Asset Management

Asset Performance Management Improvement by the Numbers

Supply and demand out of phase, finished goods and raw materials supply chains disrupted, energy costs instability, and skilled workers shortages are all common concerns across the globe. Solutions for relief are paramount. In these troubling times of global financial uncertainty any improvements in how we operate our equipment is sought. It is said that the product of asset management (AM) is reliability, that is, poor management equals poor reliability and good management practices will provide good equipment reliability.

The Edison Principal – More Science than Guesswork for Corrosion Prevention

The Edison Principal has been developed to solve America’s $1.2 trillion corrosion expense by replacing visible rust with black light active fluorescence. Edison Principal is an analogy based on the failure indicator of the common light bulb invented by Thomas Edison.

Brinelling and False Brinelling

What is the difference between Brinelling and False Brinelling? What causes Brinelling and False Brinelling? Brinelling is an indentation in the surface of a material; a permanent plastic deformation that occurs when the yield strength of the material has been exceeded.

Common Mechanisms of Failure & Preventive Methods

Why do components fail? – This article explains common failure mechanisms, component types to which each applies, and suggests non-intrusive monitoring techniques to discover components in various stages of progressive failure.

Linear and Nonlinear Vibrations

Linear and nonlinear vibrations as they pertain to machinery vibration monitoring are not hard concepts to grasp when properly explained. Alian Friedman of Zenco – Vibration Experts, explains the concepts in an easy-to-understand, non-mathematical way.

Gaps in Your Electric Motor Reliability Program

Costly oversights occur repeatedly despite thoughtful planning dedicated to maximizing the operation and lifespan of the motor. One unsettling realization is that testing, considered part and parcel of preventive maintenance, is not preventing anything because there is nothing to indicate that analyzing the data was even considered. This is a major pitfall and a classic example of a gap in a company’s motor management program.

Root Cause

Definition of Root Cause Analysis (RCA)

A fault tree is constructed starting with the final failure and progressively tracing each cause that led to the previous cause. This continues till the trail can be traced back no further. Each result of a cause must clearly flow from its predecessor (the one before it). If it is clear that a step is missing between causes it is added in and evidence looked for to support its presence. Below is a sample fault tree for the moral story of the kingdom lost because of a missing horseshoe nail.

The Trifecta of Motor Maintenance

Using the same concept of a trifecta (three factors for success), this article provides companies with the winning strategies of motor maintenance, focusing on the three reliability tasks for electric motor testing and the order in which they should be applied. Following these steps will drastically improve their odds in motor reliability and put a big payday at the end of their production goals.

Piping Vibration – Causes, Limits and Remedies

We are embarking on a voyage of discovery that entails us calling at the following way stations:
Part 1 – Calculate natural frequency of a pipe
Part 2 – Calculate VIV Vortex
Induced Vibration affecting the pipe
Part 3 – Calculate the effect
of flow induced vibration as flow rates change
Part 4 – Determine the severity of the vibration to see if it is acceptable as is or if we need to make modifications.
