Just as a good medical doctor is expected to have wide knowledge on modern treatment options, we would expect reliability professionals to be equally informed on technology advances. There are numerou..

Optimize your compressor maintenance program

Geitner, F. K., Consultant

One deviation alone might not be enough to bring on a compressor failure, but, when several more deviations combine, the failure risk is known to increase exponentially.

Digital is the solution for modern compressor protection

Stachel, K., Locken, T., Hoerbiger Compression Technology

Compared to traditional analog communications technologies, digital systems cost less, offer greater flexibility, and are more reliable thanks to built-in self-checking systems and resistance to interference.

HP Reliability: Four-stage, low-flow process centrifugal compressor can fill important industry gaps

Bloch, Heinz P., Hydrocarbon Processing Staff

In the 1970s and 1980s, multistage centrifugal compressors in the 3,000 acfm (about 5,000m3/hr) and lower flow ranges were largely confined to instrument and plant air duties. Three stages with interc..

HP Engineering Case Histories: Case 74: How to determine impact forces when troubleshooting

Sofronas, A., Consulting Engineer

When troubleshooting failures, it is not unusual for the metallurgical report to indicate that the failure was the result of an impact type of force. The investigator who receives this information mus..
