This book is designed for engineering and skilled trades personnel involved in improving machinery maintenance and reliability. It explains the four major failure mechanisms and how to identify them. Knowing the physical failure mechanics involved, the reader can then solve the physical and human causes.

This totally revised, updated and expanded edition provides proven techniques and procedures that extend machinery life, reduce maintenance costs, and achieve optimum machinery reliability. This essential text clearly describes the reliability improvement and failure avoidance steps practiced by best-of-class process plants in the U.S. and Europe.

This is a practical guide for those who do the work of maintaining and improving the reliability of mechanical machinery. It is for engineers and skilled trades personnel who want to understand how failures happen and how the physical causes of the great majority can be readily diagnosed in the field. It explains the four major failure mechanisms, wear, corrosion, overload, and fatigue and, using easy-to-read charts, how they can be diagnosed at the site of the failure. Then, knowing the physical failure mechanics involved, the reader can accurately solve the human causes. To improve the reader’s understanding, all the diagrams and most of the tables have been redrawn. The number of actual failure examples has been increased, plus the last chapter on miscellaneous machine elements includes new material on couplings, universal joints, and plain bearings. Features A practical field guide showing how to recognize how failures occur that can be used to solve more than 85% of mechanical machinery failures Incorporates multiple easy-to-follow logic trees to help the reader diagnose the physical causes of the failure without needing detailed laboratory analysis Explains how the mechanics, corrosion, materials science, and tribology of components can fit together to improve machinery reliability Includes more than 150 completely redrawn charts and tables, plus almost 250 actual failure photographs to help guide the reader to an accurate analysis Contains clear and detailed explanations of how lubricants function and the critical roles of corrosion and lubrication play in causing mechanical failures

To maintain competitiveness in the emerging global economy, U.S. manufacturing must rise to new standards of product quality, responsiveness to customers, and process flexibility. This volume presents a concise and well-organized analysis of new research directions to achieve these goals. Five critical areas receive in-depth analysis of present practices, needed improvement, and research priorities: Advanced engineered materials that offer the prospect of better life-cycle performance and other gains. Equipment reliability and maintenance practices for better returns on capital investment. Rapid product realization techniques to speed delivery to the marketplace. Intelligent manufacturing control for improved reliability and greater precision. Building a workforce with the multidisciplinary skills needed for competitiveness. This sound and accessible analysis will be useful to manufacturing engineers and researchers, business executives, and economic and policy analysts.

Component failures result from a combination of factors involving materials science, mechanics, thermodynamics, corrosion, and tribology. With the right guidance, you don’t have to be an authority in all of these areas to become skilled at diagnosing and preventing failures. Based on the author’s more than thirty years of experience, Practical Plant Failure Analysis: A Guide to Understanding Machinery Deterioration and Improving Equipment Reliability is a down-to-earth guide to improving machinery maintenance and reliability. Illustrated with hundreds of diagrams and photographs, this book examines... · When and how to conduct a physical failure analysis · Basic material properties including heat treating mechanisms, work hardening, and the effects of temperature changes on material properties · The differences in appearance between ductile overload, brittle overload, and fatigue failures · High cycle fatigue and how to differentiate between high stress concentrations and high operating stresses · Low cycle fatigue and unusual fatigue situations · Lubrication and its influence on the three basic bearing designs · Ball and roller bearings, gears, fasteners, V-belts, and synchronous belts Taking a detailed and systematic approach, Practical Plant Failure Analysis thoroughly explains the four major failure mechanisms—wear, corrosion, overload, and fatigue—as well as how to identify them. The author clearly identifies how these mechanisms appear in various components and supplies convenient charts that demonstrate how to identify the specific causes of failure.

Here is the ultimate reference for ascertaining the functionality and remaining life of industrial process equipment. Packed with graphs, figures, photos, and checklists, this edition of An Introduction to Machinery Reliability Assessment is the most approachable and useful book on this topic. This single volume contains dozens of assessment techniques based on probability and statistical analysis. Theoretical and practical contexts are given for the various methods, which include failure mode and effect analysis, risk and hazard assessment, fault tree analysis, Weibull analysis, and field reliability assessment. The second edition now contains expanded treatments of turbomachinery (particularly centrifugal pumps), Weibull analysis techniques, and equipment safety checklists. Most importantly, it includes a new chapter focusing on mechanical structures and piping. New appendixes on safety design checklists and installation reviews and an updated glossary enhance the book's utility and practical application, making it a complete single source of machinery reliability assessment techniques.

For too long, maintenance has been regarded as a ""necessary evil"" rather than a vital contributor to effective mining operations. Today's enlightened mining managers are realizing that a new approach is urgently needed. Quality maintenance is far too important to be left solely in the hands of maintenance. An integrated, well-understood, companywide strategy is essential to succeed in today's fiercely competitive, high-stakes marketplace.
