Maintenance & Reliability
Mitigate corrosion in your crude unit
Real-time analyzers can provide improved monitoring of chloride levels and enable better corrosion control practices
Case history 58: Piston pin plug wear
A wear analysis can help when failure data are meager
Calculating the temperature distribution in horizontal vessel saddle supports
The heat-transfer theory of cooling fins is applied
Spiral-wound or kammprofile gaskets?
There appears to be a shift toward the latter, but the choice isn’t always clear. Here’s where best to apply each type.
HP Reliability: Eccentric reducers and straight runs of pipe at pump suction
Questions relating to proper reducer application in centrifugal pump suction lines date back many decades. Until his death (at age 84, in 1995), world-renowned pump expert Igor Karassik frequently cor..
