Follow-up order for complete system for production of multi-layered PE-RT pipes

axial spiral, while the layers of EVOH bonding material are distributed over three spiral distributors, and a conical spiral has been selected for the outer layer. The main advantage of this design is the exact distribution of the layers, which allows for a reduction of the material costs in pipe production. The pipe head is fed by six single- screw extruders, each of which is equipped with its own gravimetric material metering so that different layer thicknesses can be configured. In detail, the extruders are the KME 45-36 B/R main extruder for the PE-RT inner layer and the KME 30-30 B coextruder for the PE-RT outer layer. Two further coextruders of the KME 30-25 D/C type each plasticise the raw material for the layers of bonding material, into which the EVOH oxygen barrier layer is embedded. For these, a KME 30-25 is installed as a piggyback on the main extruder. The sixth extruder, a KME 20-25 D/C, also installed as a piggyback solution on top of one of the coextruders, takes over appliance of the strips.

This blade type is specifically suited for Rattunde Twin machines, but also for other applications where multiple tubes are cut, such as Bewo, RSA and Sinico machines. Kinkelder’s cutting experts can advise on the parameters for the application. Kinkelder Champion TL saw blades are available in diameters from 225 to 560mm with a pitch of 9mm, 11mm and 13mm.

systems with a diameter between 8 and 32mm for several years. The recently ordered system will be commissioned by the end of this year. “It was especially important to me to have a partner offering an integrative, customised concept, so to speak, a turn- key system enabling us to manufacture more than just me-too products,” said Enetec’s managing

ENETEC Plastics GmbH, Germany, has invested in its third complete extrusion line for manufacturing five-layered PE- RT pipes for heat exchanger systems. The company, which was founded in 2014, chose solutions fromKraussMaffei Berstorff. Two identical systems have already been producing heating pipe

director, Michael Frenzel, explaining his decision in favour of KraussMaffei Berstorff. The mechanical engineering com- pany was able to fulfil the requirements in such a way that the pipe manufacturer ordered its second line just nine months after the initial installation, and now has ordered its third. The highlight of the systems is the KM5L-RKW01-40 five-layer pipe head, which KraussMaffei Berstorff says is unique within the industry. Andreas Kessler, KraussMaffei Berstorff’s gen- eral sales manager at its Munich location, commented, “We have succeeded in designing a pipe head that combines multiple spiral distributor principles. Using the pipe head, manufacturing multi- layered pipes with perfect layer thickness distribution becomes possible at high line speeds.” The inner layer is led over an

extended with two new blade types. The Champion TL saw blade has been designed to cut tubes with tensile strength up to 850N/mm 2 on high output/ high quality stationary sawing machines. Due to a new carbide grade, a new PVD coating to obtain a very smooth surface finish, and a new tooth geometry and body design for better chip evacuation, this Champion saw blade has an improved blade life of typically 50 per cent and more compared to CX 3. A dedicated Champion TL Multi saw blade has been developed for multiple tube cutting with a tensile strength of

DUTCH saw blade manufacturer Kinkelder has extended its range of TCT Champion saw blades for high- performance tube cutting. Applying a new carbide grade, PVD coating, body design and tooth geometry, the Champion TL saw blade series contains the company’s latest innovations for TCT tube cutting. Over the past few years, the number of heavy-duty tube cutting applications has increased. Following performance feedback from the market and the demand for a new high-end TCT saw blade, the Champion series has been
