pipe sizing

[chitel]

Please, can anyone assist me with an Excel spreadsheet template for pipe sizing as per ASME B31.3

Thanks

B31.3 really has no "sizing" criteria. You can make the diameter as large or as small as you like.

chitel...

Big Inch is correct.....

Pipe size is based on process flow demands, and/or to minimize pressure drop in a long system. ASME B31.1 and B31.3 only provide rules for pipe materials, wall thickness, valve selection, pipe supports etc..etc

The ASME B31.1/B31.3 codes assure system structural integrity.

Rules for pipe sizing are commonly developed on a project-by-project basis.

For most liquids, a velocity of 6-10 ft/second is suitable.... but pump suctions should be sized for 2-5 ft/second. There are exceptions..

More information can be found in "The Piping Handbook" by Nayyar and in the Crane, "Flow of Fluids" Manual #410.

Is this your first time sizing piping ?
