PP / PE corrugated pipe production line is a fully automatic, single-screw extrusion system engineered for the continuous manufacture of single-wall or double-wall corrugated pipes from 16 mm up to 1200 mm in diameter. The line processes virgin or recycled polypropylene (PP) and high-density or low-density polyethylene (HDPE / LDPE) into lightweight yet high-strength pipes that are widely used for cable protection (electric, telecom, fiber-optic), storm-water drainage, agricultural irrigation, building ventilation and automotive conduit.
Core Components

High-torque Single-screw Extruder – 30:1 or 33:1 L/D barrier screw with grooved feed zone guarantees homogeneous melt and ≥ 95 % plasticization even with high CaCO₃ filler.
Co-extruder (optional) – for colored stripes or adhesion-modified inner layer.
Die Head – spiral or basket style; quick-change tooling for OD 16–75 mm, 50–250 mm, 200–600 mm or 500–1200 mm ranges.
Corrugator – precision vacuum calibrating blocks in aluminum alloy or high-strength resin; servo-driven, open-close design for fast size changeover.
Cooling Tank – spray and immersion sections ensure rapid shape fixation.
Haul-off – caterpillar or belt type with synchronized speed to corrugator, ±0.5 % tolerance.
Cutter – planetary or chipless saw with PLC length control (±2 mm).
Automatic Coiler or Stacker – torque-controlled for neat packaging.
