Abstract

Pitting corrosion susceptibility of some super austenitic stainless steel tubes exposed to flowing sea water in a specially designed test rig was investigated by field tests and laboratory analyses. The middle part of the steel tubes was put under elevated temperature in the steam chamber part of the rig. The tubes brought to the laboratory were examined with the Wild M3C Model optical macro/microscope after splitting and cleaning. The scanning electron microscopy, (S.E.M.) was used to examine and analyse the observed microscopic pits and microbiological. organisms. EDAX (Energy Dispersive X-ray spectrometer; and the X-ray Diffraction spectroscopy (XRD) analyses were performed on the biofilm at the outlet-portion of some of the tubes: This paper reports the observed pitting corrosion behavior of the tubes' alloys. Pitting ·corrosion susceptibility was found to be .generally very minimal except for the 316L alloy which was used for comparison purpose
