The pipes are produced in a high-tech pipe machine with a continuous joining process quality assured according to ISO 9001. The pipe material is composed of polyester, glass fibre and sand. The corrosion and barrier layer consists of surface mat and chopped glass fibre.

We offer a complete pipe system, with a large number of fittings. The most common method of joining is to use a double socket. Other joining methods are flange joints, lamination or mechanical couplings.
