BE-13 Renovation: Lining with Cured-In-Place Pipes - Processes - v01

Heat-Initiated Curing / Hot Curing

Hot Curing with Steam – Procedure

  • Inverted-in-place insertion of the lining tube by pressurized air

  • Installation of valves in the closed end of the lining tube in the target manhole so that the pressurized air can escape from the tube in a controlled manner during the curing process

  • Starting the curing process by blowing in a steam/air mixture

  • Excess steam escapes in a controlled manner via the valves

  • Control of the steam temperature as well as the temperatures between the lining tube and the host pipe via a calibrated temperature sensor

  • Cooling phase while maintaining the internal pressure
