Cavitation elimination in a long vertical pipeline


The project under investigation is a light crude oil transportation system, located in China. The pipeline (constructed from DN700/DN600) is over 3km in length, ending with a vertical drop of 130m to the tank.

In this system a primary concern was the likelihood of cavitation in the vertical section. PIPENET was used to estimate the steady state pressure distribution, estimate the cavity volume in the vertical pipes, and assess proposed measures for eliminating any cavity thereby reducing vibration and noise.
