The liner is one of two key components of Primus Line®.

As an installation solution it serves the rehabilitation of pressure pipes, and stand-alone it functions as a robust flexible line. The ability to structurally support itself enables its use without wet out, curing or adhesion to the host pipe.

Versatility through three-layered composition

Outer layer made of polyethylene (PE) for protection from external effects during transport and installation
Reinforcement made of one- or two-layered aramid fabric, depending on the required pressure rating
Inner layer made of polyethylene (PE) or thermoplastic polyurethane (TPU), dependent on the medium

With its multilayered composition and slender wall thickness the liner combines flexibility with an extremely high material strength.
