Customized special system for 5-layer PP-R pipe with fiberglass
| Subj: Machinery
KraussMaffei Berstorff worked in close collaboration with Poloplast GmbH, a leading plastic pipe manufacturer and longtime customer of KraussMaffei Berstorff, to develop a special concept for manufacturing 5-layer PP-R pipes with fiberglass reinforcement. The system was successfully commissioned at the Poloplast’s plant in Ebenhofen, Bavaria, in late November of last year. Poloplast has also received product approval and authorization to produce the pipes used for drinking water and air-conditioning systems (for the diameter range of 32–250 mm).

The KME 45–30 B/R main extruder, which features the KM-5L RKW 94–250 pipe head for producing the PP-R intermediate layer, is closely surrounded by four coextruders from the same series, arranged in a half-circle, as well as the KME 20–25 B/R coextruder for applying strips. This set-up lets the machine operator control and monitor production from a central position. In addition, the pipe head features energy-efficient IPC (Internal Pipe Cooling), which ensures precise heat balance for thick-walled pipes.
The standout property of PP-R pipes with fiberglass reinforcement lies in their low degrees of elongation and bending. This gives them a stiffness that is many times higher, which in turn provides quite a few advantages when laying pipe. The pipes are very frequently installed so that they are exposed under suspended ceilings — especially in public buildings.
