When steam turbines trip the turbine stop valve closes rapidly which generates a steam hammer transient wave. This wave can cause significant transient loads on piping. The de facto method of predicting these loads is the Goodling Method from the 1980s. AFT’s newest software product AFT xStream revealed that the Goodling Method was not always […]

Attendees can participate in technical committees to lend their experience and knowledge to the standards writing process. Network with your industry counterparts, attend educational […]
Check valves are designed to protect equipment from sustained reverse flow, but a closing check valve introduces a lurking risk of secondary surge. This webinar will outline considerations for check valve selection such as the type of check valve, the system potential for reverse flow, and the deceleration of the system's fluid. AFT will take […]
Join instructor Bob Jennings discusses pump curves and how to optimize pumps to their system to achieve energy savings.

When building models in AFT Arrow, you may notice the Cv/Kv loss models in valves require extra input, known as xT. This does not show up in valve models for incompressible flow, which most people are more comfortable with. ANSI/ISA-75.01.01-2012 defines xT and special considerations for compressible flow, and gives methods for control valve sizing. […]
