Case 39: Vibration failure of a heat exchanger tube
Flow-induced vibration damage is a commom problem
Case 38: Extruder wear prediction
An analysis can help avoid wear problems before they occur
Case 37: Can you tell me how long it will last?
Troubleshooting differs from design
Case 36: Pipe bowing stresses due to thermal differences
A pipe partially filled with a hot cycling fluid can cause weld failures
Case 35: Technical checklists
Our memories are not always adequate
Case 34: Hydrotesting or pneumatic testing?
There is a big difference in safety between the two
Case 33: Vessels in high-cycle service
Weld failures can be due to manufacturing defects
Case 32: Piping flexibility concerns
Thermal upsets can cause pump problems due to piping loads
Case 31: The analytical modeling niche
A simple model can greatly expand your equipment knowledge
Case 30: One cause of a pump not pumping
A stronger pump can block out the weaker one
