High-Quality Layup for Best Properties
High-quality raw materials, a special ECR glass fibre quality, a resin system tailored to UV light curing as well as films are the foundations for our different Alphaliner designs.
Alphaliners are manufactured in continuous production up to approx. 300 m of individual lengths. Using pre-impregnated glass fibre tapes, liners with a diameter of DN 150 - DN 1800 are rolled into a continuous flexible hose. This helical winding creates their characteristic look on the inner surface.

Depending on the requirements for chemical resistance, we use a variety of synthetic resin systems: polyester resins (UP), vinyl ester resins (VE) as well as styrene-free vinyl resins.
For the different Alphaliner models, we apply special ECR glass fibre qualities with a variety of mechanical characteristics depending on their structural stress load capacity.
We then package the Alphaliners into particularly robust multi-layer composite film, depending on the respective Alphaliner model.
