PipeDN

Nominal Pipe Size Calculator

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

Accurate pipe sizing and max flow limits in seconds. The definitive nominal diameter calculator for all industry professionals. 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.
