GASCalc™ Is our popular suite of analytical tools. It was specifically developed to aid in the design, analysis, and operation of natural gas distribution, gathering, transmission, plant, and fuel piping systems. It includes routines for calculating a variety of stress, flow, and pressure values for devices and pipe associated with virtually any piping application that transports or delivers natural gas. Its wide range of features provide the ability to investigate piping problems from the well head to the burner tip. Some of its features include...

Pipe Flow & Pressure Values - More than twenty-five different industry related pipe flow equations are supported for sizing and calculating pressure loss across pipe and fittings. Also included are routines for calculating blowdown and venting values, purging and clearing values, fill time, pipe volume, and service line sizing.

Regulator & Relief Valve Values - Support is provided for calculating pressures and flows through a variety of regulator and relief valve devices. The routines allow analysis of single devices or devices configured in various “station” arrangements. Devices from multiple manufacturers can be compared side-by-side, or in combination in a station configuration. Support is provided for both table and equation based performance data. These routines are perfect for performing annual relief valve capacity checks.

Stress Values - Routines are included for calculating a variety of pipe stress values including bending stress on pipe spans, thermal expansion and contraction, hoop stress, stress caused by roadway and railway crossings, steel and plastic pipe design formulas, total combined stress, stress from in-service pipe lowering, and segment MAOP values.

Meter Sizing - Support is provided for calculating pressure and flows through a variety of meter types - including orifice, diaphragm, rotary, turbine, ultrasonic, and cone meters. Other measurement related calculation routines are also provided, allowing quick calculation of volumes at different operating pressures, base conditions, or atmospheric pressure conditions.

Gas Properties - Support is provided for calculating various physical and thermodynamic properties associated with a gas composition. Routines are included for calculating compressibility, sonic velocity, specific gravity, heating value (calorific value), viscosity, specific heat, entropy, enthalpy, hydrate formation, atmospheric pressure, average pressure and temperature, and pressure, temperature, and volume values at varying conditions.

Miscellaneous & Utility Routines - A number of routines are provided for calculating a variety of miscellaneous and utility values. Routines include calculation of fuel interchangibility, velocity, hydraulic diameter, flow limiting devices, compressor values, well flow values, line heater sizing, Reynolds Number, anode life, remaining strength of corroded pipe segment, container volume, energy and dimensional units conversion, heat loss and gain across devices and piping, and value interpolation and extrapolation. One convenient routine estimates gas loss from a punctured or severed line.

Application Programming Interface - Many of the calculation routines are also available through the GASCalc Application Programing Interface (API). The API allows access to the supported calculation routines by way of programmatic function calls, allowing the User to create and access the calculation routines through their own interface or a custom developed user interface. The API is available at an additional charge. More Information...
