GASCalc

GASCalc™ is a legacy Windows-based calculation suite covering the full spectrum of natural gas pipeline engineering — from pipe flow and meter sizing to regulator, relief valve, and gas property analysis.

Gas Properties

Calculate the fundamental gas composition properties — compressibility, heating value, viscosity, enthalpy, and hydrate formation — that drive every downstream pipeline calculation.
Hydraulics

Determine pipe flow and pressure drop using a variety of industry-standard equations across fully turbulent, partially turbulent, and low-to-medium pressure flow regimes
Meters

Size and validate every major gas measurement technology, from orifice and turbine to ultrasonic and cone, with a built-in MatchMaker to find the right fit for any flow condition
Miscellaneous

Estimate gas volume released from a damaged pipeline segment for rapid incident documentation and emergency response.
Regulator & Meter Systems

Model complete single- and two-stage pressure control stations and meters — from individual device sizing to full supply, intermediate, and vent stack piping analysis
Valves and Fittings

Size regulators and relief valves against manufacturer-specific equations from Fisher, American Meter, ISA S75.01, API 520, and more.
