Vent at the high point of the steam pipeline
Thread Content
The pressure in the steam pipelines inside the plant is 1.4 MPa, and the length of these pipelines is 120 meters. It is necessary to install exhaust valves at several points; the design team has suggested placing one such valve every 18 meters on the drawings. Is that not a bit too frequent?
One should consider how many high points along this pipeline require venting, rather than the distance between them. I don’t think the design will include vent valves at intervals of 18 meters; it’s probably just a coincidence regarding that distance
If they are at the same height, there’s no need for so many high points, right?
Under normal circumstances, it’s not necessary; having a low point in the higher areas is sufficient
If the steam is in continuous operation, there is basically no need to drain it after it is introduced
It mainly comes down to the high and low points; the exhaust valve is installed at the highest point, right, rather than based on some interval
