Corrosion of Butterfly Valves in Sea Water Service.

Abstract

Electrochemical techniques were used to compare the corrosion resistance in sea water of butterfly valve components made from an alloy which did not meet compositional requirements to components made from the specified Monel alloy 400. Polarization resistance studies indicated that the alloy which did not meet the specification had corrosion rates several times higher than Monel in both aerated and de-aerated sea water. Anodic polarization studies also showed that this alloy had a much higher probability for propagation of localized corrosion than Monel. Thus components made from this alloy can be expected to provide poorer service than those made of Monel. (Author)
