HakaGerodur Piping Systems
Plastics, with all of its immense possibilities and broad range of applications, is our business. HakaGerodur pipes, fittings and accessories are specified by engineers, architects and planners worldwide for heating, cooling, sanitary, geothermal, extruded profiles and medical piping installations.
Our piping systems offer proven solutions to customers' challenges across a broad list of categories including: pressure (hot and cold), sewer, cable conduit, winding pipes and ducts, and specialty applications. HakaGerodur collaborates closely with customers in areas such as: piping systems calculations, consultation on pipe-laying technologies and assistance for project tenders. We are pleased to offer customers the benefit of our expertise and experience. It is an important part of what we do.
Serving customers worldwide
HakaGerodur's piping systems business is truly global. Based in Switzerland, we manufacture our product range according to the high quality benchmarks and recognised standards of that region and the EU, and we deliver to customers worldwide. HakaGerodur maintains high levels of stock readiness which offers the benefits of short-cycle planning and assurance of supply, particularly to our concentrated markets in Western and Eastern Europe.

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
- Surface heating and cooling (floor, wall, ceiling)
- Radiator connections
- Drinking water installation
- Industrial applications
Approvals / Standards
DVGW (German Technical and Scientific Association for Gas and Water) approval:
– CSTBat – 167-988
- SKZ monitored (SKZ symbol A161)
- Properties in accordance with DIN 16868 / 16869 and DIN EN ISO 15876-2
- Oxygen-tightness (multilayer pipes) in accordance with DIN 4726. Coating the pipes with an EVOH layer achieves a high barrier effect.
- Operational range max. 95°C, max. 10 bar, constant temperature 70°C.
- Pipes made of PB are corrosion free. A reaction of the materials and their alteration can be excluded.
- Excellent stress crack resistance
- Very flexible, tight bending radius and easy to lay (also cold laying)
- No incrustation due to smooth inner pipe surface
- Low linear thermal expansion
- Resistance to thermal and mechanical loading
Heating & Sanitary
HakaGerodur has decades of experience in the production of high quality piping for heating and drinking water. We manufacture comprehensive piping systems, comprising plastic pipes and plastic-metal composite pipes; and pipe-fixing technology including fittings, laying tools and specific installation tools. Our project offer is completed with calculation diagrams and technical documents.
GEROtherm – HakaGerodur's geothermal systems are applicable for the extraction of geothermal energy or to deduct (store) surplus heat in the ground. Geothermal systems can be constructed using both closed vertical or horizontal piping systems and the GEROtherm range also includes geothermal probes, horizontal earth collectors, collectors/distributors and energy piles.
HakaGerodur has decades of profile extrusion experience and employs the latest technology high volume production. We work with customers to design and produce custom profiles for a broad array of end uses and markets. In addition to the production of extruded profiles, we offer in-house design, engineering and tool making services.
We produce high-quality plastic pipettes and other derivative medical products conforming to international medical packaging and product standards. HakaGerodur utilises vertical manufacturing capabilities for its medical products including plastics processing, ultrasound welding, printing, packaging and sterilisation.
Pipe in corrugated pipe
The pipe is drawn into a corrugated pipe at the factory. This protective pipe is available in the colours red, blue and black. It is recommended especially for drinking water installation and radiator connections.
Polybutene pipes with prefabricated cold / heat insulation of thermally welded, extruded PE foam with a protective layer of a PE film are suitable for drinking water installations and radiator connections. The outer layer offers additional protection against UV radiation as well as against mechanical loading.
- Closed cell structure
- Temperature resistant
- Good thermal insulation
- Easy to assemble due to good bending properties
Accessories and tools
HakaGerodur offers accessories and tools for the use of polybutene pipes and their laying (pipe cutters, calibrators, flexible springs, oneman coilers, presses, press jaws and much more).
The mounting rail for underfloor heating developed by HakaGerodur engineers meets all functional needs and complies with the technical building requirements of professional associations. It is an extruded U-shaped fixing rail with stamped out pipe holding clips.
- Light, compact and low
- Quickly inserted and clipped in place
- Fixed to thermal insulation with double-sided adhesive tape or with fixing needles.
- Rail lengths 2.10, 3.00 and 3.90 metres
