The Pipe Sizer is a productivity app developed by Nopparat Katkhaw. The app is a simplest and quickest pipe sizing. Perform quick calculation and accurate results. Use the finger slide for quick calculations. Shows Steel, PVC, HDPE, and PPR pipe sizes for any schedule or class. Compatible with IP, SI and JP units. We would very much like your feedback!

Pipe Sizer is an interactive log-log pipe sizing chart based on the Hazen-Williams equation, made for engineers and technicians who size water piping: plumbing, condenser water and chilled water systems. Tap the chart to read values instantly • Flow, friction loss and velocity on the nearest pipe size • Shows whether the point is inside the design zone (too slow, too fast, or over the friction limit) • Double-tap to fix a flow rate, then slide one finger to compare pipe sizes at that flow • Pinch with two fingers to zoom and pan Pipe catalogues • PVC to Thai standard TIS 17-2532 (classes 5, 8.5, 13.5) and PVC Sch40/80 (ASTM D1785) • PPR, HDPE (PN4–PN25), steel Sch40/60/80, GSP (BS 1387), CPVC and PB • Inside diameters are calculated from each standard's wall thickness Fits your project • Open system (C = 100) and closed system (C = 140), or enter your own C factor • ASHRAE STYLE and CARRIER STYLE (Carrier open-piping chart values for steel pipe) • Flow in gpm, L/min or m³/h; friction loss in m/100m, ft/100ft, Pa/m or kPa/m • Adjustable design zone: minimum and maximum velocity, small-pipe limit and maximum friction loss • Dark mode, automatic or by choice • Thai, English and more than 30 other languages Compressed air and steam (new in 1.4.0) • Compressed air: sizing chart by working pressure, separate main-header and branch limits; steel, galvanized, copper and PPR; L/s, m³/min, m³/h, CFM • Saturated steam: sizing chart by pressure, with saturation temperature and the heat carried; kg/h, lb/h, t/h • Darcy-Weisbach with the Colebrook friction factor, per ASHRAE Fundamentals Pipe insulation (new in 1.4.0) • Chilled water: anti-condensation thickness from water and air temperatures and humidity (ASHRAE dew point) • Steam: thickness that keeps the outer surface below a set limit, with the heat loss • Check an existing thickness · 7 insulation materials · jacket choice Works offline.

Verdict
The clearest difference is price: Pipe Sizer at $2.99 against PipeSizer's $4.99. PipeSizer's advantage is iOS requirement (12.0 vs 16.4). On in-app purchases there is nothing between them.
