HP Reliability: Consider single-point responsibility for compressors
Equipment purchasers are always interested in meeting the cost and schedule targets for projects. However, there could be conflicting goals when purchasing compressor drivers and/or auxiliaries from v..
HP Reliability: Best practices when trim-cutting closed-pump impellers
Experienced reliability professionals will implement least-risk solutions whenever possible. The following example relates to impeller trimming to reduce the diameter of a fixed-speed centrifugal pump..
HP Engineering Case Histories: Case 77: Random deck vibration with beats
When something vibrates, it is usually in a predictable manner. Motors, pumps, compressors, turbines and centrifuges all vibrate when they are out of balance. Vibration analysis can help predict the s..
GE to buy Cameron’s reciprocating compression division for $550 million
The division provides reciprocating compression equipment and aftermarket parts and services for oil and gas production, gas processing, gas distribution and independent power industries.
Update on lubrication systems
Several case histories illustrate the pros and cons for maintaining rotating equipment under various plant conditions.Example 1In late May 2013, a US oil-mist provider in one of the Great Lakes states..
Control moisture in ‘wetted’ rotating equipment
In turbomachinery, water is one of the most deleterious contaminants. Left unchecked, moisture can severely reduce the service life expectancy of oil-wetted rotating and reciprocating components by as..
Improve quality of lubricating fluids via filtration
Micro-sized dust particles, along with water, can ruin the best lubricating fluids. Contamination of lubricating fluids can occur due to the byproducts of combustion, metal wear, oxidation and more. T..
Wide design margins do not improve engineering
Engineers use design and safety factors in sizing and specifying instrumentation or major process equipment, such as pumps, valves and compressors. Design factors are applied to cover the uncertainty ..
HP Reliability: Was that a failure or ‘just a repair’?
Purists among reliability professionals are sometimes concerned about the accuracy of the measurement of the mean-time-between-failure (MTBF) of an asset. There are many ways to conduct this failure f..
