Hi All,
We are currently working on a plastic piping project in which I used ROHR2 to perform stress analysis on the piping system, evaluate support loads, and calculate nozzle loads.
This project requires the inclusion of seismic parameters. Based on the nozzle load limits provided by the customer, the calculated nozzle loads under the Operation Hot load case (normal operating pressure and temperature) are within the acceptable range. However, under the Seismic load case, the nozzle loads exceed the customer’s allowable limits.
I would like to ask regarding nozzle load evaluation:
Should seismic parameters be included in the calculation of nozzle loads?
Or are there separate standards or criteria specifically for assessing occasional loads such as seismic or wind?
Thanks
