6th Bregenzer Rohrleitungstage und Fachausstellung des brbv
The 6th Bregenzer Rohrleitungstage und Fachausstellung focused on the trenchless installation of PE pipes, emphasizing the importance of pipe quality. This event provides professionals with a platform to exchange knowledge and experiences in plastic pipe technology, contributing to the advancement of this critical infrastructure.
Sandbettlose Verlegung von PE-Rohren - Eine Frage der Rohrqualität
Over the past 30 years, the long-term strength behavior of polyethylene has improved due to advancements in raw material development. This raises the critical question of whether underground polyethylene pipes still require sand bedding. Current studies aim to determine the minimum quality level that allows for the elimination of sand bedding; some pipe qualities available on the market already meet this standard.
7th Wiesbadener Kunststoffrohrtage (Wiesbaden Plastic Pipe Days)
The 7th Wiesbadener Kunststoffrohrtage (Wiesbaden Plastic Pipe Days) took place on April 23 and 24, 2003, where Dr. J. Hessel presented a lecture titled “Long-term Studies on Welded PE 100 Pipes - Heating Element Butt and Heating Coil Welds.” This lecture focused on long-term investigations assessing the weld quality of PE 100 pipes, specifically regarding heating element butt and heating coil welds. The event served as a platform for the exchange of knowledge and experiences in the field of plastic pipe technology.
Long-term performance of infrared welded PVDF and PP Piping systems
Studies indicate that the long-term weld factor for PVDF-IR and HS welds can be set above 0.8. They also emphasize the importance of effective time-dependent behavior for the service life and safety of the weld connection. Infrared heating element butt welding has proven to be a technologically superior method, resulting in improved weld seam quality and has been successfully employed for about ten years for both PVDF and PP pipes.
6th Wiesbadener Kunststoffrohrtage 2002
Dr. J. Hessel presented a lecture titled "100 Jahre Lebensdauer von abgequetschten PE-Rohren - Eine Frage der Werkstoffqualität". This presentation discussed the long-term service life of crimped PE pipes, highlighting the importance of material quality. The Plastic Pipe Days serve as a platform for knowledge exchange and the advancement of plastic pipe technology.
