The new factory Commissioned: Size of grounds: Production facilities: Extrusion hall: Extrusion lines: Dimensional range: Pipe raw materials: Rated capacity/year: January 2001 150, 000 m² approx. 18, 000 m² 90 m wide, 150 m long 14 DA 7 – 1200 mm PE and PP 55. 000 tonnes
Pipe Installation back then…. and today! Strong growth in non-conventional installation techniques over the past 20 years Civil works up to 90% only 10% pipe material Open Installation Quelle: Fiedler, Göttinger AWT 2006 Up to 50% cost for surface restoration Quelle: A. Hügging in 3 R international (2000) Non-conventional pipelaying saves money – however, requirements Trenchless by Relining Quelle: Gelsenwasser towards pipe material are higher!
Development of PE-HD as a Material for Pipes Perfomance PE 100 RC 0 10 E P 3 rd Generation 80 E P E 6 P 3 1970 2 nd Generation 1 st Generation 1980 1990 Year 2000
Polyethylene : Molecular Structure HDPE: filamentary macromolecule with a few branches Polyethylene molecule crystalline structure branches
Influence on Materials Properties PE-molecule Structure short molecules without branches crystalline long molecules with branches Property high stiffness high strength amorphous high ductility high crack resistance high resistance against scratches and notches crystalline amorphous
Increase of Resistance against Slow Crack Growth SCG by Comonomer Branches without with Comonomer
Today: 3 rd Generation PE 1. Generation: monomodale - without comonomer 2. Generation: monomodale - with comonomer 3. Generation: bimodale - with comonomer Content [%] monomodale bimodale Increasing the crack resistance: Comonomer branch in longest macromolecules Chain length By bimodal distribution strength and ductility were equally increased

Trench Installation without Sand bed Scoring Point load Ploughing Milling Sand bedding unnecessary thanks to modern materials • Use of excavated soil allows quicker and more cost-effective installation. • In Rural regions modern techniques like ploughing and milling decrease the contracting time • Additional point loads are exert on the pipe during its live time by stones • Pipe system need to be stable against these point loads, so that these do not result in stress-induced cracking 8 Special Quality Control of the slow crack properties guarantees the long lifetime of these pipes !
