yeah rust is a problem. my whole shop is 3/4 galvanized pipe and i have never once had an issue with particles in the airstream. my buddy has that flexible piping system for compressed air. i think northern has the kits. he loves that stuff. not cheap though but easy to run.

Yeah I have a friend that owns a local body shop and he used the flexible piping. I believe it is made by RapidAir maybe. But I had mentioned ripping my black iron out and replacing with something better like copper and he had very high praises on the flexible piping. He says he will never use anything else.

I did quite a bit of research before piping my system last year. PEX came out as the best choice for me.

I’m using the same copper pipe and fittings I installed in my shop in 2006. Removed it when we moved in 2015 and installed in the new shop.

Which type of copper are you guys using? L or M? I see where some people say it doesn't matter which type to use and some people say it does. Just curious what you are using on your end.

use stick pipe not coil . coil is lower pressure . i plan on replumbing my shop this year . not sure on product yet , likely the flex . copper is high as hell right now . 1.64 per ft . type l is 2.24 per ft .
type l is thicker wall . type m is fine for air service .

Anyone ever thought of epoxying after w&g the inside of a brand new steel comp tank?
Dump some in, roll it around, or a cavity spray hose?
Leave it in sun for a week? I say it'd be a good.

to epoxy line just a motorcycle fuel tank correctly is a major pia. i could not imagine doing an 80gal compressor tank. needs to be acid etched, neutralized, flushed with water then the moisture flushed with acetone then epoxy lined with an epoxy tank sealer. i think i would just make sure i had an electronic auto drain on the tank instead and it should give you decades of use without lining it.

I think the inside of a new tank would be very smooth and oily. Not something even SPI epoxy could be asked to stick to after a mere rinse ,

Pulled iron pipes and just as I suspected they were full of rust. Ended up going with 3/4 copper and shark bite fittings. I have a HF air dryer. How far do y’all recommend for the air dryer to be from compressor? Is 20 ft of copper enough between compressor and dryer?
