Title: Corrosion failure of duplex stainless steel equipment in a PVC plant

Abstract

After <9 months of operation in a polyvinyl chloride (PVC) manufacturing plant, alloy 2205 duplex stainless steel (UNS 31803) columns and spiral heat exchangers (HXs) were corroding and cracking. The columns were repaired and remained in service but the HXs needed to be replaced. Candidate materials for the HXs were assessed, and it was found that the super-austenitic alloys containing 6% molybdenum would be more appropriate for this application.
