Let you Google "practical pipe sizing guidelines". You'll get a lot of references. The first one, and supposedly the most relevant one, is Rules of Thumb: Flow Parameters. The author, Stephen Hall, is a member here.
The RoT that caught my eye is this one - "A rule of thumb that incorporates pipe size is to choose liquid lines to handle a velocity of 1.5 +d/10 where ādā is the pipe diameter, inches. This gives 1.6 m/s for 1-inch and 2.5 m/s for 10-inch piping, and about 20 kPa/100 m pressure drop. Similarly, gas lines can be sized for 20d m/s and steam lines 35 m/s (maximum)."
By the way, I love your username!

I recommend finding the Handbook of Offshore Engineering by Chakrabarti. ISBN is 9780080443812. This goes into developing design basis. Chapter 11 (in the second volume) gives sizing criteria for gas and oil lines. It also provides real examples from selected offshore projects.

Thank you for your dedication! I guess I'll have to look it up.
and my user name is my life motto! I'm glad you like it.

Thank you Pilesar! I'll look it up too!
