Extra-thick large-diameter pipes connecting Europe with Asia

high-speed extruder. With a processing unit that has been extended to 37 D, Monos extruders reach a 30% higher output than their predecessor models from the Proton series, so that the extruder model can be scaled down by one size to produce the same output, as in this case. Firat was reportedly pleased with both the high productivity of the two extrusion lines and the quality of the pipes, which show narrow thickness tolerances and fully comply with all specifications.

The extrusion dies as well as the downstream aggregates were adapted to handle the special dimensions. The PHPO 100 and PHPO 63 pipe extrusion dies equipped with spiral mandrel distributors anddie-face cooling ensure optimal melt temperatures and an excellent melt distribution, even with the high viscosity of PE 100. Thanks to a modification using special die and mandrel components, the wall thickness of 109.1mm in the 1,200mm pipes could be produced without any problems. Both lines, with an output of 1,000kg/h each, operated round the clock for a whole month to have the 4,000m of large-diameter pipe delivered on time. One line is equipped with a Proton 150-30 G single-screw extruder, and the second line features a Monos 120-37 G

For the government project of laying a water pipeline through the Bosporus, Firat Plastik Kaucuk Sanayi ve Ticaret AS, Turkey, recently produced 4,000m of large-diameter pipe within record time. 300,000 cubic metres of drinking water are to be transported daily from the Ömerli reservoir on the Asian side of Istanbul to the European part of the city. The pipes have 109.1mm thick walls – the highest wall thickness so far produced – to enable them to withstand the high pressures of the water flowing through and the surrounding water. For the production of large-diameter pipes, each 13m long and weighing 5 tons, the Turkish pipe manufacturer relied on its long-term supplier, Cincinnati Extrusion GmbH, Austria, who simultaneously remodelled two extrusion lines on-site.
