Pipe rehabilitation with Amiblu non-circular
GRP pipes (NC Line)

When spot repairs on deteriorated pipelines are no longer feasible, authorities are confronted with having to decide between rehabilitation and pipe replacement. The latter solution has the disadvantage of being very costly and disruptive to urban areas where the largest sewer networks are located. A convenient solution to this problem is pipe rehabilitation – for example in the form of relining.

Relining creates a leak-tight “pipe within a pipe” system, which is as good as new in both structural and hydraulic terms. Amiblu NC Line pipes with their non-circular cross-sections are ideal for relining old city sewers, culverts and channels that often hold non-circular shapes. The non-circular profiles are produced using a filament winding technology. They can be customized according to customer demands and easily be adapted to different types of shapes and geometries. The remaining annular space between the host and liner pipes is usually filled with grout. This fixes the inserted pipe in its position and can take over the structural load.

Advantages of Amiblu non-circular pipes:

  • high corrosion resistance that is proven by long-term testing
  • custom-tailored profiles according to customer demands
  • easy adaptation to different types of shapes and geometries
  • proven sealing system that allows excellent tightness and easy joining,
    also under angular deflection
  • installation possible irrespective of the weather
  • light weight and easy to transport and handle
  • expected service life of more than 150 years
