I would like to know what the actual OD is of schedule 40 PVC tubing.
I am building a NVIS dipole for 3.6 & 7.2 Mhz
I know what the wall thickness is and the nominal size, but say for instance
the OD of 1 1/2" schedule 40, is it really the OD they are measuring?

Here in Australia we have a quaint method of measuring structural steel pipe
where the OD is nothing like the size its listed at.

For example 3/4" pipe is actually 1 1/16 OD!! Give or take the wall
thickness, but its still known as 3/4" pipe!


Thanks

....scroll down a little less than half way. It turns out it's the same
OD as steel pipe of the same size.

There's a short but interesting story behind that on the link above.

You might try venturing out to your local hardware, plumbing, or DIY
store with a ruler. It's less convenient than surfing the Internet, but
there's no problem with finding the right URL. All you have to find is
the pipe.

Thanks Roy and those who have responded.
I did just that, I found a willing assistant who cut off some pieces for me
and after measuring them I found that our Series 1PVC is equivalent to the
USA std of Schedule 40.
Regards,
John
