Long-term behavior of welded joints in large-diameter polyethylene pipes
The development of large-diameter polyethylene pipes and their butt-welding technology requires new testing approaches. With adapted testing methods, creep rupture tests can now be performed on wall thicknesses up to 120 mm, using fewer samples and accounting for the typical fracture behavior of PE welds.
Sewerage And Drainage Pipes, Düsseldorf, Deutschland
The conference in Düsseldorf covered key topics in the plastic pipe industry, featuring an outstanding presentation by Dipl.-Ing. S. Nonhoff on the long-term behavior of various polyethylene materials.
Second DVS/WJS Conference on Joining Plastics, Handwerkskammer Düsseldorf, Düsseldorf, Deutschland
The Second DVS/WJS Conference in Düsseldorf focused on key topics in plastic pipe connections, featuring a presentation by Dr. Hessel on accelerated testing methods for evaluating the long-term behavior of welded polyolefins.
Experiences in the Implementation of PAS 1075
The development of PE 100 materials has resulted in PE 100-RC, which is resistant to slow crack growth in accordance with PAS 1075. This specification details the dimensions, requirements, and testing protocols for PE 100-RC pipes used in alternative installation techniques. Experiences gained from implementing PAS 1075 address various questions related to these techniques.
14th Wiesbadener Kunststoffrohrtage (Wiesbaden Plastic Pipe Days)
At the 14th Wiesbadener Kunststoffrohrtage (Wiesbaden Plastic Pipe Days), Dr. J. Hessel presented on the mechanical and thermal limits of PE 100-RC, introducing new creep rupture curves and discussing enhancements in thermal aging for improved temperature resistance.
