摘要：
CO2/H2S corrosion behavior of tubular steel SM 80SS have been investigated utilizing electrochemical measurement technology, weight loss test, scanning electron microscope (SEM) and X-ray diffraction (XRD). The results showed that temperature increased the corrosion rate and changed the corrosion mechanism of tubular steel SM 80SS. Cl− quickened the anodic dissolution and increased the corrosion rate of tubular steel SM 80SS. Furthermore, the addition of Ca2+ and Mg2+ resulted in the corrosion products changing from crystalline FeCO3 to amorphous Fe(Ca,Mg)(CO3)2 and serious corrosion under scale of tubular steel SM 80SS.
