HP Reliability: Recognizing advantageous API seal flush plans
A feature article in the May 2008 issue of HP dealt with sealing issues of interest to industry.1 It explained the energy conservation and environmental benefits described in the API literature. The p..
HP Reliability: Consider oil mist for positive-displacement blowers
       Positive-displacement blowers (Fig. 1) are often used to move air ranging in pressures from slightly negative to about 15 psig (~ 1 bar) positive. These rotary-lobe machines..
HP Reliability: Remembering Flixboro: part 2
Last month's column attempted to make the point that reliability professionals must search for answers to questions as to why equipment failed. It related when one of six cyclohexane oxidation reactor..
Remembering Flixboro: part 1
At a recent gathering of over 500 reliability professionals in Texas, we invited questions from the audience. I was asked what I thought of installing flexible piping (or connectors) on centrifugal pu..
