Suction headers sizing (Ammonia)

[xixxi]

Hey!
I am just curious, do we have any official requirements for velocity of ammonia in suction headers? I didn't find it in ASHRAE.

Thanks!

Xixxi,
Maybe you should download this Danfoss Coolselector 2 programme.
It can help select valves, pipesizing etc.
