I hope this isn't too stupid a question but I'm not much of a piping specialist!
I need to sample off a 2" schedule 80 pipeline which may or may not be fully-flooded. This pilotng facility is yet to be built and I can pretty much dictate the sample point design. My initial thoughts were to use 1/4" Male NPT bored through fittings and insert a quill-type 45 degree insert facing into the direction of the flow. I was intending to have the guys just drill 1/4" NPT Female threaded holes in the pipe and screw the fittings into this because of the largish pipe wall thickness but even then I think the thread on the bored through male fittings will be too long and enter the flow which I really want/need to avoid. I'm also not sure about what sort of seal we'll get due to the rounded surface.
Does anyone have any ideas on how they would do this? Can we drill a 1/4" hole in the pipe and weld a female fitting to the outside for example? As I'm completely new to this I'm just not sure what's actually feasible.
Also, if we wanted to take a vertical 'slice' of this fluid, rather than a central tapping, do people know of any sampling devices we may be able to use?
Thanks very much for any info or advice!
