2.0 INFORMATION TO STEAM FITTER
1. Assuming availability of 30 psi supply steam pressure immediately to the appliance, then
pipe sizes of ½" or 3/4" or 1" will deliver respectively 90, 165 or 385 lbs. of steam per
hour to the appliance Heat Exchanger. 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 will be 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.
