How to size a steam trap
WebMar 20, 2024 · Selecting a Float and Thermostatic Steam Trap. Our example requires 2000 PPH in a low pressure 10 PSIG system. The 1.5 safety factor gives us a rated capacity of 3000 PPH. We use a differential of ½ PSIG. This differential is selected because the pressure in the shell may drop as low as “0” as discussed above and in the earlier Steam ... WebTo determine the correct orifice size, the following information is required: 58 5 psig pressure drop across the heater P2 = 10 psig Steam trap Back pressure: 1/2 psig for each foot of rise P3 = 5 psig + 3 psig [6 ft rise x 0.5 psig] FIGURE 1. Shown here is the setup and data for Process Example No. 1: Unit heater Application.

Webconditions to help in sizing steam traps for draining Drip Leg/Drip Point locations. At first glance it would seem that creating a Drip Leg is simply a matter of connecting piping or equipment to a correctly sized steam trap. But, an analysis of the varying conditions inside a steam system reveals that the location and sizing
WebFor example, a steam unit heater with a 1-in. condensate outlet would require 1-in. or larger piping/tubing from the unit heater to the same connection size on the steam trap. Piping Connection Downstream of Steam Trap: The pipe/tube diameter downstream of the discharge connection of the steam trap should be expanded. WebEquation 1 can be used to calculate the amount of flash steam ( i.e., the percentage of condensate that flashes to steam) for the steam traps in Figure 10. At 145 psig, QSh = 336.0 Btu/lb; at 0 psig, QSl = 180.2 Btu/lb and QLl = 970.3 Btu/lb; and at 44 psig, QSl = 260.8 Btu/lb and QLl = 916.8 Btu/lb.
