Steam - Condensate Pipe Lines - Capacities (kW)
Maximum capacities for condensate pipe lines in kW steam consumption.
The table below can be used to determine the sizes of a condensate pipe line where the heat consumption in kW is known.
| Nominal pipe size | Steam Consumption (kW) | |||||
|---|---|---|---|---|---|---|
| Wet main | Dry main with gradient | Vented Pipes | ||||
| in | mm | 1 in 200 ft | 1 in 600 ft | Vertical | ||
| 1/2 | 15 | 30 | 10 | 6 | 10 | 12 |
| 3/4 | 20 | 70 | 30 | 18 | 30 | 47 |
