Experts in Pipe Water Hammer and Surge


Choosing to utilize a software tool means you are willing to invest in a long-term solution to the analysis and maintenance of your piping system.

Applied Flow Technology (AFT) has developed a unique waterhammer software which takes the place of hand calculations. With precision analysis, a powerful interface, and user-friendly features, AFT Impulse is a tool you should look into. 

How does it work? AFT Impulse incorporates a steady-state solver providing seamless transfer of initial conditions to the transient analysis. Steady-state solutions are determined using a modified Newton-Raphson matrix iteration. The traditional Method of Characteristics is used to solve the transient mass and momentum equations of pipe flow.

Waterhammer and cavitation can be a big project to tackle and will take time from your workforce. Time and manpower you might not have available.

Transient Monitoring Systems

For users of positive displacement (PD) or PD-style pumps, the issues of addressing damaging pulsations caused by the stroke of the pump are all too common and unavoidable. These pulsations will often violently rattle or shake piping, causing noise, premature wear and potentially a complete break in the pipe itself or damage to valuable components in the flow path downstream of the pump.

Many times, these anomalies go undetected due to insufficient recordings. Therefore plant operators do not know they have dangerous abnormalities until it is too late.

Blacoh’s patented SurgeWave™ Transient Monitoring System makes it possible for a user to capture these pressure fluctuations, address the pressures loads and protect their pipeline systems.
