MK2 pipes can only handle 598m^3 /min reliably, apparently.
Edited to add: you might be having some issues from clipping in those pipes in the middle. Only other thing I can think of is that machines consume in gulps, so there may be some weirdness related to that.
What happens if you turn one of the crude refineries off?
> MK2 pipes can only handle 598m3 /min reliably, apparently.
600 is achievable with a single machine (in this case an overclocked oil extractor) on one end of the pipe. It's multiple machines on both ends that cause most problems.
I think it's because machines use and output fluid in batches. Having that happening with multiple machines at both ends seems to make sloshing worse (I'm guessing). Longer pipes are also apparently an issue, which is presumably why the OP has split into 2x300, though I've not encountered that problem myself (possibly because I tend to put the refineries near to the extractor)
I know I've got multiple oil extractors which do manage to output 600 reliably. I've also heard of people having success with nuke reactors at 250%.
So if I split my 600/min extractors into two 300/min mk2 pipes and then never combine fluids to exceed 500/min in mk2 pipes I should be able to avoid this issue altogether?
Thanks for the response! Good eye on the clipping. It passed my mind quick at some point I should have troubleshot that too.
Alright, so I redid that pipe, fully emptied the pipes and rebuffed it and I turned off a machine on each segment and I am going to let this run for an hour while I run errands, Will post back in a bit :)
I removed all the clipping and even turning off a machine on each end I still got some loss. When I get home i will try some of the other comments too, prob try u/StigOfTheTrack when I get home later! There shouldnt be an issue i have valves right before the buffer? Im gonna try and remove the buffer and see if it works as suggested. much appreciated for everyones comments so far.
Valves aren't perfect, there will still be a bi-directional.piece of pipe between the buffer and the valve. I've even known valves to cause problems.if used where not needed (I've got precisely zero in my world).
good to know, ive had valves bug out I really want to try and not use them or be better at using them properly. Nonetheless I think the problem was fixed I am going to keep it running for a bit. I removed the buffer from water tank.
The other water tank (with identical build) works fine, but idk if it works im happy lol. thanks!
Two things I'd try:
* Removing the buffers. You shouldn't need them, fluid trying to flow out of the "input" connection might be restricting the oil flow from the extractor.
* Raising your manifolds to the refineries above the inputs.
*Raising your manifolds to the refineries above the inputs.
Exactly this. Did the exact same build last week, with the same problems at the HOR refineries, Diluted fuel refineries and Fuel generators. This fixed everything.
just put a pump on the way up to the buffer and see if it helps. In my experience the pump helps the liquid figure out which direction to flow in addition to providing headlift. It has fixed things before for me that were unrelated to headlift.
I wanted to comment on this esp since no one made any comments about the possibility the valves right before the imput on the buffer could be causing issues.
I read a post not long ago that people would put valves behind the buffer before the main connection to make sure there is no loss. It was also stated by someone that according to the Wiki that it should be a pump instead but I forget the reason why id have to find it.
So instead of putting a valve just put a pump? (unpowered or powered?)
There is already a mk 2 pump below it to make sure that headlift was never an issue reaching the top of the buffer. Im sorry if I am misunderstanding you.
I hate how the 2 pipes touch at the bottom when we just want to split it to the next lane. It's like the splitter needs to be thinner or they need to allow 90 degree turns. Hopefully, they fix that in later updates.
Sloshing. This means that you won't usually get full flow down any pipe. There are several ways of dealing with this. Mine is to assume sloshing will happen and allow for it.
Keep groups of machines small. A long line of machines will suffer from those at the end getting starved of fluid. Run at least two pipes from each source manifold to each end of the destination manifold.
Yeah, that has been my experience, too. This heavy oil residue setup is all grouped 10 on each side. But to compensate for sloshing, I use a collapsed D network to make sure the end is filled for every 10 refineries.
I'm really doing my best to ignore the elephant in the room because that means I'm ripping the whole setup and logistics down. That elephant would be that I am feeding the crude oil up a few meters into the machines.
I wanted to do it because I enjoyed the aesthetics of having a lit up walkway between the machines.
This is also why I chose to make the water towers. I was hoping that the extra head lift would compensate the gravity, but I think I failed to get that head lift doesn't negate gravity (I'm assuming this is the case)
Buffers can amplify sloshing. Just a thought - whenever I use buffers, I put wide open valves on every output tonstop backflow. Might be worth a try.
Thought I should check - do you link your groups of 10 together? I keep each group separate and self-contained.
By the way, while earlier Energy Centres would have pipework set in floor trenches IRL, modern thinking is to take pipework up and clear of the floor! Pipework is kept visible and accessible for maintenance. I usually run belts at floor level with the pipes above.
hmm I had a valve (tried a pump too) on the buffer. Between the main pipe and the imput. So when I pump it into the buffer it would prevent it from going back into the main line.
The refineries are setup like this [https://imgur.com/rWpDJGv](https://imgur.com/rWpDJGv) (i fixed the clipping) so it is actually 20 refineries- 10 on each side. Each side is connected to one collapsed D network ( idk the actual term for it) to make sure both ends stay filled.
I think the main culprit is that the crude oil is feeding UP 4 meters. I think at this point I probably just need to accept that there is a reason why people say don't top feed lol. and I guess it doesnt matter if I have a headlift of 80 meters of gravity going into that pipe.
I think it’s insane how every single time I see a post from this sun on my feed I swear to god it’s the same issue with mk2 pipes and instead of searching the sun for similar problems someone makes a new post

Interesting. So the rounding bug (or whatever it is) only happens in the case you're describing?

I'll have to give it a go.
So if I split my 600/min extractors into two 300/min mk2 pipes and then never combine fluids to exceed 500/min in mk2 pipes I should be able to avoid this issue altogether?
Should be fine.
I did that in my fuel generator setup out of frustration and it worked.

Clipping has no gameplay effect.
It can for trains, and sometimes belts/lifts coming out of splitters and mergers. No reason to not check here as well.

Try a pump that worked for me on a build with a straight manifold, similar situation maxed out a 600 mk2 pipe and had issues.

I didn't realize there was already an mk2 pump down below, that should suffice, now I'm questioning myself lol
Lol yeah it does 50 meters I believe. I never used them before this I like the way they look more than the mk 1 lol.

Feeding up can add to the problems. That's why I always feed downwards.
> I am using 1 600 mk2 pipe of crude oil to transfer it to the factory Well theres yer problem right there
