Abstract: |
All the choke valves in Tarim Oilfield KL2 gas field come from famous companies around the world. Typical failure cases, such as circular groove on the corbula, beehive holes, axial trench, impact hollow, internal surface and plunger end erosion, plunger fracture and crack, are explained using erosion mechanism, fluid mechanics etc. , which reveals some failure causes of choke valves, evaluates the usability of different valves and provides theory basis for valve’ corrective selection and design.
