How to correctly size a drain pocket for a steam line
Properly sizing drain pockets is critical to ensure efficient condensate removal and prevent issues such as water hammer or pipeline corrosion in steam systems. The table below provides guidelines for selecting the appropriate size of drain pockets based on pipe and drain pocket dimensiions.
| D | d1 | d2 |
|---|---|---|
| Up to 100 mm | d1=D | Minimum d2 = 100mm |
| 125-200 mm | d1=100mm | Minimum d2 = 150mm |
| 250 mm and above | d1>D/2 | Minimum d2 = D |
