Amiblu non-circular pipes (NC Line)

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. Non-circular pipes are also used for open trench applications. They can be customized according to customer demands and easily be adapted to different types of shapes and geometries. Amiblu NC Line meet the requirements of ISO 16611.

Non-circular profiles

The egg shape profile is ideal for combined sewer systems. The narrow profile in the lower section of the pipe ensures a good water flow for sewage, while the upper and wider section handles heavy rain.

Nominal size*300-4000 mm
Pressure (PN)1 bar
Nominal lengths500-3000 mm
ThicknessLoad-carrying or non load-carrying profiles available

The mouth profile is ideal for culverts under the road, to collect streams and small rivers. The shape allows for inspection by personnel.

Nominal size*300-4000 mm
Pressure (PN)1 bar
Nominal lengths500-3000 mm
ThicknessLoad-carrying or non load-carrying profiles available
NC Line arch profile illustration

The arch profile is ideal for culverts under the road, to collect streams and small rivers. The shape allows for inspection by personnel.

Nominal size*300-4000 mm
Pressure (PN)1 bar
Nominal lengths500-3000 mm
ThicknessLoad-carrying or non load-carrying profiles available

* Nominal size referring to ISO 16611, i.e., maximum inner height and breadth. The above-mentioned are the most commonly used profiles. Other profiles are available on request. Most profiles can be manufactured with a dry-weather channel.
