Hey members of ARS! Today I got the standpipe for my thunderbolt, and found a place to get the flange. I just need to know now, does anyone know where I can get my pipe threaded? It is the only thing I need to get the thunderbolt on the blower and outside! Just PM me or comment if you know. Thanks, Nick

I would try a fire sprinkler contractor or commercial piping installer.

Also from my understanding some pluming/pipe supply companies will thread pipe.

Some machine shops could do it. Or maybe a hardware store if you're really lucky.

You'll need to go to a pipe supply or similar type of place like mentioned above. Did you get the flange at a pipe supply? Anyone else won't have a pipe thread machine big enough. When i got my flange at the pipe supply i took the cut off pipe with me and they threaded it for me.

The main deal here is most all pipe threaders go up to 2", or 2-1/2"-4". Regular hardware stores don't sell pipe larger than 2" so don't have threading equipment for anything larger. So you would need to find a place that works with or sells pipe in that larger size range. Another possible option would be electrical contractors, (I believe ridgid conduit is threaded the same profile as pipe).
