Lead Pipe Strength?

[Jolly Roger bus 223]

Never said that you would run liquids in conduit?
I wanted and didn't say that any pipe ran whether conduit or water pipe can be used to run wire as long as you don't expect to put water in it. Regardless of the type of pipe?
We don't usually use ridgid in the ground around in my area because of the salt water tables. They use PVC sized accordingly and encased in concrete/duct bank to each pull station and only come out of the slab with ridgid

What did I say that was not true?
I never said what he wants to use will not work, probably will easily. I'm just stating that those parts were not made to support a couple thousand pounds the way a deck and occupants will subject it to. Those fittings in the intended application have no tension on them.
If I was a pipe layer and had tons of those fittings laying around I would use them. I'm not and therefore I would weld up some steel to do the job.

To make this simple, rigid of whatever size he chooses has the inherent strength to work if he decides to use it. No sense arguing with you, been at the game too long. What have you built with rigid conduit?

When was the last time you build a heavy deck with capability to sustain another 1000lbs on it with 3/4" rigid fittings? You're preaching to the choir now, show me where I said it won't work and I'll show you where I said it would be fine.

Maybe take this to another forum ... guys?

Too bad Unistrut isn't strong enough.

[bubb, the real one]

I made a full length roof rack, used 2in square tube 42in long for the vertical beam and same tube for the 8ft long horizontal pieces, when I hopped on the horizontal piece it bent about a quarter inch,
I did a vertical piece between each window, I put two 3/8 inch bolts to hold each vertical piece to the frame between the windows, the pieces came down about 14in below the window gutter. I used a single 3/8in bolt to connect the horizontal piece to the right and left side vertical beams.
I bolted roofing sheet metal to the 44in long side beams to keep the sun off of the side of the bus.
The roof rack extends an extra foot from the front and back of the roof to protect the lights from branches.
The tube is probable 1/8th thick, again, get an 8ft piece and jump on it to test its strength.
