I have some questions about slopes
Thread Content
I read in chemical engineering design manuals that pipes should have a slope, with this slope generally running in the direction of fluid flow. The manuals then provide specific slope values for certain types of pipes (such as steam and steam condensate). I also saw in the standards that pipes throughout the entire system should have a slope, and that this slope should not be less than 0.02. . . . ”Are these two combined? Are only pipes for overall steam, steam condensate, and the like required to have a slope? Are pipes for steam or something like that also needed? Additionally, I hope the expert can explain which pipes it is best to give a slope to during piping, even if there is no requirement specified in the PID.
Steam and water pipelines both require a hydrophobic slope
1. Gas medium, but liquid will precipitate; this liquid is useless and harmful, so a slope is required to collect it and drain it at a lower point: for example, flare lines, steam lines, etc
2. Liquid pipelines require a slope to facilitate the flow of liquid within them or to remove any residual waste； Or the medium may be toxic, etc., to facilitate subsequent cleaning and disposal ； Or gravity flow. 3. High-end property owners require the pipe ducts to have a slope, so all pipes are sloped (which results in higher costs). 4. Low-end property owners have lower requirements; they only need pipes for specific media. The first two types I mentioned require slopes
