Getting there is graph the fun! - Multi-Scenario Pump vs. System Curves

Pump vs. system curves provide an intuitive, graphic way to understand how a pump interacts with a piping system. These can be useful during pump sizing, but can also be informative when your pump must function in a variety of operating conditions. Understanding how changes to your pump or system affect your operating point can be invalua...

Where to Start with Pump Startups

Any time a rapid transient occurs in a piping system, there is a chance for unexpected surge to impact the system. Though system shutdowns account for many surge events, pump startups can cause water hammer as well. For this blog I am going to cover the basics of setting up pump and valve transients for the startup case in AFT Impulse 7 , as well a...

Looking to relieve pressure? Let's talk about Relief Valves in AFT Impulse.

In any complex piping system, one of the most serious scenarios considered during a safety or HAZOP study is over-pressurization. If the pressure in the system reaches a high enough pressure, rupture can occur, leading to expensive repairs, significant system downtime, and even loss of life. In most cases, proper use of relief valves can mitigate o...
