  • Thicknesses and dimensions of 3” – 36” ductile iron pipe adhere to ANSI/AWWA C151/A21.51. Weights may vary due to slight variations in bell weights. Thickness and diameter in inches.
  •  *Calculated weight, including bell, of pipe rounded off to nearest 5 lbs.
  • Table above based on ANSI/AWWA C150/A21.50 and includes 0.08” service allowance and casting tolerance by size. Dimensions in inches.
  • **Design determined by internal water pressure measured in psi. Thicknesses rated to 150 psi working pressure plus
    100 psi surge pressure per AWWA C150. Calculations reflect minimum yield strength of 42,000 psi and 2.0 safety
    factor times the sum of the working pressure and surge pressure.
