The KDR Series is a twin screw helical extrusion line of Krah, which is a complete plastic pipe production plant, to produce structured wall (acc. DIN16961 etc.) or solid wall pipes by using fillers like CaCo3/Glassfibre etc., on internal diameters from DN 300 mm up to DN 5000 mm made out high density polyethylene/polypropylene, reinforced/mixed with glassfibre or CaCo3. Glassfibre reinforced polyethylene (PE-GF) Polyethylene/polypropylene with filler material Virgin polyethylene or polypropylene In a huge market of competition, cost savings by using filler materials becomes more and more important for pipe manufacturers. The production technology with the twin screw extruder is compounding filler material with the polyethylene or polypropylene to assure the same stiffness or pressure rate compared to traditional produced pipes. The glassfibre reinforced polyethylene pipes (PE-GF) are mainly used for pressure pipe application and pipe jacking. The compound with filler material are used to increase the stiffness significantly for buried pipe application. Production line can be equipped for solid wall production only as also for profiled wall structure pipes.
