pipe flow engineering software

We specialise in the marketing and support of pipe flow simulation software. Whether it’s the steady-state flow of  liquids, gases, slurries or 2-phase liquid/gas flow - or unsteady flow  resulting in water hammer - we have state-of-the-art software to assist engineers in their design and simulation of fluid flow in pipe networks. 




Design, simulate and analyse the steady-state flow of liquids, gases, slurries and 2-phase liquid/gases in complex pipe networks. Simulate unsteady conditions, both long term changes and short-term water hammer. 


GASWorkS™ and GASCalc™  are two programs specifically for the design of natural and other gas reticulation systems.

GASWORKS - Natural Gas Reticulation LEARN MORE & EVALUATE
GASCALC - Gas Flow Formulas


Simulate water hammer in linear pipe systems and networks. View the transient pressures in real time. Model pump start and stop, valve position change, non-return valves and many other types of boundary elements.


Design and select orifice plates, venturis, flow measuring devices, control valves, relief valves and rupture plates to international standards for single- and
two-phase flows.


AFT software simulates liquid and gas flows in complex pipe systems and liquid flow water hammer. AFT software provides an easy-to-use  interface, proven calculation methods and an excellent graphing capability for the presentation of results.



software capabilities

Pipe systems may contain virtually any type of line equipment – pumps, fans, control valves, orifice plates, heat exchanges - and any equipment item for which a pressure drop characteristic is known. Fluid types may be Newtonian, non-Newtonian, 2-phase liquid/gas and particulate (settling) slurries.

As well as steady-state flow, our software can simulate unsteady liquid flow conditions, be they flow and pressure variations over the long term such as changing fluid levels in a tank, pumps and fans starting and stopping or valves modulating or short-term changes resulting in water hammer.

Specific equipment items, such as orifice plates, control valves and relief valves can be sized independently from manufacturers’ own design methods.

We back-up our software with more than 30 years of experience in support and training and can also provide an in-house bureau service for the design of pipe flow systems using our software.



We supply permanent and lease licenses for our software and provide training and on-going support.

Support is not limited to simply key-stroke advice; we can assist in you in selecting software for your particular application or guide you through the design process of a particular project. Email us your design and we can check your calculation, even display the model and discuss via our video chat software. 

We keep you updated with the latest release of the software via our annually renewable Maintenance, Update and Support agreement.

We also provide a bureau service for the design of fluid flow systems using our software. We can perform the complete design on a consultancy basis or build your model for handover for you to perform future simulations.

We have developed one-, two- and three-day training courses for most of our software.



CPEng, Principal

Graeme Ashford, Director of Accutech, is a professional engineer (Charterd with the Institute of Engineers, Australia), has a masters degree in civil engineering hydraulics and has lectured in fluid mechanics at degree level in Australia and England. He has worked in many areas related to fluid mechanics:- in hydraulic laboratories in England and Canada; on water and wastewater, process and fixed fire protection projects; and through Accutech on literally hundreds of pumping and pipe flow designs.

Accutech is based in Perth, Western Australia, and has been marketing and supporting engineering software since 1986. We are sole Australian distributors for a number of New Zealand, UK and US based developers. Our software is in use in many of Australia's major mining, process, engineering and petrochemical industries.

We are a Registered Propriety Limited company in Australia.

We have supplied software to International Companies such as Shell, Woodside Energy, Alcoa World Alumina, BP Oil, Fluor, BHP, Calibre, Hatch, Rio Tinto, Worley Parsons and many more.
