A expert, please help me check the steam flow rate
Thread Content
The steam main operates at 0.4 MPa and 180°C. I would like to use a temporary pipeline for this purpose; the back pressure is at atmospheric level. Without considering the flow rates specified in the standards, can a 2-inch pipe meet the demand for 5 tons of steam? I seek guidance from experts.
This. . . The guy upstairs said it’s not enough
The guy downstairs said enough. . . This should be it. . .
For DN50 open-type systems, the recommended safe flow rate is 0.8–1.0, with a flow volume of 5–7 tons; for closed-type systems, the value is higher. What do you plan to use it for? Install heating? The supervisor should find a reliable welder, otherwise there will be sand holes in a few days
It’s not flowing again; the flow rate is at normal pressure, and the key factor is still the 2-inch pipe, which is sufficient
What is the unit for flow rate? I’m using this gas for protecting the furnace tubes during the heating process before starting up the furnace. The manufacturer recommends using 5 tons of steam; I’m wondering if a 2-inch pipe can handle that amount of steam. If not, I’ll use a 3-inch pipe instead

The manufacturer’s plan for furnace drying should be quite thorough, and the representative on site has experience with such processes. The manufacturer recommended a flow rate of 5 tons, which should be sufficient for material protection; however, it’s necessary to verify what quality of steam is being used, as the specific heat values can vary. I guess that in most cases during the furnace drying process, 5 tons isn’t necessary – the amount of steam available is sufficient. But where does the steam go after passing through the furnace tubes? Should we argue with the sky, with water, with the air? :Lol, when you come to Zhejiang, I’ll treat you to squirrel fish
