Maintenance & Reliability
Case 31: The analytical modeling niche
A simple model can greatly expand your equipment knowledge
Use the system approach to spare parts management
It yields substantially better results than the commonly used item method
Pitfalls of operating pumps at part load
The risk in terms of reduced reliability and safety is not worth it
HP Reliability: How to find a job and keep it . . .
That was the heading on a periodical that I always enjoy reading. It made the point that "Many people lose their jobs not because of a lack of technical skill, but because they lack the ability to com..
Troubleshooting repetitive failure of a CO2 ompressor rotor
Here's how the plant personnel overcame the unique and complex problem of residual magnetism
HP Reliability: Consider bidirectional flow devices for mechanical seals
Many dual mechanical seals found in centrifugal pumps use either pumping rings or pumping screws to move barrier fluid. Typical flowrates achieved with pumping rings are extremely low, with most of th..
Case 30: One cause of a pump not pumping
A stronger pump can block out the weaker one
Update design and maintenance methods for refractory systems
Better design methods and repair efforts reduce failure of these systems
Improve asset performance management
