Corrosion tests were carried out on C-steel (API 5L X70) and 13Cr steel (AISI 420) materials in a 3% NaCl solution containing sand particles (5000-9000 ppm) and saturated with CO/sub 2/ at defined partial pressure (0-0.3 MPa) and temperature (30-60/sup 0/C). The effect of residual O/sub 2/ content (10-1500 ppb) was further examined. Two flow geometries were studied: 1) undisturbed pipe flow and 2) submerged jet impinging (30-90/sup 0/) onto a flat plate. The effect of specimen surface treatment (shot-blasting or pickling) was examined with dry polished material as a reference. Weight-loss and electrochemical measurements were applied to determine average and instantaneous corrosion rates respectively. The results are discussed in relation to fluid flow conditions and the surface preparation/microstructure of materials tested.
