Don’t Lose Your Head – A Case Study on the Repair of a Vertical Knock-Out Drum

A 67” vertical knock-out drum suffered a system upset over three years ago resulting in a localized band of internal corrosion near the entire circumferential dome weld. After performing initial defect assessments it was determined that the pressure vessel could not operate at full capacity without suffering rapid through-wall defects around the entire circumference. Additionally the corrosion occurred beneath the lowest support meaning that a structural failure would result in the drum head detaching.To provide a short-term remediation a composite repair system was custom designed for the operator to address the three primary concerns: through-wall leaking internal pressure containment and preventing dome separation. Three unique systems were combined and used to achieve a successful repair for over three years while a replacement drum was ordered for the next turn-around. This paper will highlight the flexible design capabilities of composite materials in addressing critical component repairs when engineered appropriately.
