2nd Internationale Fachtagung - Kunststoffe im Anlagenbau
At the 2nd Internationalen Fachtagung "Kunststoffe im Anlagenbau" (International Conference "Plastics in Plant Engineering") in Munich, Dr. J. Hessel presented on the calculation of the remaining service life of polyethylene pipes after long-term use.
Cost- and time-saving method for generating creep curves for plastic pipes.
The strength-related design of plastic structures is typically conducted using creep rupture curves. This article describes a testing method for generating reliable creep curves for thermoplastic pipes, aimed at reducing uncertainties in calculating the minimum stress over a 50-year lifespan.
Sewerage And Drainage Pipe 2009, Köln, Deutschland
The conference covered key topics related to plastic pipe connections, including a presentation on the material requirements for PE pipes used in the relining of sewer pipes. J. Grieser’s talk focused on the challenges associated with stress-cracking substances.
Plastics Pressure Pipes Conference 2009, Köln, Deutschland
The conference focused on the design and calculation of PE 100-RC pipes for gas and water pipelines, emphasizing a minimum service life of 100 years. The presentation by S. Nonhoff and Dr. J. Hessel highlighted the specific requirements and durability of these pipes.
Jornada Técnica: Tuberias de Polietileno (PE), Barcelona, Espana, 28 de Mayo 2009
The event focused on the examination of welded joints in polyethylene pipes. Dr. J. Hessel discussed various testing methods, including bending, tensile, creep, peel tests, and macroscopic examination
