2 The new factory Commissioned: January 2001 Size of grounds: 150,000 m² Production facilities: approx. 18,000 m²Extrusion hall: m wide, 150 m longExtrusion lines: 14Dimensional range: DA 7 – 1200 mmPipe raw materials: PE and PPRated capacity/year: tonnes
3 Pipe Installation back then…. and today!Strong growth in non-conventional installationtechniques over the past 20 yearsQuelle: Fiedler, Göttinger AWT 2006Open Installationonly 10% pipe materialCivil works up to 90%Up to 50%cost for surface restorationTrenchless by ReliningQuelle: GelsenwasserQuelle: A. Hügging in 3R international (2000)Non-conventional pipelaying savesmoney – however, requirementstowards pipe material are higher!

11 Trench Installation without Sand bed 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 crackingScoringPoint loadPloughingMillingSpecial Quality Control of the slow crack properties guarantees the long lifetime of these pipes !
