Underground Transition piece locate
Underground Transition piece locate
(OP)
Hi Everyone,
Looking for some creative ideas for locating an underground 10" to 12" transition piece on a sour gas pipeline that is unpiggable. I'd prefer not opening up the line for a tethered tool or taking it out of service. I'm looking for as built records, old hands that were around at the time of construction, but not much is turning up. My thoughts were to hire a dowser to locate the transition and then bring in the hydrovac. Any other ideas? Any thoughts or experience with using dowsers for this kind of thing?
Thanks!

You can locate the line by Dousing but you won't be able to locate the transition. Dousing looks at the impact a large metal object has on the magnetic field of the earth, the size transtion will not show up. What about looking at how many feet of each size of pipe were ordered for the project and calculating the transition general area from that?
The radar might work if it is not buried too deep. I don't have any idea what "too deep" is before you ask.
Goodluck

(R10)(L10) + R12(L12) = RTotal , and L10 + L12 = LTotal

When all else fails, I suggest a shovel and a binary search.

I sure like rconner's idea as well.
