Gasify is the all-in-one gas engineering tool built for installers, service engineers, and commissioning professionals. Whether you’re sizing pipework, verifying existing installations, calculating gas rates, or working out purge volumes, Gasify helps you work faster, smarter, and with confidence.

? Key Features

Pipe Sizing Calculator
Visually build pipe layouts with fittings and appliances, then calculate the correct pipe sizes using hybrid sizing logic. Supports:

Copper pipework from 15 mm to 35 mm

Steel pipework from ½" to 1¼"
Includes accurate pressure drop analysis across each section.

Verify Existing Pipework
Input real-world pipe sizes and fittings to check if an installation is undersized. Supports:

Copper pipework from 15 mm to 35 mm

Steel pipework from ½" to 1¼"
Gasify highlights any appliance path that exceeds the 1 mbar pressure drop limit and gives you a detailed breakdown per route.

Purge Volume Calculator
Quickly calculate purge volumes by entering meter type, pipe lengths, sizes, and materials. Supports copper, steel, and PE pipes, with grouped totals per material. Import saved pipe layouts for fast and accurate entry.

Gas Rate Calculation (Metric & Imperial)
Switch between metric and imperial modes with built-in timers. Automatically calculate gas rates, gross and net heat input, and check results against 5% and 10% tolerance thresholds. Save results for multiple appliances.

Professional PDF Exports
Generate branded reports for pipe sizing and gas rates. Include your company name, engineer info, job details, and appliance data. Share or print PDFs straight from your device.

Save & Load Jobs and Systems
Save individual appliances or complete pipe systems with job names and timestamps. Reload saved jobs to continue work, verify results, or create updated reports.
