Abstract
The flow-induced corrosion behaviour of welded low ally steel in 1 wt. % NaCl
environment containing monoethylene glycol at 0oC and 25 oC respectively, was investigated.
A modified submerged impinging jet rig was adopted to simulate the low temperature
environment. Varying speeds between 1 and 3 m/s were used to study the degradation
mechanism of the welded steel. Also, the ratio of MEG: 1 wt. % NaCl was kept at 1:4 for the
MEG/NaCl solution. Static corrosion condition was also studied and compared with the
flowing conditions. Results indicated that the alloy degraded with observable weight loss in
pure 1wt. % NaCl at both temperatures whereas there was very negligible weight loss in all the
samples in MEG/NaCl solution.
