My application was the same as yours - erect an irrigation pipe vertical.

It has the same sizing/threads as the threaded conduit at Home Depot - 
the type is IMC vs the thin wall not threaded EMT.  I think most larger 
commercial electrical suppliers will stock it.  I've seen it used in 
larger diameters for outdoor service and for larger sizes inside 
factories.  The threading is different than NPT pipe, it has no taper so 
it is easier to adjust a section to length.  However, this also weakens 
the joint a bit.

Grainger has it in their catalog, but you don't want to pay their price

Surplus/recycle electrical suppliers might be another good place to look.

Sounds like this material might work and not be so heavy.
