What's a good semi-rigid flexible tubing for permanent outdoor use?

Need a better picture; closer in.

I want to finish the wall inside the building and hence need the LB mounted.

How do you keep frost from pushing your piping around?

I'm not going under ground because (pictures attached) I would have to trench around my garage and my septic tanks which adds a lot of distance (copper (money)) to the bill. Also I would have to rent a trencher, which would consume a day of man-hours just to go get it, offload, cleanup, onload, and return, not to mention the man-hours spent actually digging that winding trench or the rental fee ...or the risk of hitting my septic lines and incurring more cost. I'll be taking the power off the side of my house, running it through the attic and coming out at the opposite peak (18ft high), over the top of my driveway across a 64ft span with a 22ft high pole in the middle, and down to my barn (14ft high). There will be plenty of room to get vehicles under it.

You can see the sharp bend made by the carrier cable at the top of the pole; Whatever I use has to be able to make that bend and it's not any kind of standard angle that they make a pipe fitting for. Although I suppose any angle is possible with 2 90's and a nipple. The carrier cables are taut right now but I expect there will be some droop once I hang the heavy copper cable off it. That's why I wasn't considering metal (esp copper). This will be blowing in the wind so I don't want it developing cracks from fatigue.

I understand better what your challenges are. With the wire as high as you're putting it, I would think you should be able to just run SE cable (Service Entrance cable) I'm not a licensed electrician, but I think the SE cable is rated for UV exposure and you wouldn't need any conduit for it, just tie it to the carrier and it'd turn the corners how ever they need to be. I've never used that black poly pipe, but that sounds like a soloution for the water. For an air line there is a product from Rapid Air Compressed Air Distribution System | Rapidair | Engineered Specialties where you can get up to a 300' coil that appears to be outdoor rated (I've not checked it out). But do you really need an air line? Why not use 2 compressors or a portable compressor? It might be cheaper.

Running air lines all over the place also makes for nice additional storage capacity.

I second the two compressors solution for the air.

It's also an issue of noise. I have One Big Devilbis compressor running in a heated upstairs room of the barn. I don't have to listen to a compressor anywhere!

Why not get a separate electrical service at the barn?

I have a 500 gallon tank hooked to mine, compressor doesn’t run too much

Absolutely - a second air compressor would be prudent. BUT - he still has the water line problem to contend with.

I had a similar situation to deal with. Went with a second air compressor, and CAREFULLY laid a water line from source to the shop. I also installed a cutoff from the source to easily drain the water line to the shop in event of freezing weather.

I currently have a separate electrical service at the barn.



The power company is screwing me ultra hard on that deal (separate thread on that) so I'm going to disconnect service and tie in with my house power. That's the reason why the service entry on the barn is on the far side. I installed it closest to the existing transformer pole so as to give the linemen for the soulless utility an easy day; in the end I just made things much harder for myself.
