PipeSizer: Diameter Selector

Screen pipe diameters quickly using traceable velocity ranges, practical rankings, and SI or Imperial units—even when you are offline.

PipeSizer is a fast, practical pipe-diameter screening tool for engineers and field technicians. Enter one or more flow rates, choose the fluid, pipe material, schedule or dimension ratio, and optional liner, then compare ranked candidate sizes against a traceable velocity range.

KEY FEATURES • Ranked candidate pipe sizes with velocity and effective internal diameter • Multiple flow cases with a clearly identified governing condition • Carbon steel, stainless steel, and HDPE sizing options • Optional liner allowance • Traceable velocity ranges with source information • Saved results for later review • Shareable result summaries • Direct handoff to Pump Mate for detailed hydraulic analysis • SI and imperial units • English, Spanish, French, and Portuguese • Works offline with no account required

PipeSizer is free, contains no advertising, and has no in-app purchases.

ENGINEERING NOTICE PipeSizer is intended for preliminary engineering screening. Final pipe selections must be verified against project specifications, applicable codes and standards, manufacturer data, operating conditions, and qualified engineering judgment.
