The PVP Conference of the ASME (American Society of Mechanical Engineers) offers an international platform, which this year brought together over 750 participants from industry and research from over 40 countries who contributed about 600 lectures in total. The focus of the conference is to exchange experiences and ideas on current technologies and research in the wide-ranging field of pressure vessels and piping. Christoph Weigel and Emil Schwarz presented the experimental implementation and simulative description of selective initiator dosing in the working group's laboratory multi-zone autoclave. Daniel Dyck presented the latest results from the field of safety engineering. The following presentations were contributed to the ASME PVP 2025 session “Structures under Extreme Loading Conditions”:

• Investigation and Modeling of the Single- and Two-Phase Flow in High-Pressure Relief Systems, Daniel Dyck, Markus Busch
• Modeling Low-Density Polyethylene Polymerization in a Multizone-Autoclave using Coupled Computational Fluid Dynamics and Monte-Carlo Simulation, Emil Schwarz, Christoph Weigel, Markus Busch
• Impact of Initiators on Polyethylene Synthesis in a High-Pressure Multizone Autoclave, Christoph Weigel, Markus Busch
