PipeDN vs PipeFall

Need to determine the pipe size for a new industrial project? Want to check the maximum recommended flow rate for an existing fluid line? PipeDN is the ultimate pocket tool for industry professionals. Quickly find the ideal Nominal Diameter (DN) or maximum operating flow rate using velocity limits based on practical, field-tested engineering standards. Beyond delivering the exact requirement, the app generates a smart reference table of neighboring commercial pipe sizes (larger and smaller). This gives you the comprehensive technical data to choose the best design alternative for your facility. Highlighted Features: • Calculation Modules: "Find Ideal DN" and "Find Max Flow". • Native support for multiple pipe materials and schedules. • Professional PDF Reports: Export a detailed calculation memory directly to PDF. Include specific pipeline TAGs for customized, ready-to-archive engineering results. • Custom Units: Fully adapt pressure, temperature, flow rate, and diameter unit sets to match your region's standard. • Embedded Physical Tables: The Steam module features built-in thermodynamic properties for precise dynamic density tracking. Supported Fluids & Applications: • Water & Condensate: Treated Water, Condensate (Pump Discharge, Pump Suction, Steam Trap Return). • Steam: Advanced sizing targeting Saturated Steam and Superheated Steam lines. • Process Gases: Combustion Air, Flammable & Non-Flammable Gases, N₂, O₂, LPG. • Compressed Air: Limits tailored for Main Lines and Secondary Branches. • Vacuum Systems (Manifolds, Separators, Blowers). • Pulp & Paper Industry Niche: Exclusive calculation module for Cellulose Pulp responding to various consistency levels (up to 6%), as well as comprehensive chemical recovery liquors (Black Liquor in 4 concentrations, Green Liquor, Lime Mud, Dregs, Filtrate, Alkalis, and Tall Oil Soap). • Common Chemicals: Sodium Hydroxide, Sulphuric Acid, Antifoams, and Lubricating Oils.

Tired of flipping through code books on the job just to size a drain? PipeFall turns fixture counts and pipe runs into code-referenced sizes in seconds. Here's how it works: pick your code, add your fixtures or enter your run, and PipeFall returns the minimum pipe size, the required slope, and a pass-or-fail check against the exact table it used. Done. No accounts. No uploads. No tracking. Everything happens on your iPhone. Whether you're roughing in a bathroom, sizing a building drain, or checking a trap arm before the inspector arrives, PipeFall is built to be the fastest way to get the number right the first time. It covers drainage fixture unit sizing, water supply sizing with Hunter's curve, drainage slope and fall in every common format, vent and trap arm checks, pipe offsets and rolling offsets, pipe volume and weight, and thermal expansion. Every table is based on the 2021 International Plumbing Code, so the sizes match what the inspector checks against. You can even set your iPhone on the pipe and use it as a slope level, then send the reading straight into the calculator. Every result is referenced to the code table behind it, so you can always show your work. Save jobs, group your calculations, and export a clean PDF for the file or the client. PipeFall runs 100% offline — no data collection, no ads, no sign-in. 3-day free trial, then $1.99/week. Cancel anytime.
