1-1/2 in. x 10 ft. 330-PSI Schedule 40 PVC DWV Plain End Pipe

Because the pipe itself is rated at 330 PSI, it can be used for compressed air as well as pressurized liquids, but the problem is finding pressure rated fittings in this size. Most of the time, Schedule-40 PVC fittings larger than 1 in are intended for use in DWV (drain/waste/vent) applications, and not guaranteed for ANY significant pressure AT ALL. This size of pipe would create a significant reservoir of high pressure air, just inside the pipe itself, which means you could assemble your system and have one of the fittings suddenly tear off of the pipe, and that would be REALLY DANGEROUS at 120 PSI (a normal compressed air supply pressure). If you want to save money on piping for compressed air, you might consider using 1/2 in Schedule 80 PVC (the grey stuff) and make sure that all the fittings are rated for at least your maximum supply pressure. Using a rated pressure vessel to store the air, and just running it to the quick connects using the PVC is an approach I've seen used before in various applications. Myself, I choose to run compressed air in 1/2 in sweat copper in order to be more confident that I won't have any blowouts, but it is significantly more expensive. Good luck.

Be sure to post video on the internet. That would be hilarious to watch. This will collapse, if you attempt to use as a polu vaulting pole...

I would say NO NO NO ! Are you trying to kill yourself ? Get a professional to install ANY natural gas lines.... DANGER!

Yes it must be secured propelly

Its rated for non-potable water.

Yes, this pipe is rated for both pressurized water (NSF-PW) and drain/waste/vent (NSF-DWV) applications, and has been tested for resistance to corrosion and other soil conditions. Just make sure the fittings and solvents are also properly rated.

Cut them your self bring a finished hand saw with you

depends on local home depot but typically $5 (ish)

Too many missing variables to give a definitive answer. It will bend, it may snap the pvc by the galloping of the string lights by wind. Personally I would recommend aluminum pipe for fencing. There are stronger and will hold up to wind. There are two places to look at Home Depot, one is in the lumber area and is 2 3/8 fence pipe. Two different heights the second place is in the electrical area in 2" conduit pipe. That is my reccomendations.

Since 108 inches is 9 feet, and these pipes are 10 feet long, you might have the associates at your HD cut it to length, and then you can buy the cut piece for the price of a full stick, which tends to be less than a custom length. Usually, the associates will be willing to cut the materials for no charge, but you might want to ask before you have him/her proceed. (Please review the other questions in this product line to see if this is the best material for your project.) Good luck.
