1. Pipe Quenching Heat Transfer Project Aaron Rowe Kenneth Johnson

2. Introduction 1200+ °F pipe coming out of Annealing Oven present hazard to handlers Pacific States Cast Iron Pipe Co. has challenged us to come up with a table to show how long it would take and how much water would be needed to cool the pipe to 650 °F

3. Boiling Curve

5. Pipe Range from 6.5” to 32” O.D. This effects time and water flow needed Different Size Pipe

6. Largest Possible Pipe 32”

7. PSCIPCO will design system to expose pipe to flow for specified time Oven Exit

8. Equations Used Find h_bar Using… With…

9. Solution

10. Spreadsheet

11. The maximum amount of water needed and the time the pipe must be exposed is: 27 gallons per minute for 3 min. 20 sec. When running smaller pipe, operator may choose to speed up conveyor belt or decrease water flow Conclusion & Recommendations
