Effects of Chloride Contamination on Performance of Tank and Vessel Linings

Nine, commercial ly available, ambien t cured, thin-f i lm lining sys t ems were evalua ted for their tolerance to var ious levels of na tu ra l and artificially applied chloride con tamina t ion on steel subs t ra tes . The l inings were tes ted by immers ion in water or h y d r o c a r b o n / w a t e r at var ious t empe ra tu r e s for a du ra t ion of 13 and 6 m o n t h s respectively. The tolerances to chloride were found to vary significantly among the linings. In addit ion, the m a x i m u m service t empe ra tu r e s of the l inings were progressively reduced as the chloride levels increased.
