INFORMATION TO STEAM FITTER
Each cooking compartment requires approximately 2.5 BHP (86.25 lbs. of steam per hour
minimum) to operate satisfactorily.
Assuming availability of 30 psi supply steam pressure immediately to the appliance, then pipe
sizes of ½" or ¾" or 1" will deliver respectively 90, 165, or 385 lbs. of steam per hour to the
appliance. From the foregoing to use ½" pipe line would most likely prove inadequate.
An extremely important consideration is the pressure drop that will occur through the steam
supply line from its point of origin to the appliance. The greater the length of piping and number
of valves and elbows, the greater the pressure losses.
Consider a pressure drop of 1 (one) psi for each straight length of pipe equivalent to 120
diameters of that pipe. Thus, a 1" pipe having a straight length of 120" (10 feet) is equivalent to
120 diameters of that pipe and will have a pressure loss of 1 psi through that pipe.
