Corrosion Basics

Corrosion Basics—Types of Corrosive Atmospheres

Although atmospheres can be classified into four basic types, most of them are mixed and present no clear lines of demarcation. Furthermore, the type of atmosphere may vary with the wind pattern, particularly where corrosive pollutants are concerned.

Corrosion Basics—Corrosion Surveys

Two of the most fundamental and informative field measurements are soil resistivity surveys and pipe-to-soil potential surveys.

Corrosion Basics—Water Constituents

In water, the concentrations of various substances in dissolved, colloidal, or suspended form are typically low, but may vary considerably depending on the components and usage. For example, hardness values of up to 400 parts per million of calcium carbonate is sometimes tolerated in public supplies of potable water, whereas 1 ppm of dissolved iron would be unacceptable.

Corrosion Basics: Protecting Fixed Structures in Seawater

Steel structures such as bulkheads, piles, offshore drilling platforms, etc., may be protected with either sacrificial galvanic anode or impressed current cathodic protection systems.

Corrosion Basics: Special Cathodic Protection Requirements for Specific Pipeline Applications

Most pipeline cathodic protection applications involve either galvanic anode or impressed current systems installed in earth for protection of external surfaces.

Corrosion Basics: Testing Protective Coatings

Coating operations of almost any size must include some type of meaningful test program.

Corrosion Basics: Steam Generation in Power Plants

The greatest use of high-temperature water and steam is in electrical power generation.

Historic Corrosion Tools Tell the Story of Early Corrosion Control

A collection of antique instruments illustrates the rich history of the East Bay Municipal Utility District’s corrosion department.

Strategic Planning at NACE International: Series Finale

The key to effective planning involves converting decisions to actions. For the process to be most effective, the results of the actions are monitored and shared, thus continuing an unending process.

Strategic Planning at NACE International: Implementation Plan

In the 10th part of this series, we explain how the implementation plan is a tool that can be used to break annual key strategies into increasingly smaller tasks.

Strategic Planning at NACE International: Ninth in a Series

A number of board key strategies and definitions of success were agreed upon at the fall 2017 meeting of the NACE International Board of Directors.

NACE International Celebrates its Diamond Anniversary in 2018

Next year the association celebrates its Diamond Anniversary, a milestone made possible by the knowledge, expertise, and continued support of its members from around the globe.

Strategic Planning at NACE International: Eighth in a Series

Given that the October print issue of MP is focused on CORROSION 2018, it seems appropriate to describe some of the strategic planning-related activities that will occur at this upcoming conference.

Strategic Planning at NACE International: Sixth in a Series

The overarching goals create a specific, measurable, and attainable verbal picture of what our association will look like by October 2019.
