Maintenance & Reliability
Diamond-coated seals extend pump life
Although problem-free pump operation is the primary goal of all pump operators, achieving that goal is not a simple matter. The key components of a pump - mechanical seals, impellers, couplings, roller bearings and housings – are all subject to wear.
Case 57: Troubleshooting the cause of sudden impacts
Finding the cause can be elusive but calculations help
HP Reliability: Not ready for 29-year-old pump packing
In 2009 we were informed about “a nuclear plant that was never commissioned after its original construction. This plant has been sitting idle for 29 years and is only now starting up.” The o..
Furnace tubes-enhancing safety and efficiency with infrared thermography
Thermal imaging offers advantages over thermocouples
Troubleshooting waste-heat boiler poor heat transfer
Analytical results showed that potash leached from the catalyst, refractory powder, corrosion products and, to a lesser extent, catalyst fines resulted in tube fouling
