Hello everyone. I searched my issue in this forum and other place. But I could not find a satisfactory answer.


Pipe is 48" and connected to top of vent nozzle of the vessel. I supported pipe near to top with hanger. Hanger node is 280 and CNode is 281. A weightless rigid connect to node 281 from the center of the vessel. I applied this method to all supports. But I confused. Whole vertical pipe is moving to up along with vessel. Does it true?
