Considering the effect of the interaction between piping and support systems in the piping design is a more integrated process for improving the safety of piping systems. A special load case for piping systems are forces induced by gas detonation or deflagration in the pipes. A report is given on the research work to determine fluid/gas induced time dependent forces. The effect of explosion wave front velocities between 1200 m/s and 2000 m/s was investigated. The reason for this study was to demonstrate the safety of this existing pipe system. A full dynamic analysis of a pipe system was performed with regard to the elasticity of pipes and support-frameworks. The results of the finite element calculations of a large acetylene pipe system in a chemical plant will be presented. A reduction in the support forces of up to a factor of 4 was achieved in relation to conventional calculation methods.
