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

API RP 571, Damage Mechanisms Affecting Fixed Equipment in the Refining Industry, is a recommended practice developed and published by the American Petroleum Institute (API) that provides an in-depth look at nearly 70 different
Corrosion and Materials

Corrosion and Materials is a field of study that focuses on understanding the causes and mechanisms of corrosion. According to API 510...
Damage Mechanisms

Damage Mechanism is a general term used to describe mechanical or chemical processes that result in equipment damage or material degradation. These can range from corrosion, to...
Finite Element Analysis (FEA)

Finite Element Analysis (FEA) is a computerized system of theoretical modeling used to predict stress locations and causes of failures in different materials. This method is useful for simulating, modeling, and analyzing problems that could affect complicated systems, such as...
Fitness For Service (FFS)

Fitness for Service (FFS) is a best practice and standard used by the oil & gas and chemical process industries for in-service equipment to determine its fitness for continued service. FFS serves as a rational basis for defining flaw acceptance limits and allows engineers to...
High-Temperature Creep

Creep damage is a time-dependent phenomenon characterized by gradual, continuous deformation, affecting all metals and alloys, under the combined action of temperature and stress. In general, creep damage accumulation and the propensity for...
Inspection

Inspection is the practice of examining the physical condition of materials, components, or entire pieces of equipment in order to determine if and for how long it will operate as intended. Inspection plays a vital role in any
Mechanical Integrity (MI)

Mechanical Integrity (MI) can be defined as the management of critical process equipment to ensure it is designed and installed correctly, and that it operates and is maintained properly (i.e. no leaks and all elements are fit for service). A mechanical integrity program should...
Reliability

Reliability is a special attribute that describes the dependability of a component. This means that the component consistently performs a desired function under certain conditions for a certain period of time in order to meet business goals and...

November/December 2022 Inspectioneering Journal

Part 2 of this Damage Control series on high-temperature creep discusses engineering evaluation methods that can be used to predict the remaining creep life of components. Comparisons between the Larson-Miller Parameter and the MPC Omega are offered.
Damage Control: Stress Corrosion Cracking Detection

March/April 2022 Inspectioneering Journal

This article provides an overview of some of the more common forms of stress corrosion cracking (SCC) with a focus on effective inspection methods for detecting these forms of cracking.
Damage Control: Stress Corrosion Cracking Assessment

May/June 2022 Inspectioneering Journal

Part 2 of the three-part series on stress corrosion cracking (SCC) that examines common engineering and FFS methods that can be leveraged to understand and evaluate the propensity for an existing form of SCC to lead to loss of containment.

Overview

High-temperature creep is a time-dependent phenomenon characterized by gradual, continuous deformation, affecting all metals and alloys, under the combined action of temperature and stress.

This eBook will focus on typical damage morphology and inspection methods used to identify and characterize high-temperature creep. A high-level overview of creep behavior in carbon steels and other alloys will also be presented, and generally accepted temperature thresholds defining the lower boundary of the creep regime for varying materials will be discussed.

Additionally, commonly affected pressure equipment in the oil and gas, petrochemical, power generation, and related industries will be outlined, and critical factors influencing damage susceptibility will be reviewed. Furthermore, examples of creep damage and in-service failures will be summarized to offer insight into this complex damage mechanism.
