Drive-Couplings when setting a Sand-Point?

Sir:
All literature that I've read says to use Drive-Couplings when setting a Sand-Point. A Drive-Coupling has a Straight-Thread, (NPSC) or the likes. It states that the 2" 11 1/2 thread, (NPT) is to be screwed into the Drive-Coupling to the point of the 2 sections of pipe Butting up against one another, thereby not putting any pressure on the threads while driving, but rather the pressure would be against pipe-end
on pipe-end. My problem: I tried doing so. The NPT thread will not Butt within the Drive-Coupling
no matter how much power applied.

The only way that I could accomplish Butting the 2 sections together, within a Drive-
Coupling, was to Thread each section a full 2" of threads.

My question to you, Please!

What would you suggest that I do here? Is it advisable to do the 2" of thread onto each section of pipe?

Thaank you,

T Engelhard

Thread the pipes as much as required so that when screwed in they butt against each other. It will require more threads than a standard pipe connection.

Where are you driving your well? I have been trying to decide between driving or jetting a well at a remote cabin site. I'm in south Alabama and the site is on a bluff overlooking a river and swamp. I'm having trouble figuring whether their is water beneath the bluff within suction depth. I may move down the bluff a short piece to get closer to river level.

Best wishes,
Ed
