nstallation
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.
Installation And Service Connections
WARNING
Plumbing connections must comply with applicable sanitary, safety, and plumbing codes.
Similarly, in 1” pipe size, a standard 90 elbow, and Angle Valve and a Globe Valve are equivalent to 2.2 feet, 12 feet and
23 feet respectively of straight pipe.
NOTICE
In 3/4” pipe size, that a Standard 90 Elbow, an Angle Valve and a Globe Valve are equivalent to 1.8 feet, 10 feet and
18 feet respectively of straight pipe.
Total of above = 20 + 2.2 + 3 + 2.2 + 17 + 23 + 10 + 2.2 + 79.6 feet. Since each 10 foot is equivalent to 1 psi pressure
loss, 79.6 feet is equivalent to approximately 32 psi from an original boiler supply of 40 psi.
It is suggested that, wherever possible, the steam supply line to the appliance be a separate line from the steam source.
If the appliance must be supplied from a line supplying other appliances, the pipe sizes and pressure will have to be
verified. Further, during idle periods, when the steam in the supply line is not in use, water will form from condensed
steam in the supply line and it is advisable to prevent water pockets from forming in the steam line and impeding the
steam flow when it is required. Therefore, contrive to have the steam supply line level or run slightly downwards towards
the appliance. Install a Ball Float Trap near the appliance to drain out water (condensed steam) from the line to assure
clean dry steam to the appliance.
