Non-Circular GRP Pipe & Fittings

Non-Circular GRP Pipe & Fittings

Non-circular Glass Reinforced Polyester (GRP) pipe and fittings are suited for both the trenchless rehabilitation and open-trench construction of sewage and wastewater pipelines.

Our range of non-circular GRP pipe and fittings are manufactured using a high-strength filament winding process and can be made to virtually any shape.

  • Comes in a variety of profiles, including egg, elliptical, oval and others.

  • Custom profiles, fittings and manholes available.

  • High bending strength provides new structural integrity to existing channel walls.

  • Available stiffness ratings between SN 2500 - SN 10,000.

  • Easy to install rubber ring joint (RRJ) and laminated joint options available.

  • Engineered for a 100+ year design life.

Overview

The GRP non-circular pipe is unique because it offers more stability than a pipe liner for rehabilitation projects. It provides structural strength to the existing channel walls for a longer design life.

Our suite of non-circular GRP pipe and fittings are readily available in a range of standard pipe lengths of between two and three meters, which are suitable for most applications.

However, we also have the capability to provide lengths of up to six meters depending on unique project requirements.

The interior of the pipe wall is resistant to the abrasion effect of wastewater and has excellent hydraulic properties.
