About 200 visitors from 35 different countries took advantage of the opportunity to learn firsthand about the subject "tubes for hot water" in a two-day symposium held last December by cincinnati extrusion gmbh, Vienna. Along with collaborating companies, Akzo Nobel, Borealis, Dow, Graewe, Nexans, LK Pex AB and Solvay Padanaplast.
During the Symposium, after a general introduction to the market of hot water, the participating companies reported on the cross-linking peroxídica of tubes of PEX-a, on PE-RT, a new material for pipes for hot and cold water applications, as well as the particularities and the possibilities for application of tubes of PEX-b. Also be talked in a theoretical way on the production of tubes of PEX-a high qualitative value in extrusion of double spindle machines with cross-linking go online, before moving on to a practical demonstration with tubes of dimensions between 63 and 160 mm.
Machine manufacturer gave the visitors an overview of the different variants of tubes and, at the same time, on the wide-ranging specialist Cincinnati Extrusion machines, and did so through the presentation of four lines for tubes in operation, in its technical centre. Among others, showed a tube made of plastic and aluminum production: first was a tube of PP-R in an extruder high performance of the latest generation of 37D single model monkeys 60 G, tube that was reinforced in line with a band of aluminium coated of adhesivebefore being coated, also online, with a layer of pp. Furthermore, in Vienna was a PE-RT pipe production coextruded of two layers with strips of colours, as well as the manufacture of a tube of five layers of PEX-b, with the oxygen of EVOH barrier layer.
Five layers tube extrusion line was equipped with two extruders single Talos 60 - 30 G for the layers internal and external, as well as with three coextrusoras model 30 CE to the layers of the adhesive and the EVOH, and a distributor of quintuple spiral mandrel head.
