Refinery Cooling Tower Riser Pipe Repair

Carbon Fiber Strengthening of Cooling Tower Risers

Problem vs Solution
  • Thin wall and through-hole defects were present due to soil air interface corrosion (SAIC)
  • 12 risers required repair during a short window and needed a 200 psi design pressure
  • CarbonSeal™ was designed to fully restore the structural integrity of the pipe and provide a leak-proof barrier that was resistant to future corrosion
  • Riser were excavated 10-ft to expose sound substrate and all active leaks were stop-gapped until the CarbonSeal Repair System was allowed to cure
  • Service life was extended 15 years
