Thanks for the answers,
API RP 14E have information like Crane but the difference that API rP 14E works with Qg gas flow rate expressed at 14.7 psig and 60° F; not sure why, but I guess that if I work with one of this expressions at the last I will have to convert this Qg to operation...
I've read the article, but I don't find the answer it's refered more for liquids.
I want to design a nitrogen pipeline (-astm a312_), also I've read Crane the chapter about principles of compressible flow and said that the maximum possible velocity in the pipe is sonic velocity.
So in order...
I'm designing a Nitrogen distribution system that is going to fill a pressure tank (500 Psig), so I need to know the recommended/allowed velocities that I should consider through the steel pipe and if you can refer a Standard or book that talks about it.
Thanks in advance.

Flowrate no determined yet, I've just taken these project, I have tank's plans, the transient study where I find the flowrate on water pipeline, but not sure yet the N2 flowrate but I'm thinking to calculate from the tank volume, and when the system is activated, means when it is a critical...
Thanks for all the answers , @BigInch as you said certainly it's closer to an auxiliary system, a N2 supply for the surge system (surge tank). Apologyze, may my english wasn't clear enough, it's why I use the word pipeline, but in fact it's going to be a small supply station, closer to the...
I thought that as a b31.8 is for Gas transmysion and distribution piping system could be suitable for my purpouse, but I read in the code that :"802.12 This code does not apply to: (d) piping in oil refineries ... , industrial plants, or MINES ."
Attaching again the picture.
Thanks!
Sorry, If Im not explained as well, the pipeline that I want to design is the Nitrogen one, not the water pipeline.
I'm attaching a sketch, about my 2 enquiries, first Which code about Nitrogen pipeline design is proper to use? and 2nd if you know some NFPA or safety code about distances...
In order to avoid water hammer effect on a water pipeline a customer installed 3 surge tanks that will be filled by nitrogen, it's located in a mine over a 4500 meters above sea level.
There are 2 questions, I have to design the pipelines that goes through each nitrogen group of cylinders to...
