Inpipe Flexliner

Inpipe Flexliner is specialized for renovating pipes with dimension- and shape changes.

When using Inpipe Flexliner, you only need to know the largest and smallest dimension, or circumference of the pipe, to manage the renovation. The liner is made of fiberglass-reinforced polyester, also available as a styrene-free alternative. Inpipe Flexliner can handle dimension changes of up to 150 percent, depending on the dimension of the pipe.


  • Easy to install with inversion or winch-in-place
  • Adapts to dimension changes anywhere in the pipe – up to 50% depending on dimension
  • Minimum gap between pipe and lining (< 0.1% of diameter)
  • Up to 100 years of life
  • You do not have to measure and fit a “sewn-in” liner
  • An obvious choice when you come across pipes that are not standard in dimension
  • Up to SN5 depending on diameter
