Clearly above 3000 bar: Poppe + Potthoff sets standards in high-pressure tubes

Common rail system with diesel injection lines from Poppe + Potthoff

At the Tube trade fair, which will take place in Düsseldorf from April 7 to 11, 2014, the Poppe + Potthoff Group will set the focus on its range of products and services in high-pressure technology. The company's seamless precision steel tubes are used worldwide in hydraulic units, pressure test benches and injection systems for diesel engines. 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.
