I'm using a pump module, which moves 1000mB/t and thus should be saturating the pipes.
as far as i could understand the mechanics of pipe, the actual fluid per pipe is just 1000mb, when pumped it will move, and behind will be outer 1k, so it dont have more than this at continuous work, to resolve some of it, you would need to pump from outer sides, so intead of just 1k, if you use 3 pumps module would be 3k per work, however, since the pipe use the next and previous pipe capacity, it will have a space of 3 pipes until another full one move. The best result would be to store on a digital tank and the tank feed the machines. just a noobish guess.
GregoriusT : i would guess a machine that emulete the remaining function of the metalformer, the extrauding thing. i would like an eletric hammer so i can stop wasting materials on that, or even better, the projects to be used on workbenchs.
