Gas pex question

I have electricity (3 #6 wires) running through a 100' / 2" conduit from my house to the barn. I used 2" conduit because it was actually cheaper than 1" conduit. Must have been store inventory issues...

Anyway, since installing the electricity, I wish I'd have installed natural gas to the barn as well, and I got to looking at my very large electrical conduit. The 2" diameter would allow me to run a 1" gas pex line in the same conduit, which would spare me the mess of digging a new trench.

Any comments on that? Are there significant risks to having direct burial pex inside the same conduit as electric?

Okay...
It's time for you to call a plumber....

I'm in no way an authority on the subject, but (1) I seriously doubt if you can run a gas line of any kind in the same conduit as electricity, and (2) you probably can't buy much less legally install the gas line yourself. Do as Redwood suggests, call a plumber.

NO and Absoutly NOT

Can not use pex for gas.... EVER
Can not run gas and power in the same chase either

well, perhaps it's a bad idea to run gas & electric together. Maybe so...it's what I was asking.

But I've seen with my own two eyes yellow pex that says "gas pipe right on the side, so I don't know why a plumber would say:

Can not use pex for gas.... EVER

Again, I'm not an authority, but I am pretty sure the yellow pipe you saw is not Pex. There is a gas piping that is yellow, but it is my understanding that it can only be sold to licensed plumbing contractors. Hate to rain on your parade, but I think you will have to get a licensed plumber to buy and install your gas line in a new trench. One good thing is if you ever have to run a new wire, you have plenty of room to do it in that 2" conduit.

Sounds like a plumber is the way to go. Thanks for your help and explanation on the pex.

If you fill a pipe with leaking gas, and then ignite with an electrical spark, imagine the explosion.
Kind of like those natural gas explosions they do in movies.

The gas company does a plastic or PEX line, I don't know what they are made of, but they make them up without fittings, and they go in their own ditch.
You never see the plastic above ground. They come up with metal.

A funny story about cleaning painting equipment in a garage.
The garage door was closed, and the painter was cleaning his tools after a days job.
He plugged in his cord, and it sparked as he pushed it into the outlet.
He was blown through the door and covered in burns.

Okay, maybe not funny.

Get the fuel/air mixture just right, and lots of common stuff will blow up. It's never good to deal with flammable stuff in a closed room - sometimes even a static spark is all it takes if the mixture is right. Couple of days ago, a truck was carrying spray cans of paint and had a leaking oxygen cylinder (and obviously something else) - caught fire on the interstate and made a big mess of traffic...luckily, they saw the smoke and got out.
