Pipe Capacity?

[Rubzensky]

I'd assume that each of pipe has a maximum capacity so that you can't just use one pipe for 400 oil rigs. How many pumps does it take to be at maximum capacity for a pipe? Or is this going to be simple and I only need to use one pipe to feed everything (the Dream)

Well, why take a chance?

EDIT: I apparently don't know as much about fluid flow as I thought.

So singular small pumps always slow you down to the minimum speed of 30/s?
If I build small pumps in line, they do exactly as much as 1 pump?
Is this real life?

Pipes have a maximum of ~180 fluids / sec. Tested with tanks and offshore pump lowest time I can get to fill 2000 water units is ~11.11sec using one pipe.

With 2 input for tanks the maximum flow is ~ 277 fluids/sec.

Each oil refinery take 2 crude oil/sec. So in optimal situation one pipe can deserve 90 oil refinery.

It is best to use underground pipes as much as possible for they keep the same pressure at each end. And if memory serves me right, keeping max pressure in the lines require one pump every 10-15 pipes (been a long time since I played vanilla).

Thanks for all the replies :) This has been very helpful!

At a certain point, it'll just be more convenient to barrel the stuff or and send it via train. just make sure the place you end up dumping the empty barrels is the same network you create them or you can end up in barrelpocalypse.

I can attest to this! I actually route my barrel trains to a depot especially to ensure they have a full load of empties before every oil pickup.

I can't wait till the tanker comes in .15

Same here, I could never get it so that it only take the used barrels instead of new ones. Thou there has been a mod that adds a tanker car for some time and I love using it.

I don't use mods, simply because I have yet to launch a rocket and I don't want to break my achievements.

Before I started routing my trains to an empty-barrel-dispenser, I would have 1/2 of my train as empties and 1/2 as fulls. I use 1-4-0 trains, and the rear two wagons carry the full barrels.

I would have one dedicated train per oil outpost, so I end up with 4 or 5 (or even more) trains that just do oil. I would set up wait conditions so that the train would not leave the oil outpost until empties=0 and fulls=800, then at the consumer (Plastic, blue circuits, etc) I would set a wait condition of empties=800 and fulls=0.

It was ineffecient as the train could be waiting quite a long time at the outpost if the wells were depleted. I eventually modified the wait condition on boths end to also include a "or 30 seconds passed" condition, which is a bit better. But now those trains constantly drive around, even if the oil they are carrying isn't needed at all.

If I remove the 30 second wait at the consumer and only leave it at the oil outpost, then the other trains would jam up behind the first. Clearly I need to continue design work on my oil system.

[!?!]

All you need to do is wire the inserter that takes empty barrels out of the train to only take 50-100 per station.
1 train can just go to all the oil fields that way.

Fluid trains will simplify this tho.

My system isn't designed for this. I deliver a full load of 800 barrels on each trip, or 30 seconds worth of oil, whichever is faster.

As long as 800 empties are queued waiting for pickup, the train never sits for a full 30 seconds. Now I need a way to determine if the train should even bother going to the empty-barrel-pickup station.

[!?!]

Yeah I've seen people making a train wait until it's full which literally takes an hour on depleted oil field and then they make 1 train for each field and just have a barrelpocalypse on the refinery.
Completely unnecessary. Oil transportation doesn't need much.

I agree. On one partiular depeleted oil field, I have the train wait 30 seconds, and it will pickup 155 barrels in that 30 seconds. So, the combination of speed modules, beacons and quantity of oil wells at that singular site will produce 155 barrels of oil every 70-80 seconds (30 seconds wait at each end and travel time). If the train gets blocked and takes the long way, I have seen it gather 170-180 barrels.

155 barrels of oil delievered every 70-80 seconds is much better (IMHO) than waiting 5+ minutes to deliver the full 800 barrel cargo. Ultimately its the same amount of oil over a similiar amount of time. The only trade off is burning a bit more coal to run the train to get the oil delivered in smaller batches.

The refinery never runs out with the 30 second wait, but does run out otherwise.

Either way, its way more complex than it needs to be. I want my tanker wagon so bad!

EDIT

Now that I think about it, I actually wonder why the refinery runs out on the larger batch of oil. Its a larger batch and should last a comparable amount of time to the smaller batch being delievered more frequently. I'm not particularly inclined to test it as I am building a much larger plastic facility and it won't matter then anyway.

It is curious though.
