Analysis of pitting corrosion failure of copper tubes in an apartment fire sprinkler system
2016, Engineering Failure AnalysisCitation Excerpt :Both samples were a little alkaline with almost the same pH value of 8.25. This pH value is well in the so called passivation region where the copper oxide protective layer is formed, preventing further oxidation of copper [5] (see Pourbaix diagram of Fig. 14). Na, Cu, Zn, and Fe were analyzed by AAS while Mg, Ca and Al were analyzed by ICP/OES.
Hot-water corrosion failure of a hard-drawn copper tube
2013, Engineering Failure AnalysisCitation Excerpt :High chlorine content likely stimulated the pit initiation and growth. It is considered essential for pitting attack by aiding the breakdown of protective surface layers and inducing to the formation of wide, shallow pits [16]. The composition of flowing medium had likely contributed to the formation of fragile and loosely adherent scale products, primarily mixed (hydroxy)chlorides, such as CuCl2⋅3Cu(OH)2, and secondarily sulfates, phosphates, that they can easily be detached and sustain the corrosion process, see also Ref. [17].
