How is the diameter of the common pipelines in fine chemical plants determined? For example, how are the diameters of the utility pipes in the central corridor of a workshop calculated? What about the diameters of pipes for steam, circulating water, chilled brine, heat transfer oil, etc.? Most of these are used to heat or cool the jacket or coils of reaction vessels
The determination of this pipe diameter is based on the requirements of the installation or the user, as well as the volume of air required in emergency situations. For example, if the compressed air consumption by the installation is 500 Nm3/h (corresponding to a pipe diameter of DN40), and the consumption in emergency situations or under maximum load is 800 Nm3/h (corresponding to a pipe diameter of DN50), then DN50 should be chosen as the pipe diameter for this pipeline.
How are 500 m3/h and 800 m3/h calculated?
I’m just giving an example; the numbers are not real. For the pipe diameter, you can consult a design institute for design work
