To boost productivity of PPR pipe manufacturing, LIANSU has developed high-speed PPR pipe extrusion line for pipe sizes ranging from 20 mm to 75 mm. It supports both mono-layer and multi-layer pipe extrusion, delivering a maximum line speed of 25 m/min ×2 and an output up to 450 kg/h. Combining high-speed dual-pipe extrusion and full-line automation, the PPR pipe extrusion line boosts throughput and reduces labour dependency.
The single screw extruder is engineered for the material characteristics of mono/multi-layer PPR and high-speed extrusion conditions. Optimized screw geometry ensures steady material conveying, thorough plasticization and homogeneous blending. Fitted with two strand pipe head, its spiral flow channels deliver uniform melt temperature and flow distribution. This guarantees consistent wall thickness across layers, minimizes inner pipe weld lines, and eliminates the streaking defects commonly seen on conventional basket-type pipe heads.

The granule loss-in-weight feeder is fully integrated into the line PLC to precisely control the weight per metre of finished pipes. The gravimetric doser (for granules) doses masterbatch by loss-in-weight according to the set recipe, ensuring stable colour addition. It also supports fast in-line colour changeover, reducing purging time and material waste for stable high-speed production.

A closed-loop vacuum tank control system enables rapid pipe forming with real-time vacuum monitoring for traceable quality records. The haul-off and swarfless cutting units run in precise high-speed sync to maintain consistent product quality. The integrated packaging station supports heat-sealed polybags and stitched woven sacks, with online weight inspection and labelling to match the high-speed PPR pipe extrusion line's continuous high-throughput production.


Production efficiency depends not only on machine speed but also on day-to-day management. Equipped with the Flexcon+ flexible control system and data management system, the line records production data, energy consumption, and equipment operating status. It also supports maintenance management and remote monitoring, helping factories track equipment performance and plan routine maintenance.

LIANSU delivers a complete turnkey pipe production solution, from raw material handling and extrusion to downstream automation and intelligent control, to accommodate diverse production requirements. For more info, please contact us: +86 13392775773.
