    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

    The operating conditions are about 380 psig static pressure at 60 to 80 F. That was a beta ratio of 0.6. Thanks for the comment.

    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
