Note, 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.
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.
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.
