The slope issue of pipelines for loading refined oil by rail
Thread Content
I’d like to ask the experts here for some advice: The railway loading platform is approximately 720 meters long, and 60 gasoline loading nozzles are installed; the main gasoline pipeline has a diameter of DN500. I would like to ask everyone: is there any requirement for a slope when laying the DN500 gasoline main pipe, which is about 720 meters in length? Can it be made with a 0 slope? Thank you all again~~
If following the petrochemical route, the slope should be at least 0.003.
Personally, I think it’s not possible to follow the petrochemical industry’s standards; otherwise, there would be a height difference of 2.1 meters over just 700 meters. Since the SH3107 specifications don’t mention any requirements regarding slope, I’m not sure whether it’s possible to achieve a zero-slope design. Ah
SH3107 does not specify any slope requirements for pipeline layout; it depends on which standard you follow. What is the terrain like in the factory? Is there any natural slope?
I made a mistake earlier; if following the petrochemical route, the slope should be at least 0.002, with a height difference of 1.4 meters every 700 meters
First of all, thank you for your reply. This project is a refined oil depot project, with the stored gasoline and diesel products being shipped out via rail. The ground should be level to prevent things such as vehicle rollback.
0.002 is the requirement for pipes throughout the entire plant, while 0.003 is the requirement for pipes that remain within a specific area. Since your pipe does not fall into either category, there should be no particular requirements regarding its slope.
Okay, I can’t find any regulations that clearly specify the requirements for pipelines in railway loading and unloading areas either, so for now I’m setting the slope to 0. Thank you so much!
