~ Valve
– 50/50 preference ball vs. plug – Good pm program increases life
~ Decoking Valves
– Check Water Quality – Rebuild Options
~ Drill water Piping/Bypass valves
– Erosion/Corrosion Issues – Bypass valve reliability – Instrument air quality
~ Drum Cracking
– Quench procedure – Good operation and design are key – Plan for inspection and repair – Effected by cycle time – Reduced quench times – Safety issues (Fires, etc.)
~ Hot Drums
– Quenching time/rates – Blowouts – Causes – Caution with using closed type drill guides
~ Drill stem
– Put odd section on the top – Life limited by cave ins
~ Drill Stem Issues
– Failure Mechanisms – Corrosion – Overtorquing – Outside Contractors – Trained – Right Equipment – Increased Safety
~ Heater Tube
– Failure mechanisms (many) – Becht has method for checking carburization of the tube
~ Maze Issues
– Water quality – Fines management – Pump reliability – Type of pump – submerged vs. vertical
~ Maze Pumps
– Submersible vs. vertical – Water handling needs to be properly designed & operated
~ Furnace Changed Pumps
– Need a good warm up procedure – Be careful cleaning strainers
~ Coke Handling
– Want to avoid cutting rates – FELS vs Bridge Crane – Cranes need proper design
~ Elevators
– Freight vs. Passenger – One facility has no issues
~ PM of emergency equipment
– Fall arrestors – EBV values
