Compressed Air Piping

[olredalert]

----Not kosher, but when I built my cave we buried the lines in the walls. My suggestion is that if you have anything behind a wall be sure to triple test the system. I now have to shut off mine at night, which isn't too big a deal. I have so much crap in front of the walls that I just can't imagine trying to fix the minor leak I have. If I forget it takes several hours to blead down....Bill S

I used the Rapid Air Rapid Pipe (aluminum pipe) about 5 years ago. I'm really happy with the product. I myself would be a bit skeptical about being sandwiched in the wall in the event of a leak or failure.

Nonetheless, the fittings were high quality and the system it easily added on to.

In my previous shop, I ran 50' of black iron on the ceiling, with 4 moisture drops and ball valves along the system. I don't see getting enough air to properly cool the pipe with long term use to condense the moisture out of the air enclosed in a ceiling/wall. When I ran my blast cabinet for a couple hours, I had moisture all the way to the 4th drop. In an 8 hour pressure pot blasting day, I had to stop halfway thru and let the pipe cool for an hour during lunch to prevent getting moisture in the sand.
