overcome concrete's natural properties.

NACE Publishes Revised Coating and Lining Application Specialist Training and Certification Standard

The 2016 revised NACE No. 13/SSPC-ACS 1, “Industrial Coating and Lining Application Specialist Qualification and Certification” standard includes up-to-date information for qualifying the coatings and linings application specialist.

Corrosion Basics: Open Recirculated Cooling Water Systems

There are certain fundamental considerations that should be understood in relation to open recirculated systems.

Corrosion Basics: Coating New Construction Seagoing Vessels

Surface preparation and coating application during the new construction of a vessel compose a complex orchestration that requires the coordination of every department in a shipyard. It is also one of the most expensive parts of building a new vessel.

Corrosion Basics: Locating Pipeline Coating Defects with a Pearson Survey

One of the first successful techniques for locating coating defects (holidays) on buried pipelines using surface electrical measurements is the Pearson survey, named after its inventor.

Results Posted for NACE International’s 2016 Annual Corrosion Career Survey

Average annual salaries in 2016 are reported for corrosion professionals in the United States, Canada, United Kingdom, and Europe. A slight gain was seen for the United States and United Kingdom, while a larger increase was recorded in Canada.

Corrosion Basics: ICCP for Atmospherically Exposed Reinforced Concrete Structures

Impressed current anodes for atmospherically exposed steel in concrete are very different from anodes for underground and underwater applications.

Corrosion Basics: Stray Current Effects

Where stray currents discharge from a structure into the electrolyte environment in order to return to the source, corrosion will occur. If the corrosion is concentrated over a limited surface area, the integrity of the structure may be threatened in a relatively short period.

Corrosion Basics: Steam Generation in Power Plants

The greatest use of high-temperature water and steam is in electrical power generation. Historically, fossil fuels were used almost exclusively to heat water for steam until the introduction of nuclear power steam generators. This article briefly summarizes corrosion considerations for fossil fuel and nuclear fuel steam plants.

Corrosion Basics: Close-Interval Potential Surveys

The principle of a close-interval potential survey is to record the pipe-to-soil potential profile of a pipeline over its entire length by measuring potentials at intervals that do not significantly exceed the depth of the pipe.
