N2 - The corrosion behavior of API 5L X-70 pipe steel was studied in a jet impingement chamber, which simulated the effect of flow rate and contact angle on pipe accessories. Experiments were carried out in sour brine with kerosene and corrosion rates were determined by linear polarization resistance. Corrosion products were characterized by scanning electron microscopy and X-ray diffraction to identify crystalline phases on surface. Parameters under study included flow rate (1.05, 2.36 m/s) and contact angles (30°, 60°, 90°). Highest flow rates were associated to top corrosion rates due to corrosion product detachment on which prevailed that of oxide type, whilst moderate flow rate and static conditions led to a larger number of phases on which sulfides predominated over oxides.
