Abstract: The plate heat exchanger in oil cooler of unit 2 in a thermal power plant became
corrosion perforation after 2-year running, and severe pits were found on its surface. The
material and scale composition of the lubricating oil cooler was analyzed, and it was found that
the oil cooler was made of 304 stainless steel, instead of the 316 stainless steel provided by
factory. The corrosion products on the corroded surface were composed of some characteristic
elements in cooling water. The analysis suggested that the reason for corrosion perforation of the
heat exchanger could be associated with its material composition, and the under scale corrosion
formed under the action of scale deposition could also cause corrosion perforation and
large-scale pits. © (2013) Trans Tech Publications, Switzerland.
