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. 300m of individual lengths. Using pre-impregnated glass fibre tapes, liners with a diameter of DN150 - DN1300 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/VEU) 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.
