Maintenance & Reliability

Reliable machines require competent maintenance skills

SKF Reliability Maintenance Institute: Patrick, G. B.

A proactive approach will provide significant returns through better utilization of existing staff

Retrofitting multijack tensioners on a combustion gas turbine generator

Saudi Arabian Oil Co.: Al-Mohssen, H.

Consider this technology for difficult bolting applications

Fieldbus improves control and asset management

Emerson Process Management: Smart, J. D.

Substantial benefits are realized from increased diagnostics and process data

HP Reliability: Consider overspeed protection retrofits

Hydrocarbon Processing Staff: Bloch, Heinz P.

The overwhelming majority of small turbine overspeed trip devices are mechanical; they incorporate a spring-activated trip bolt that moves out and contacts a trip lever whenever a pres..

Case history 6: Keep those bolts tight

Consulting Engineer: Sofronas, A.

It’s important to keep operating loads less than the bolt preload

HP Reliability: Consider disc pumps where impeller pumps fail

Hydrocarbon Processing Staff: Bloch, Heinz P.

Until recently, finding a suitable pump was difficult for plants pumping viscous fluids or fluids that undergo viscosity change. Here, using conventional centrifugal pumps may lead to poor performance..

HP Reliability: Strategic mechanical seal partnerships

Hydrocarbon Processing Staff: Bloch, Heinz P.

Not all mechanical seal supplier agreements benefit both parties equally. We have recently seen some rather one-sided ones. At a recent users conference, the suggestion that the "partner" should discl..
