FLEXIROHR METHOD

Renos Flexirohr relining pipe is an economical and fast method for the relining of gravity sewers in DN 100-300 mm. The ring stiffness class of the pipe is SN8 (DE 270 Flexirohr is SN4). Flexirohr is installed through existing manholes with a winch and a wire. In the smaller dimensions installation can even be performed manually. The inner diameter of the relined pipe is reduced one diameter smaller.

ADVANTAGES AND BENEFITS OF THE METHOD

  • Factory produced pipe (SN8 or SN4) means a long-lasting solution, lifetime over 50 years
  • Tight, continuous, welded system without digging
  • Sewer can be functional during installation means no bypass needed
  • Fast and efficient installing means less harm to traffic and the citizens
  • welded to exact lengths for each section means no waste
  • corrugated pipe structure means lower usage of oil and lower weight
  • No toxic waste
  • Pull-resistant couplings

ADVANTAGES FOR THE INVESTOR

  • a long-lasting solution lifetime over 50 years
