UV Light Curing

Examples for Thick-Walled Lining Tubes

UV curing of a lining tube for a DN 1750 sewer without the addition of peroxides.

  • Length of the sewer to be rehabilitated: 110 m

  • Diameter DN 1750

  • Composite wall thickness of the lining tube: 17 mm

  • UV curing system with the continuously electrically extendable UV core with a UV spot output of 6 x 4000 watts (total UV spot output of 24,000 watts)

The curing process with all parameters such as pressure, temperature, curing speed and the actual power of all UV lamps used in the curing protocol was logged.  For the 110 meter long lining tube with 17.0 millimeter wall thickness, the curing chart showed a speed of 0.27 meters per minute. [Reline2000].

UV curing of a lining hose for a DN 2000 sewer without the addition of peroxides.

  • Length of the sewer to be rehabilitated: 164 m

  • Diameter DN 2000

  • Composite wall thickness of the lining tube: 11 mm

  • UV curing system with a UV spot output of 3 x 6 x 2000 watts (total UV spot output of 26,000 watts)

The curing process took 4 hours [BI02-21].
