Reclamation Information Sharing Environment (RISE)

This scoping level research conducted market research to identify potential refurbishment solutions for small diameter embedded pipes that suffered extensive corrosion in powerplants and dams, examples are drain pipes, vent pipes, and bypass lines. Small diameter metallic pipes were typically installed uncoated, and rarely condition assessments are conducted during comprehensive or periodic facility reviews (CFR’s) or (PFR’s). Reclamation’s aging infrastructure exceeds 70 years and corrosion has compromised the pipes. These pipe diameters are less than 24 inches and notoriously hard to repair or reline and could be embedded in mass concrete, making replacement not an option. Cured-in-Place Pipes (CIPP), Spray-in-Place Pipes (SIPP), Fiber Reinforce Polymers (FRP), cement mortar lining, and polymeric linings were investigated for suitable refurbishment techniques.
