Just my three cents.

RE: piping sloping
In chemical plants we use the same slope when we can. You would like to have the piping be as "self draining" as it can be when out-of-service, especially in systems that are transporting reactive chemicals. You would like to have these lines drain back to the vessels and where that is not possible, provide a "drip leg" with a small bore block valve to drain the leg manually. The idea is to keep the lines clear when the pumps stop so that you will not have the reactions continuing in the piping (and perhaps plugging them). To some degree, we would use the same principles in refinery piping. If the line is heat traced, we would like it to be self draining to be sure the lines are clear in case the steam or electric power are temporarily lost and the piping temperature cools.
RE: piping sloping
Some lines that I have worked on have been required to have a specified minimum slope at all times, hot or cold. When that's the case, the installed slope on some legs may need greater than the minimum slope so you still have the required slope when the line is hot.

For our lines going to sump (mostly drains, drip pans, etc), we use 1:100 slope. I think I have also seen 1:125.

RE: piping sloping
is it true if you slope "your" lines too much you can leave those little doggies high and dry!!

RE: piping sloping
Agreed, the major concerns with oil travel in any ammonia system is to keep it's affect's to a min. in the evaporator, condenser, discharge lines and suction lines. Some systems drain and remove collected oil using dog legs, others use seperaters with floats and hot gas to return it to the compressor. The evaporators and recievers in many of these systems incorporate dog legs to seperate and remove oil from these areas.
