    Bent Orifice Plates

    Is there a correlation that can determine the error in an orifice plate reading after it has warped? For example, if I use an orifice plate to measure steam, then syrup (or heavy crude) and the viscosity of the syrup warps the plate, is there a method to determine that the flow rate is within...

    AGA 3 / API 14.3 Basic Question

    What is the difference between AGA 3 and API 14.3? After reading the "Scope" section, it seems that they are pretty much the same. I was told (by a vendor) that the difference is that AGA 3 is for custody transfer and API 14.3 is for non custody transfer. Any insights? "If experience...

    6010 by 7018 vs 6010/6010

    I am being asked to compare the lifespan of a 6010 x 7018 weld with a 6010 x 6010 weld in a pipe that will thermally cycle once every other week. Where is a good starting place for evaluating the two weld types? "If experience was always the only factor, how would we get to the moon?"...

    Non intrusive flow meter

    I have an application where my client is looking to meter his gross production in a heavy oil field (API 13). Initially, he started with a Vortex meter but the rubbers from the Sucker Rod Pumps are coming down the line and plugging it up. When its plugged, it caused the stuffing boxes upstream...

    Slip On Flanges in Steam Service

    I have a client requesting slip on flanges for a steam application. I have another client who is adamant that this poses a safety concern and will only accept butt or socket type connections in steam service (ANSI 1500). I've tried to get a full answer to why this is but I cannot get a...

    Belleville Washers in Steam Applications

    Our client has requested that Belleville washers be used on their flanges for steam applications. Their reasoning is that improper torquing practices can cause the flanges to leak. I am sure this has been done and I've seen discussions on this board regarding this and have read the white...
