What size should the drain valve for a 1.0MPA steam DN80 pipe be?

The drain pipe for DN80 pipelines is DN20 or DN25; the size of the steam trap matches that of the drain pipe. If the water rejection capacity is not particularly high, choose DN20, as this is also the size of the vent pipe.

The reply on the second floor was very detailed; after considering everything, it’s better to choose DN25

For the calculation of water flow rate while driving and during normal use, reference can be made to hg20570

The amount of condensate in the steam trap has little to do with the pipes
