You can bend conduit with an inexpensive tool. Conduit is much
lighter and cheaper than pipe.

Dan

Conduit is thin wall material. It cant be threaded with any
suitability. Its not designed to carry anything other than wire.



You are thinking EMT - electro-metalic tubing - not Rigid Conduit.

You are absolutely correct. I glossed over the first "rigid"
My appologies indeed.

A definate Brain Fart on my part.

Rigid conduit is thick, and is threaded for EVERY use.
1" rigid conduit is .126 inch wall. The thread is generally a straight
thread instead of a tapered thread on pipe.
1 inch Sched 40 iron pipe is .130" wall thickness.
2 inch rigid is .146 inch wall thickness, while sched 40 iron is .150
nominal thickness

Rigid steel conduit can be galvanized (in and out) electro galvanised
(outer only) with organic coated interior, or organic coated in and
out - and Rigid conduit can also be aluminum or stainless steel or red
brass.

RMC has a smoother interior than pipe - it is a rolled, electrically
welded seam tubing with uniform wall thickness and a defect free
interior surface - required for pulling wire.

Black Iron Pipe is made from ductile iron - not steel (generally
speaking).

Pipe is thick wall and is designed to be threaded and then threaded
into pipe fixtures...

Its capable of carrying significant pressures

The methodology of the left has always been:

1. Lie
2. Repeat the lie as many times as possible
3. Have as many people repeat the lie as often as possible
4. Eventually, the uninformed believe the lie
5. The lie will then be made into some form oflaw
6. Then everyone must conform to the lie
