PipeSizer: Diameter Selector

PipeSizer helps piping and process engineers screen pipe diameters quickly using flow rate, pipe material, schedule, liner, and traceable velocity ranges. Enter your design conditions and PipeSizer ranks candidate nominal pipe sizes by calculated velocity. The result highlights the best candidate, effective internal diameter, velocity status, and nearby alternatives so you can compare options without rebuilding a spreadsheet. KEY FEATURES • Rank candidate pipe diameters from your flow rate • Compare velocity against traceable recommended ranges • Support for clean water, process fluids, slurry, and utility lines • Carbon steel, stainless steel, HDPE, and common schedules or DR values • Optional liner allowance • SI and Imperial units • Save and reopen sizing results • Share results using the iOS share sheet • Send selected pipe data to Pump Mate • English, Spanish, French, and Portuguese • Fully functional offline PipeSizer is free and designed for fast engineering screening in the office or field. ENGINEERING NOTICE PipeSizer is a screening aid. Verify final selections against project criteria, applicable codes, manufacturer data, and a qualified engineering review.
