    ASME MFC-3M

    Hello, Can anyone give me an opinion on the straight lengths of pipe required in Table 2 for a natural gas orifice metering run? Immediately upstream is a filter (not covered by table 2). I assumed there would be no swirl in the flow coming out of the filter. Thoughts? The line diameter is...

    gas pipe velocities, erosion and sound pressure level

    Hello, I have a gas pipe orifice metering tube that measures 6 in OD schedule 40. I am review the orifice size and resulting piping velocities. Does anyone know any velocity limits? I calculate velocities at the orifice around 163 Ft/sec. 60 Ft/Sec in the pipe. Does anyone have a...

    Gas pipeline velocity and sound pressure level

    Hello, I have a gas pipe orifice metering tube that measures 6 in OD schedule 40 with a 3.6 in orifice. I calculate velocities at the orifice around 163 Ft/sec. Does anyone have a correlation on what sound pressure level that might produce? Are there limits for erosion? Thanks Ken
