As part of several years research activity with erosion in chokes, Norsk Hydro ASA has developed a model to estimate erosion and lifetime of chokes by incorporating erosion models into particulate flow models. This model has been verified with the results from flow and erosion testing of two different types of chokes, Needle&Seat and External Sleeve. The erosion tests with both the modified Needle&Seat...
This paper describes predictions of erosion depth in pressure reduction valves (chokes) caused by solids and large amounts of droplets.Solid and droplet erosion data for WC (tungsten carbide) with 6% Co and 6% Ni and polycrystalline diamond (PCD) have been transformed into correlations. These correlations have been coupled with particulated fluid flow models to determine the erosion depth due to solids...
