Multi-layer PP pipe reaps benefits from fibreglass reinforcement
KraussMaffei Berstorff has helped German plastic pipes manufacturer Poloplast develop a special concept for manufacturing five-layer PP-R pipes with fibreglass reinforcement. The system was commissioned at
Poloplast‘s plant in Bavaria late last year. Poloplast has received product approval and authorisation to produce the pipes for drinking water and air-conditioning systems (for the diameter range of 32–250mm). “In a challenging development
process that involved various tests and a wide range of providers, KraussMaffei Berstorff impressed us the most,” said David Zovkic, head of production at Poloplast. “The pipe head concept meets our high standards for material composition and quality.” Part of the development was to redesign the spiral distributor

Italian ancillaries company Piovan is presenting the latest additions to its Aquatech brand at this year’s Plast. The brand, which specialises in industrial cooling, includes its Easycool+ range of air-cooled chillers. The show also sees the Italian debut of Easytherm, its new temperature control line, which it says is “Industry 4.0 digital factory-ready thanks to the OPC-UA protocol”. A new internal and external layout, rede-

signed ergonomic controls and a combination of high-end components make it a versatile unit that allows smart energy use manage- ment, according to the company.
At the same time, the company’s Winenergy and Winfactory 4.0 are featured on touchscreens. Winenergy is the energy use monitor- ing and analysis system comprising proprietary software that is connected to a series of measuring devices – which acquire data about a variety of physical parameters including
power, electricity, thermal energy and temperature. It can be installed on its own or in combination with Winfactory 4.0, to maxim- ise system control and efficiency. Piovan is also showing its Quantum E gravimetric batch blender with continu- ous extrusion control, and demonstrate a system comprising a Pureflo filterless granule receiver, Modula series auto-adaptive drying system, and Quan- tum Q7 batch blender for medical applications. �

system design in order to meet the requirements for the thickness of the individual layers, according to Andreas Kessler, general sales manager for KraussMaffei Berstorff in Munich. The extruder/pipe head combination has been designed to save a lot of space.
The KME 45-30 B/R main extruder,
which features the KM-5L RKW 94-250 pipe head to make the PP-R interme- diate layer, is surrounded by four co-extruders from the same series, plus a KME 20-25 B/R co-extruder for applying strips. This allows the machine operator to control and monitor production from a central position. The pipe head has energy- efficient internal pipe cooling (IPC), which ensures precise heat balance for thick-walled pipes. PP-R pipes with fibreglass
reinforcement offer low elongation and bending. This gives them much higher stiffness. The pipes are often installed so that they are exposed under suspended ceilings – espe- cially in public buildings, says the company. �
