Dear colleagues,

I am a salesman of a fabrication company. Company has lots of experience in fabrication of gas flares but the design capabilities leaves much to be desired.

The problem is. Wet natural gas in a pipeline from x-mas tree to an early gas facilities has a pressure of 120 bara. There will be emergency flares every 6-7 km. Time of pressure relief via burning gas in one section of a pipeline is about 15 minutes. Estimated tip diameter is 250 mm; stack height is 35 m. But engineers can not calculate wall thickness of a flare stack for such a valuable pressure because they even have no design model for that. Please support me with some information on this problem in order to estimate the thickness.

Thank you!
