I have a basic question regarding modeling piping in a compressor station.
Typically, the compressor is installed first and properly levelled and grouted. The pipe (discharge and suction) is installed next and all adjustments to the piping are performed until the mating faces of the pipes and the compressor nozzles are accurately aligned. At this point all the gravity load from the empty pipe is carried by the supports on the pipes and no load is transferred to compressor nozzle. After assuring that the pipe and the nozzles are accurately aligned, the pipe is connecetd to the compressor nozzles. At this instant no load from the pipe is carried by the compressor nozzle. When the system is in operation the compressor nozzle will be subjected to all the loads (temperature, pressure, gas in the pipe) that occur in the system subsequent to the initial connection bewteen the pipe and the nozzle. How is this scenario correctly modeled so that when the reactions are printed, it will show zero reactions at the compressor nozzle? Thanks.
How you add anchor at the entrance of the hot equipment when stress between anchor and equipment cause dramatic forces on the nozzle. the thermal stress is not depend on the length
Designers and engineers are amazing people. When they put their minds to work the results can be breath taken. Therefore it is not for Bentley to say how to install an anchor, but if one was installed on the suction / discharge nozzles, one can easily model that in AutoPIPE with results as Karim mentioned.
