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?
