All,
API 14 E is developed for erosional velocity prediction for tubing/pipeline but there exists some uncertainty in calculating erosional limits.
Is there any procedure to determine actual erosional velocity as a function of flow rate, temperature, pressure & gas-liquid ratio and material properties??
Further more "Prosper" calculate erosional limits based on empirical constant "C" which is dependent upon produced fluid characteristics & target material properties (hardness, ductility & density).For sand free production: Is there any set of rules to select C values for different metallurgy (stainless steel, carbon steel, chromium alloy, etc) & downhole environment???
