In the plastics industry, the raw material is delivered in granulate form and stored in aluminium silos until it is processed. At our site in Benken, the silo plant was expanded. The installation of the silos is always spectacular. See for yourself!

We focus on assisting our customers to stay competitive in dynamic markets:


Piping Systems

Trusted solutions for diverse piping systems applications including pressure (hot and cold), sewer, cable conduit, winding pipes and ducts, specialty and custom designed installations.

We produce piping systems including:

Polybutene Piping Systems

HakaGerodur produces polybutene (also known as polybutylene or PB) pipes with up to three layers. While the single-layer version is configured for drinking water installations, the three-layer pipes are oxygen tight in accordance with DIN 4726 and therefore suitable for heating systems and other areas. The entire HakaGerodur range is backed by decades of experience in plastics processing. And this vast pool of knowledge provides a significant customer benefit.

Structure / Material
Plastic pipes are extruded from the especially flexible and durable basic material of polybutene. The material is melted, shaped and then cooled. The adhesive between basic pipe and barrier layer allows force-fit and permanent jointing. Single-layer pipes without oxygen barrier are used for drinking water installations and in industrial applications. The pipes are jointed either by welding or with push-in connectors. For this purpose material PB 4237 grey is used. Multilayer pipes are installed in heating systems. The material used here is the quality PB 4235 beige.


Ø 6 mm to 110 mm
Special dimensions and special tolerances can be manufactured on request
