Installation distance of the steam trap
Thread Content
The steam pipeline is 500 meters in length, with a DN100 diameter. The operating pressure is 14 kilograms, and the operating temperature is 280°C. Which specification should the steam traps have, and at what interval should they be installed? The pipeline is laid above the ground
If it is used within a factory premises, I recommend using a mechanical type with a diameter of DN20 or DN25. The principle for setting up hydrophobic devices is to place them at the lower points along the flow direction whenever there is a change in elevation; if it’s a straight line, they are usually installed every 200 meters.
It is recommended to use inverted barrel steam traps equipped with built-in check valves. A steam trap should be installed every 50 meters, at the lowest point of each rising and descending pipe, as well as at the end of the pipes. The steam trap station should be equipped with a water collection tank; otherwise, no matter how large the pipe diameter is, it will be ineffective. With a water collection tank in place, a DN25 condensate pipe can be connected to the side. The steam traps should be placed as close as possible to the steam collection tank, and inverted barrel steam traps of type DT580 with a DN15 diameter are suitable for this purpose.

Steam traps should be installed at the lowest points of the pipes and at their ends, especially at the ends of pipelines that are used intermittently.
Are the sizes of steam trap valves used in steam pipes of different specifications also different? Where can this be found in relevant standards?
This has nothing to do with the pipe diameter; it depends on the amount of condensate produced. If it’s superheated steam, the amount of condensate is very small, so a smaller diameter pipe is sufficient. If it’s saturated steam, the length required is greater, so a larger diameter pipe is needed. This requires calculation, but often it is done based on experience.
Generally, DN25 steam traps are used, one every 50 meters.
