Production choke/Gas lift
Choke type
DCV-C400
Choke size & rating
4″ ASME Class 2.500
Actuation
Hydraulic Modulating
Existing problem
A: Short meantime between failure due to extreme cavitation
B: Eroded internals and bodies
Causes of problem
A: High delta P (up to 300 Bar ) with seawater
B: Cavitation
Solutions
A: Dux has designed also based on CFD simulations a special internal with a better
flow pattern to reduce cavitation and to avoid erosion due to cavitation
B: Being used on several locations amount of stops reduced and life time is much
longer
Results
Less downtime
Next case
