Extrusion International 5-2025

56 Extrusion International 5/2025 PIPE EXTRUSION – CASE STUDY First Projects with Record- Breaking Large-Diameter Pipe Lines Successfully Implemented in Egypt Precision in large-diameter pipes saves up to 1 million euros in material costs Only 5 mm wall thickness deviation with a pipe diameter of 2.7 m Extrusion technology from battenfeld-cincinnati makes it possible. After all, there is no other machine manufacturer in the world that has so much in the design of complete large-diameter pipe extrusion lines and has installed as many lines internationally as the German-Austrian company. The most recent record-breaking lines for large PE pipes up to 2,7 m in diameter were recently installed at two customers in Egypt and are running to the customer's satisfaction. The rst projects have already been implemented. “The quality and precision of the large-diameter pipes we achieve on the new line from battenfeld-cin- cinnati is excellent,” says Ahmed El Mahalawy, owner of Plastic Pipes & Products Co. (PPP) in Cairo, praising the supplier of the new complete line. The Egyptian pipe manufactur- er PPP has just completed a project with large-diameter pipes in Oman: high-quality pipes transport seawa - ter to a desalination plant - an ideal application for plastic pipes, which score points here with their corro- sion resistance. It is also an ideal ap- plication for large-diameter pipes, as large quantities of water can be transported ef ciently in the short - est possible time. It is usually the material costs that enable the most money to be saved in the production of large-diameter pipes. “The main focus of our tech- nology lies in the reduction of wall thickness tolerances. Thanks to nu- merous optimizations of the indi- vidual components of the system, we can now easily achieve values that correspond to half the DIN standard,” explains Andreas Türk, Sales Director at battenfeld-cincin- nati. The dimensional accuracy and minimized wall thickness deviations alone mean that one line can save more than 1 million euros in raw material costs per year compared to conventional lines and deviations. “Further advantages of our tech- nology are the high output rates of two tons and more per hour, the lifespan of our systems, which are designed for 20 to 25 years, and their low energy consumption. This means that an investment pays for itself within a very short time,” says Andreas Türk. The bene ts described are based on the process engineering design of the overall system, in which all individual components are perfect- ly coordinated, and a modern and intuitive control system ensures reliable inputs and con gurations. The melt temperature plays a major role in the extrusion of large-diam- eter pipes, as this is the main cause of unwanted sagging. Andreas
