Underground Fuel / Compressed Air Piping
Underground Fuel / Compressed Air Piping
(OP)
Hi All,
We are currently working on an infrastructure project and we have encountered clashes when undertaking BIM modelling.
With various services running parallel to each other (Wet & dry utilities) it is evident that these will cross at some point.
My question is for compressed air pipework (pressure approx 12 Bar G) would there be any issue with elevation changes over a distance of approx 7km i.e. 45's / 90'Deg bends to offset other services.
My next question is the same however relates to fuel pipelines, petrol, diesel and waste fuel.
I'm not overly concerned with air locking etc on the Compressed air line however I am worried about the fuel and the potential for sludge build up on the diesel / waste fuel lines and concerned regarding air locking.
Thanks in advance for any help.

RE: Underground Fuel / Compressed Air Piping
If you are concerned with solids deposition in oil pipelines, the answer is to keep the pipeline velocity high.

"waste fuel" - What on earth is that?
"BIM modeling" ?? don't assume we know or use initials the same way you do.
If you've got "sludge" in your diesel lines then you shouldn't be pumping it. Remove the dirt first.
Otherwise as bimr says you need to keep velocities above the 1-2m/sec range to sweep any debris along.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
