Propylene is Cost Effective
Fuel Fuel Oxygen Labor Total
Cost Cost Cost Cost
Acetylene $1.50 + $3.36 + $25.20 = $30.06
Propylene $1.26 + $3.08 + $22.80 = $27.14
Propane $0.46 + $4.95 + $31.92 = $37.33
Natural Gas $0.00 + $4.84 + $31.92 = $36.76
Calculations based on costs per 100 feet of 1 inch plate.
Labor estimate is based on typical cutting speed for each gas.
