Krauss Maffei provide a complete solution for direct extrusion of mineral filled PP Pipe, available from HBM

Features of the extrusion line include:

• Complete downstream for pipe production – calibration, cooling, haul-off, sawing, chamfering and socketing
• The polypropelene pipe is extremely stiff and impact resistant, and PP block polymer is used for the middle layer, which is fed into the extruder’s main feed throat via gravimeter differential scales
• Stabilizers and colour masterbatch are also offered in the extrusion line
  
• 70% by weight barium sulphate is fed into the side feed throat
• A KM-ZSP 90 gear melt pump generates the necessary die counterpressure
• The complete extrusion line is controlled by the main extruder’s C5 controller
• The extrusion line is configured to produce pipe from 50 to 250 millimetre diameter and for output up to 700 kg / hr
• The output of PP melt highly filled with barium sulphate can be directed to an underwater pelletizing unit via a hydraulic switchover valve
