Big size pipe in Pipe Rack
Big size pipe in Pipe Rack
(OP)
Hi all,
Is there any guideline or practices for what is the bigger size pipe that can be use in pipe racks?
in this presentation recommend 30" water lines:

RE: Big size pipe in Pipe Rack
That is a very, very simplified training presentation on "how to design pipe racks" ...
It uses - as an example for training - a single large water and a handful of smaller pipes, and presents a series of useful "thumbrules" ....
Why do you think pipe racks are limited to 10, 20, 30, 40, 60, or 72 inch diameter? They are limited to "how to route, run, and support pipes" so "they go here to there and don't break and can be built"?

You asked:

The answer to your specific question regarding pipe size limitation on Pipe Racks is 'No' there is no limit.
However there is always good engineering practices and judgement that needs to be observed to insure a proper design.
Example:
>Pipe of any size with a thin wall may need saddles or cradle shaped reinforcement so the wall does not collapse
>Large diameter pipe lines should be evaluated for proper lateral restraint on projects located in earth quake prone areas and on Offshore rigs
Sometimes its possible to do all the right things and still get bad results

At that point, the very large, very heavy pipes are run separately from pipe racks at (or under) ground level, and the smaller pipes are run up in the pipe rack. Water cooling pipes are usually the first to be run underground, since the energy to pump cooling water up high in large pipes on expensive pipe structural supports and piers is very, very high.

A rule of thumb when deciding the elevation difference between piperack levels is 3 times the largest Nominal Pipe Size (NPS) of pipe that runs in the rack. The stringer levels, the steel beams between columns that support the pipes leaving the piperack, are set mid-way between the main beam levels or 1-1/2 times the largest NPS pipe. This allows that the largest pipe can be rolled out of the rack with a fitting –to-fitting LR 90 degree elbow and a 45 degree elbow and that a pipe size of half the largest NPS pipe can use tow fitting –to-fitting LR 90 degree elbows to leave the rack.
For a 30-Inch pipe, the elevation difference between main beam levels will be 2286 mm. Given that there has to be space to work within the piperacks, 1220 mm between levels is probably the minimum necessary.
