Dear JV,
Back to theory of expansion, which element (pressure or temperature or both pressure and temperature) is the reason to make expansion displacment at end of pipeline-goose neck?
Last time I calculate the displacement at end of pipeline (pipeline-gooseneck) by taking into account pressure and temperature, and the results the displacment is 677 mm.
However, i just think again, i realize pressure do not effect the end-cap force at end of pipeline (connection pipeline-gooseneck) because the pipeline and gooseneck is just create a 15 deg, not 90 deg when we assume to calculate in expansion calculation.
If i consider the thermal displacment affect by only temperature, the displacemnt at the end of pipeline only 30 mm and when i check in Autopipe, it not over stress.

Could you advice me about the expansion?

Thanks and Regards,
Steven
