Examples of Some Materials Vulnerable to MIC

Without a doubt, the choice of material is an important factor to make a system resistant or vulnerable to MIC. Case histories show that carbon steel is a more susceptible material in comparison with stainless steels, and that stainless steel SS316 is more resistant than SS304. [Pg.123]

On the other hand, concrete, thanks to its composite structure that takes advantage of both steel and cement, has an inpossible-to-ignore position among other materials, especially in the sewage treatment industry. [Pg.123]

We start this chapter with copper alloys, as none of other materials have the so-called bio-resistance of copper. [Pg.123]

Almost all types of engineering materials have been reported to experience MIC by SRB copper, nickel, zinc, aluminium, titanium and their alloys [96, 97, 98], mild steel [72, 99, 100], and stainless steels [68, 80, 101, 28] are just some examples. Among duplex stainless steels, SAF 2205 has been reported for its vulnerability to MIC [44, 102, 103]. According to these studies, SAF 2205 can corrode and have pitting initiated due to the presence of SRB after immersion in seawater for more than one year (18 months) [102]. Corrosion rates of lOmm/year [5] in oil treatment plants and 0.7 mm/year to 7.4mm ear due to the action of SRB and/or acid-producing bacteria in soil environments [8] have been reported. [Pg.54]
