I have a project that involves a long steam pipe run from a power plant to an off site steam host. The distance is about 1/2 mile and the current concept is to use a pipe rack. This is multiple steam lines and different pressures. The steam is high pressure with superheat (not saturated "wet" steam). We would normally slope steam lines in the direction of flow at 1/8" per foot (1%) but for a long horizontal distance this becomes difficult, especially on a rack.
I have read some old posts on this topic that essentially concluded with pipe racks may not be the best solution for long steam lines requiring slope. I agree with this but there are some good reasons a rack is desired in this case. What we have currently designed is mostly a flat (no slope) line with drip pots every 300' or so and at every major change in direction. My opinion is that there are as many opinions on how best to handle this situation as there are engineers with opinions. What I am looking for are some actual project examples so I can make a judgement on "industry practice".
Does anyone have actual project examples that I could follow up on to help me get an idea of what is being done out there in the real world?
