New at sizing steam lines
(OP)
I am on my first steam involved project. I am to take steam from my header and drop the temp and pressure.
The header is at 117 psi, 353 deg F, 60,000 #/hr. My equipment needs 5 psi, 248 deg F, 4800 #/hr.
The total feed pipe run will be around 50 feet.
The header is superheated and the equipment feed is a saturated mixture.
Everything online wants to know a velocity, which I do not know.
How should I go about picking a pipe diameter?

Since you are a newcomer in the matter of steam, I would suggest to you start visiting this site: http://w
Good luck!

I have a few guides for selecting pipe sizes. One guide uses a pipe velocity of 100 ft/s for saturated steam pipes larger than 8" and pressures under 25 psig. The same guide recommends a velocity of 160 ft/s for saturated steam over 25 psig and pipe sizes over 8". For smaller sizes, it recommends lower velocities.
Of course this is just a guide for selecting economic pipe sizes. Everyone has slightly different ideas on what are good velocities to use. You should also still check pressure losses and such.
