•••• pipeline fittings (standard & special fittings)

•••• hollow bars and solid rods

•••• construction of tools or machines

• 1970 Mr. Reinert founded an engineer’s office for plastics technology in Radevormwald (approx 200 km in south from Nordhorn )

• 1992 Construction of a 2nd plant in Nordhorn

• 1995 Stop of plant in Radevormwald

• Since this date continuous extension of our program �� building new halls

1. Economical pipe fittings for gas and water supply applications

2. Large diameter for PE pressure systems

3. New products

• User friendly solutions

• Prefabricated manifolds

4. Welding or use of coupler? Comparison: butt welding, electro fusion sockets and push fit coupling

Development of PE

50 Years PE pipesfor gas and water supply

• flexibility (pipes in variable lengths)

• resistance against corrosion

• safety, less damages cases

• easy laying (welding)

gas supply:

•PE transport pipelines for gas are normally used until DN 200

•Some big cities until DN 350e.g. London (England) up to DN 600

today DN 600 or even larger

-water supply:

PE up to DN 200 is more economicalthan cast iron (in the opinion some major

water companies)

3. New products

4. Welding or use of coupler? Comparison: butt welding, electrofusionsockets and push fit coupling

4. Welding or use of coupler? Comparison: butt welding, electro fusion sockets and push fit coupling

- Push fit systems

CONNECTION: PE pressure pipe systems

- Butt-welding > DN 200

- Electro fusion < DN 300

• pull resistant push fit coupler for PEpressure pipe systems up to 16 bar

• body of socket made of PE100-RC

• with GRIP elements made of technical plastics• Elastic mounted single elements • Lip seal, EPDM system 3S(drinking water quality - KTW approval)

• use: water - gas on request –

• advantages:- ring made of elastomer generates pre-loading- Profile ring repulses mud- simple installation due to push-fit system,- quick pipelaying (without cooling time)- no welding operators required- independent of the weather conditions,- no electric power supply required, - no welding and peeling machines required

- PE 100 – SDR 17/ 11

- DN 200 – DN 600 (- other dimensions on request-)

- consisting of: EU-piece with Tyton-gasket, internally enamelled,

bolts hot galvanized

- spigot sufficiently long for electrofusion welding or

other lengths on request

- Advantages: weldable on one end, one flange less = cost reduction,

easy installation, �� adjusting +/- 40mm

Example: Airbus HamburgDN 600/710 mm, 16 bar

TEE with inspection outletdiameter branch bigger than

diameter main pipe

- PE 100 – SDR 17/ 11

- up to d 1600 mm

- branch with special flange connection

DN 250/ d 315 mm or as requested

- Advantages: - weldable

- homogeneous

TEE with inspection outlet

• Increasing trend to larger diameter for PE pressure systems

• Economic development of fittings(more stability, reduced costs)

• Design, construction and rating
