HP Reliability: Publish or perish – a reminder to industry
A number of useful textbooks dealing with machinery reliability and dozens of technical papers dealing with related subjects owe their existence to an interesting policy. Twenty-one years ago, one of ..
HP Reliability: Closed-loop oil mist systems are a viable lubrication option
Although plantwide, centralized oil mist systems have served industry well since the early 1960s, closed-loop oil mist systems have made major inroads only in this decade. Environmentally-acceptable a..
HP Reliability: Reliability growth models for process plants
Failure data are used to build simple log-log plots for predicting future failures and identifying if failure trends are improving or deteriorating. On the Crow/ AMSAA plot (Fig. 1), stable processes ..
HP Reliability: How installation and operation influence MTBF
Mean-time-between and mean-time-to-failure (MTBF and MTTF) can differ for the same equipment. The differences are often attributable to quality of installation and grade of operation. This situation i..
HP Reliability: What to do with reliability indices
This issue is often raised, or even debated. A simple explanation would be that reliability data can be converted into uncomplicated, figure-of-merit performance indices. Consider these indices as coa..
