  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

  4. Example of Film Boiling • http://www.spaceflight.esa.int/users/fluids/TT_boiling.htm

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

  6. Largest Possible Pipe 32”

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

  8. Equations Used • Find h_bar • Using… • With…

  9. Solution

  10. Spreadsheet

  11. Conclusion & Recommendations • 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

  12. THANK YOU
