Insidious flow-accelerated corrosion (FAC) is a widespread problem in conventional fossil plant feedwater systems and combined-cycle HRSG tubing. FAC is so prevalent, in fact, that it can be difficult to prioritize inspections and reach repair decisions. Structural Integrity Associates, Inc. (SI) eliminates the guesswork by offering its clients comprehensive FAC support programs. SI's specialized services include assessment and optimization of unit cycle chemistry; piping assessments based on drawing reviews and system walkdowns; predictive assessments of FAC risk; inspection prioritization; damage screening via guided-wave analysis; ultrasonic remaining-thickness assessments; data management; guidance on damage repair options and approaches; periodic operating reviews; and FAC program improvements.
