Liquiducts pipe doesn't have a rate limit on steam at least. You can have the steam from dozens of boilers combine into one liquiduct pipe section and all be available for output.
The numbers of concern are what is available at inputs and outputs.
For input there are 2 options unpowered - meaning the machine or source fills the attached pipe
Or powered - the pipe is wretched to output mode and red stone signal applied, the pipe pulls liquid from the source.
For output you just have then pipe connection. The largest consumer you can test with is a steam turbine which only accepts 160 steam through a liquiduct input. This likely a limit imposed by the turbine because the liquiduct carriesn much more.
In practice 4 output mode liquiducts can pull all 720 steam from a hp boiler. Deductively this is likely 100 steam per powered output and an additional 80 from the passive output of the boiler itself to each connection.
