A continually frustrating phenomenon to many of us is the situation where a tight bolt will function satisfactorily, but in the same situation, a loose bolt will fail...
In the previous issue we dealt with the fact that bolts can withstand significantly less cyclic loading than steady loading. We are now looking at the mechanics of why bolts fail if flanges are allowed to separate during operation.
In two previous issues we discussed the important difference between steady and cyclic loading, and why loose bolts fail while tight ones do not. This issue will offer two suggestions for reducing the tendency for bolts to become loose.
Deterioration of concrete structures has plagued petrochemical production facilities. As a result of sulfur compound exposure, concrete corrodes and weakens continuously over time. The proper operation of the structure deteriorates with it until...
Washington DC, January 27, 2011 - A U.S. Chemical Safety Board (CSB) case study released today on the 2008 heat exchanger rupture and ammonia release at the Goodyear Tire and Rubber Company in Houston, Texas, identifies gaps in facility emergency...
The U.S. Chemical Safety Board (CSB) today released its final report on a series of three accidents that occurred over a 33-hour period on January 22 and 23, 2010, at the DuPont Corporation's Belle, West Virginia, chemical manufacturing plant -...
In the summer of 2005, as part of CIA Inspection's (CIAI) ongoing, in house, research efforts to improve inspection capabilities for coke drums, a development program was initiated to integrate ACFM (Alternating Current Field Measurement) inspection...
The most common equipment vibration problems are often solved in industry without the use of specialty engineering resources. Routine vibration problems-from machinery imbalance and misalignment to simple cases of noise and resonance-are often...
Describes a non-destructive sampling procedure which records and preserves the topography of a metallographic specimen as a negative relief on a plastic film (replica).
The morning meeting at the plant was a tough one for you. As an area engineer you are not satisfied with the information you are receiving from your team's investigation into a major compressor wreck that has happened once again. The conclusion...
Once again there is a crack found in the inlet tubesheet in your high-pressure high temperature heat exchanger. As head of the maintenance engineering effort, you know that plant management will ask you if it can run safely and reliability until...
As the technology of NDT systems improve, it is important to assure that the people and processes using this technology are adequately prepared in order to take full advantage of the enhancements of the system.
Leaks or spills over the life of nuclear power plant operation can lead to undesirable consequences. The nuclear industry’s GroundwaterProtectionInitiativeandthelessonslearnedand experiences gained from implementing groundwater protection...
Whether you decide for a Computed Radiography scanner with flexible imaging plates or a flat panel detector with the fastest imaging, or even combine the advantages of both technologies, DÜRR NDT's innovative systems offer high reliability and the...
Tri-Lateral Phased Array is a novel robotic phased array ultrasonic testing technique for the on-stream inspection of fixed equipment in wet hydrogen sulfide (H2S) service. TriLat identifies and quantifies wet H2S damage in the base metal of...
EPRI is investigating improved inspection technologies as part of a multi-faceted effort to enhance the understanding and management of underground piping and tanks at nuclear power plants. An ultrasonic immersion technique tested on an...
Putting off the initial inspection (i.e. baseline) of piping and vessels in a new process unit is both common and problematic. The tendency of owners is to rely on the nominal thickness because the actual original thickness was either not measured...
The original article on scalable accuracy which laid the groundwork for the concept was published in the March April 2011 issue of the Inspectioneering Journal, entitled Scalable Accuracy, Key Roles of Risk Based Inspection and Fitness for Service,...
Three new recommended practices (RP) are under way within the API Inspection Subcommittee (SCI) which will add to the list of SCI standards available to owner-users to improve their mechanical integrity (MI) and inspection programs.
Due to increasing market demands for stabilized crude, it is a high priority for oil handling and processing facilities to avoid production interruption. One optimization opportunity is to review our approach for scheduled facility Test and...
Two technologies, immediately available to plant operators for fixed equipment life-cycle management are Risk-Based Inspection (RBI) and Fitness for Service (FFS), two best practices that optimally work together or can standalone. Both have...
On October 7, 2010, EPA maintained the November 10, 2010 compliance date for drilling, production or workover facilities that are offshore or that have an offshore component, and for onshore facilities required to have and submit Facility...
Tesoro Corporation announced the release of the TOP (Triangle of Prevention) Investigation Team Report on the April 2, 2010, incident at the Anacortes Refinery in Washington State.
Maintenance has been around since prehistoric man fixed a broken, trusted spear instead of fashioning a new one. One concept of maintenance is any activity that extends the useful life or enhances the performance of an item of interest. A broad...
In the first article in this series entitled How to Put It All Together - Guide to Organizing a Successful PEI Program, I provided an overview of the necessary Management Systems for a successful program to achieve excellence in pressure equipment...
In the first article in this series entitled How to Put It All Together - Guide to Organizing a Successful PEI Program, (1) I provided an overview of the necessary Management Systems (MS) for a successful program to achieve excellence in pressure...
In the first article entitled How to Put It All Together - Guide to Organizing a Successful PEI Program in the current series of articles that I am writing, I provided an overview of the necessary Management Systems (MS) for a successful program to...
