Corrosion Types and Damage Mechanisms

Corrosion consists of a series of usually complex chemical reactions and may be initiated by several different mechanisms that are dependent on the surrounding environment. This has given rise to the various classifications of corrosion.

All corrosion is not equal. The key to effective corrosion prevention and mitigation lies in a basic understanding of the type of corrosion being dealt with and the factors that are responsible for its formation. In this sub-module we will look at the most common types of corrosion and explain the underlying mechanism of each.

  • Uniform Corrosion

  • Galvanic/Bimetallic Corrosion

  • Crevice Corrosion

  • Pitting Corrosion

  • Intergranular Corrosion

  • Selective Leaching

  • Erosion Corrosion

  • Stress Corrosion Cracking

ASM corrosion of weldments Hand Book

2006

This book details the many forms of weld corrosion and the methods used to minimize weld corrosion. Chapters on specific alloys groups--carbon and alloy steels, stainless steels, high-nickel alloys, and nonferrous alloys--describe both general welding characteristics and the metallurgical factors that influence corrosion behavior. Corrosion problems associated with dissimilar metal weldments are also examined. Case histories document corrosion problems unique to specific industries including oil and gas, chemical processing, pulp and paper, and electric power. Special challenges caused by high-temperature environments are discussed. Commonly used methods to monitor weld corrosion and test methods for evaluation of intergranular, pitting, crevice, stress-corrosion cracking, and other forms of corrosion are also reviewed.

Corrosion Engineering

1987

The book is designed to serve many purposes: It can be used for undergraduate courses, graduate courses, intensive short courses, in-plant training, self-study, and as a useful reference text for plant engineers and maintenance personnel. Professors in metallurgical engineering, materials engineering, materials science, chemical engineering, mechanical engineering, chemistry, or other physical science or engineering disciplines could teach a beginning course using this text without extensive background or much work in preparation. Section 2-15, "Study Sequence," suggests different procedures depending on the "needs" of the students, plant personnel, and others.

API RP 571 - Damage Mechanisms Affecting Fixed Equipment in The Refining Industry

2020

This recommended practice discusses damage mechanisms applicable to oil refineries; however, much of the information herein can also be applied to petrochemical and other industrial applications, as the user deems appropriate. It is up to the user to determine the applicability and appropriateness of the information contained herein as it applies to their facility. API 571 is a reference document that provides useful information by itself and also complements other API standards and recommended practices. The document should be utilized as a reference to other integrity related documents.
