Thanks to their special manufacturing method, high-pressure lines from Poppe + Potthoff are considered to be very safe. The diesel injection technology has accompanied the family-run business, which was founded in 1928 in Werther (Germany), for more than 40 years. With high-carbon steels E 355, PP 600 and the newly developed PP 1000, three high-strength standard materials are available for high-performance lines. The autofrettage systems and test benches specifically developed by the engineering company Poppe + Potthoff Maschinenbau GmbH ensure the fatigue strength of the high-pressure lines.
From customer-specific solutions up to series production
The experts for high-pressure tubes are leaders when it comes to improving engines for performance and low emissions – whether for building cars, commercial vehicles or ships. The technology centre, close to the precision steel tube mill in Werther, develops customer-specific solutions, for example double-walled common rail systems for ships. Prototypes can be made here in just a few days and validated like in series production.
In addition, an integrated manufacturing plant was constructed in Ajka in Hungary in 2013. High-strength tubes are drawn here and processed into components under one roof. The flexible processes that are optimised throughout meet the highest requirements of cleanliness in accordance with the 0 ppm targets. Common rails and diesel injection lines are manufactured in series here for system pressures up to 3000 bar and beyond.
