I have been searching for about 3 weeks now to find a place to sell a small amount (4 feet) of finned aluminum tubing with no luck what so ever. I have searched the entire internet over and nothing.
Does anyone know where to get some of this stuff? Anyone have some sitting around to sell?

 

you need a place that specializes in extrusions



this is an extrusion i was working with for a while and welding up one of the first ones above.

what size do you need? i used to work for a company that specialized in retubing heat exchangers, so i know where there is a ton of that ****.
it's not aluminum pipe though, usually either mild steel or stainless steel tubing. they strip the aluminum fins from the used stuff and sell it to recyclers, so i am sure i could get my paws on a small chunk of it for you if you wanted.

Not enough surface area on those types.

Do they ever get any all aluminum stuff? Kinda hard to weld stainless to aluminum.

This is the size I am looking for or very close to it for anyone that knows of some.



A (2) 13" or (1) 26"
B 1/2" - 5/8"
C (2) 12" or (1) 25"
D 1.5"
E 1/2" not very important

Minimum of 12 fins per inch, Embedded would be best but L foot or edge tension would be fine.

Nothing from the ones I've tried so far. There is a metal scrap yard about a half an hour from me that maybe just might have some but I doubt it. I have to pick up some plate from him anyhow for a welding table.

Nothing.....


Someone has to know something, this isn't nasa only parts or anything.

 

i don't think i've ever seen them with aluminum core fin tubes.

try calling your local chemical and gas plants/refineries

 

i have only seen copper pipe with aluminum fins used in hot water heating baseboards.

 

ill look at the supply shop tomorrow if i swing by either one of them. If they have it, I'll get back with you.

^ nothing, I did get a couple more leads though for a couple more places I have to check.

 

talked to the guy at the warehouse. He didnt know what i was talking about...

what is this being use for again?

 

For heat exchangers on a jrsc. However I have already ordered some off ebay. They are called laminova cores. Supposed to be more efficient than the standard finned tubing so we will see.
