Drain in steam pipes is a must i.e. sloped pipes (very commun mistake not to) . The slope recommended by Spirax Sarco is ½ inch in 10 Ft of pipe (1/250) . with drain points between 100 and 200 ft.
But is has to have them, for operation and for shout off and start.

Hi,
Well it is not common to see Sloping steam line. May be it would have been
done in order to catch condensate. You can do away with slope if this is the
reason by intoducing drip legs and steam traps at low points. The drip legs
location should be at lowest point in that pocket and nos depend upon the
capacity required to remove the valuable condesate which in turn depends upon
primirarily on pressue (i.e L.P, M.P., H.P. and HHP).
Sloping lines have thier own problem so try not to see them on p&id`s untill and unless really warranted.
As to ur last qs I feel it is process designer responsibility to indicate any such reqt.
best regards
Hi all,
The Slope in steam lines is different (exp 0.5%, 1%, 2% <---- as I see in some
projects).
But Generally who should decide about the amount of slope (piping or process designer) and how the suffiecient slope is calculated? does any criteria exist to select the piping slope or related to experience?
