AFT: An International Leader in Pipe Flow Modeling Software

Since 1994, AFT has been a recognized international leader in pipe flow modeling software. We work with 40 international distribution partners and serve over 80 countries. Our portfolio of industries and projects is impressive with proven success in helping engineers simulate, analyze and build anything from simple to highly complex systems.

Throughout our history, AFT has worked hand-in-hand with some of the world’s best and brilliant engineers. In 1994, Trey Walters, P.E. laid a solid foundation that AFT has been able to build on. The software tools he initially developed have continuously increased in ability and have allowed engineers to do more with their designs and stretch their projects beyond what they thought was possible.

AFT has taken technology that once had to be outsourced to experts and created tools that an everyday engineer can use to accomplish the same goals. 

AFT has had the honor of being a part of innovative projects and providing challenging solutions. With the knowledge that the projects our software is used for are highly proprietary, we take great pride in showcasing a database of case studies which high-profile industries around the globe have shared so we can give others a glimpse into how industries utilize our technology. But we know this is only the tip of the iceberg.

When engineers have issues they have never seen before, AFT has the answer. There is not much we haven’t seen and haven’t been able to fix. That’s because AFT engineers go the extra mile in all directions to ensure efficiency, safety and accuracy.

We have helped engineers design and troubleshoot an array of systems used within the power, aerospace, water/wastewater, chemical, and of course oil & gas industries, just to name a few. Engineers in any industry can use our software for systems ranging from simple models, to highly intense waterhammer/surge or pulsation mitigation.

AFT software tools exist to help engineers in two primary ways:

  1. Ensure accurate and safe designs to prevent issues and build efficiently.
  2. Quickly troubleshoot problems so systems can get back to production as quickly and cost-efficiently as possible.

AFT looks forward to many more years of helping engineers who help us as much as we help them. Through the years, AFT has befriended engineers who tell us their stores and give us honest feedback on what they need. These conversations do not fall on deaf ears. In our future travels, we hope to meet whoever is reading this so you too can share your stories and challenge us to continue to be an innovative organization.

Thank you for your friendships, your partnerships, and cheers to many more years of innovative engineering.
