Re: Steam Piping Sizing

Thomas:

Economics, general facility practice, and even noise can and should be considered in sizing steam lines. Also, you didn't mention if the steam is saturated or superheated. However, assuming it is saturated, the rule of thumb is 6,000 to 10,000 fpm for sizing steam lines. If you have a copy of Crane Technical Paper 410, "Flow of Fluids through valves, fittings, and pipe", it has nomographs and equations. If you don't have a copy, I strongly suggest buying one - last time I checked they are about $75.

[PipingDesign] Steam Piping Sizing

Ladies and Gents:

would you kindly help with a steam pipe sizing problem? i generally work with process fluids, and i'm not sure how to handle steam.

we have a small device that demands between 100 and 2000 lb/hour of 160 PSIG steam. what issues should i consider when sizing the piping to this device?

thank you all for your help.
