About this app

PipeCalc is a powerful offline pipe fitting database, unit converter, and pressure drop calculator designed for engineers, plumbers, pipefitters, and technicians working with piping systems.

FEATURES
PIPE FITTING DATABASE
Browse and search a comprehensive library of standard pipe fittings with over 1,700 entries. Filter by type (pipe, flange, elbow, joint), material (Carbon Steel, Stainless Steel 304/316, Alloy Steel, HDPE), nominal diameter (15 mm to 600 mm), pressure class (Class 150, 300, 600), and schedule (SCH10 through SCH160). Tap any fitting to view detailed specifications including dimensions, weight, design pressure, temperature ratings, bolt hole patterns, and more.

UNIT CONVERTER
Convert between Metric and Imperial units across five categories with a clean, intuitive interface:
• Length: mm, cm, m, in, ft
• Pressure: PSI, bar, kPa, MPa
• Temperature: °C, °F, K
• Mass: kg, g, lb, oz
• Volume: m³, L, ft³, gal

Swap button for instant reverse conversions.

PRESSURE DROP CALCULATOR
Calculate pressure drop in piping systems using the Darcy-Weisbach equation. Input flow rate, pipe dimensions, fluid properties, and fitting losses. Supports multiple fitting types and schedules.

OFFLINE-FIRST
All data and calculations run locally on your device using IndexedDB. No internet connection required. Your data never leaves your device.

AUTOMATIC THEME
The app automatically follows your device's light or dark mode setting for comfortable use in any environment.
