Steam traps for draining should be located
- on horizontal pipes - every 30 - 50 m (100 - 150 ft)
- in front of pressure reducing valves to avoid damaging the equipment
- in front of control valves to avoid damaging the equipment
- in front of normally closed valves to avoid building up condensate that may damage the system when accelerated
- at the bottom of vertical lines
- at the end of the steam line
Recommended Drip Leg Dimensions
|Main Diameter||Pocket Diameter||Pocket Depth|
Example - Drip Leg Dimensions
The recommended drip leg dimension for a 80 mm (3 in) steam pipe is 80 mm (3 in). The pocket depth should be 700 mm (28 in).
Steam & condensate systems- properties, capacities, pipe sizing, systems configuration and more.
Huge amounts of condensate are generated when cold steam pipes are heated up must be drained from the pipes.
When cold steam pipes are heated up they generate huge amounts of condensate that must be drained away from the pipe through steam traps - in Imperial Units.
Friction or major resistance in condensate pipe lines.
Flow and pressure loss in condensate return lines - SI Units.
High temperatures and danger of impeller cavitation is the major challenge for condensate pumping in steam systems.
Heat loss from steam pipes generates condensate which must be drained from the system - imperial units.
Heat loss from steam pipes generates condensate which must be drained from the system.
Steam is a compressible gas where the capacity of a pipe line depends on the size of the pipe and the steam pressure.
