Calculation of LNG pipeline diameter
Thread Content
I would like to ask the experienced colleagues how to calculate the diameter of LNG process pipelines at different flow rates. It would be great if there is a relevant standard or a specific formula for this purpose. Thank you
Calculate the diameter using 7 m/s.
The pipe diameter is mainly calculated based on the flow velocity; the flow velocity for LNG process pipelines is generally set at 1.2 m/s.
LNG has flow rates and pressure drops associated with its movement; for process pipelines, a flow rate of 7 meters per second is generally adopted, with a maximum pressure drop of 30 KPA corresponding to 100 meters. There are also requirements for the inlet and outlet flow velocities of the pump.
