MTI Book Complements API Damage Mechanisms Recommended Practices

MTI’s book, Guidance for Failure Mechanisms, provides an overview of the most prevalent failure mechanisms in the Chemical Processing Industry. The recently published guide (June 2020) is designed to complement API 571, Damage Mechanisms Affecting Fixed Equipment in the Refining Industry, by focusing on the types of damage mechanisms found in the chemical process industry that are not common in the oil and gas industry. The book’s 39 chapters describe where, how, and why these types of failure occur, how they can be inspected and detected, and how to prevent them from occurring in the first place. Failure Mechanisms Cover

Project contractor Becht used data shared by many of MTI’s member companies to develop the book. The guide covers many potential failure mechanisms, including erosion, abrasion, fracture, galling, pitting corrosion, corrosion fatigue, flow induced corrosion, cryogenic failures, crevice corrosion, intergranular corrosion, microbiologically influenced corrosion, stress corrosion cracking, stress relaxation cracking, metal dusting, and high temperature hydrogen attack (HTHA). While information on many of these mechanisms can be found online, it is often incomplete or misleading. One of the strengths of this volume is not only the compilation of damage mechanisms applicable to our plants, but the extremely high level of expertise and experience of the authors, combined with the vetting and review of the MTI community, which results in a reference document that is thorough and reliable. Each mechanism also compiles a list of credible references for further investigation and information.

According to MTI Project Champion Lars Rose, DuPont, the in-depth information provided by subject matter experts will help engineers streamline maintenance tasks and act as a helpful resource for inspections. “Everybody who holds this document in their hand has a solid reference that can be used to identify, predict, treat, and prevent failures in their facilities that could result from one of the almost three dozen mechanisms chosen for this book,” he explains. “These are not all-encompassing, and several other mechanisms exist, but the major ones that may be expected at many of our plants are included. As a result, this work serves to reduce the risk of incidents and resulting personal injuries as well as the loss of business opportunities, making the operation of chemical, petrochemical, pharmaceutical, and food/beverage industries much safer and more profitable.”

Guidance for Failure Mechanisms is currently available in digital and print formats, but exclusively to MTI member companies. For more information about membership, contact Kirk Richardson at krichardson@mti-global.org.
