I have an application about the restriction orifice plate installed in the 8" (schedule 80S) cryogenic LNG pipe line for reducing the pressure (inlet pressure= 94 kg/cm2G, and pressure loss required is 13.5 kg/cm2G) based on the flow rate 120 ton/hr, -152 degreeC LNG liquid fluid. I got the calculated bore diameter is 44.65 mm with pipe inside diameter 193.68mm (beta ratio =0.23056), and the plate thickness will be 37mm. But I need to know which shape is better for this application, square edge type or bevel edge type (as like traditional orifice plate for metering)?
Any critical items shall be considered in this application?
