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. Amiblu non-circular pipes are also used for open trench applications. The non-circular profiles are manufactured in a discontinuous process by helical filament winding. Resin impregnated continuous and chopped fiberglass rovings are wound on a rotating oval mandrel with controlled sequences. Using this technology, a very dense laminate is created that maximizes the contribution from the three basic raw materials: glass fibers, resin and sand. Amiblu NC Line can be customized according to customer demands and easily be adapted to different types of shapes and geometries.
Amiblu NC Line adheres fully to ISO 16611. The ISO 16611: 2017 sets strict guidelines for how non-circular pipes can be produced and tested. External bodies confirm Amiblu compliance.
