Copper is great. It cools the air quickly so it turns the water vapor back to water so you can filter it out and it's super clean. I'll be using it in my shop!So I'm old-fashioned. Sue me
I don't use black pipe because I don't want flecks of rust traveling through the system; PVC is a shrapnel bomb waiting to happen.
What would you use in your "modern" shop?
My son just got a quote for work on his double garage. Insulate,vapour barrier and sheet with aspenite. $5700. outside house wrap and metal siding. 7500. Aparrently contractor labour has gone up too. Bet his workers get paid typical crap wages though.
sheet of aspenite 15 years ago was $8/sheet. Today its $32.
I bought a couple sheets last year,$15.
Yes,canuckistanian funds.Since you used labour instead of labor am I correct for assumed the “$” was Canadian maple bucks and not American freedom dollars?
You should braze the lines. If you have a tig welder you could practice some welding on them if you have the time.I've been wanting to run copper lines in my garage for my compressor. Just haven't gotten around to it yet.
I was all ready to go and plumb it, but I have a cousin in industrial maintenance that at the time said to wait, the price of copper was coming down at the time and was really gonna plummet. Wait till it does.well, still waiting.
My compressor is a 5hp 80 gallon 2 stage upright, cuts off at 175 psi. I figured I would run up the wall from the compressor along the ceiling, down the 36' (long) side, then across 15' above the garage door to the center, and back down the center pier between the two overhead doors/ also across the back to center / with drops at front, back, 1 approx center along the long side wall, and 1 in the front corner for the blast cabinet.
I'm also looking for a deal on a refrigerated air drier at a cheap price, would be the 1st thing the air would pass thru once it leaves the air tank. I found a couple at an industrial supply place (used) for a decent price, but the cfm rating is about 60% of my compressors rated output so I'm still looking.
Related; what's the difference between cfm and scfm ratings? My unit is rated 17.some (almost 18) cfm at 175 psi. The drier I found is rated for 10 SCFM.
Yeah I have brazed plenty of sheet metal (steel) over the years, none recently though. Never tried to braze any other type of metal.
I know that with copper there is a type k,L and M kind of like pvc or steel with the different schedules, (40, 80, 120) for different pressure ratings, but are there different fittings L,T, cross, etc for higher pressure copper?
I too have run normal fittings but I was just curious if they made something heavy wall.The OD on K, L and M are all the same. It's the ID that gets slightly smaller with the thicker wall. Don't use the M, it's about as thick as tinfoil.
I haven't seen any thick-wall fittings but then I didn't worry about it. The "normal" plumbing and big-box store fittings are fine!
I have run my (soldered) 1" type L system at 140 psi for years with no problems.
As noted earlier in the thread, you get little flakes of zinc coming off and messing with the seals in your air tools. Then you also get little flakes of rust...Is galvanized a decent choice??
