I've been using thinwall DWV plastic (Sch 30 or even 20) and excepting

I wrapped some wire around my planer discharge chute because of the
static. One end is grounded to the body of the planer. It helps quite a
bit.

Bill Pentz's site had a recommendation of putting a piece of metal tape
down the pipe on both inside and outside then connecting them with a
through bolt. Sounds like it worked well.

My hose is long enough that it is always in contact with the concrete
floor.
Braggit.

That contact seems to take care of static discharge as I can't
remember ever being shocked by the hose. A different climate might have
different results.
