Plastics machinery specialist, Krauss Maffei Extrusion of Munich Germany has developed a special system technology for the production of PE-Xa pipes for heating systems and gas transmission.
The new pipe extrusion systems utilise peroxide crosslinked technology for polyethylene pipes supplied under an exclusive partnership agreement with Crosslink Finland OY, a leading manufacturer of infrared crosslinking ovens.
Featuring a specially developed twin-screw extruder with a conical processing unit and pipe head as well as a unique calibration and cooling system, the complete line is ideal for the processing of the ready-mixed compound consisting of polyethylene, a stabiliser and peroxide.
Once the three components are mixed, a diffusion process takes place and the liquid peroxide is absorbed by the granulated polyethylene, producing an extremely homogeneous material mixture.
The new pipe extruders provide a high degree of reliability and constant process conditions, which ensures a high quality product with a consistently high degree of cross linking.
The crosslinking of the PE pipes takes place in-line in the specially developed infrared crosslinking oven supplied by partner Crosslink Finland OY, which has been integrated into the Krauss Maffei solution. This approach eliminates the need for additional downstream production steps and reduces manufacturing costs.
High flexibility as well as high resistance to heat and cracking are some of the benefits of the crosslinked PE-Xa pipes. The pipes are typically used in panel and radiator heating systems as well as in the supply of hot water systems, drinking water, compressed air and gas lines.
