Suction lines by piotres

It's Vinegar , it turns light green after few uses to clean cooper .

I check if for leaks in pure water in 25 bara pressure .

so does the vinegar remove the oxidation or does it just polish the copper?

[piotres]

remove oxidations

I use a wire brush then sand paper, I'll give the vinegar a shot Pio, hope you don't mind.

I thought wire brush and sandpaper was a no-no.

[n00b 0f l337]

Why not?

[sjg0]

Why not?

Idk. If you sand down too much you could open a pinhole in your braze?

Copper dust gets inside system?

[one_servant]

Naturally, you "could" sand that deep...but the chances that you will breach are very slim. For example, lapping is just fine since the bottom of your evap should be a very thick chuck of copper anyway for good heat transfer.

[n00b 0f l337]

Exactly, that'd be a hell of a lot of work And get you nothing, I like the vinegar idea though, as long as it doesn't cause oxidation afterwards. And it does seem to create a really nice clean, or do you end up really sanding and lapping away after pio

[sjg0]

YEs vinegar sounds like a very good idea, but does the copper need to be soaked in vinegar for like hours? or can I just pour it over tubes and it immediately breaks up oxidation?

[Bitemarks666]

i would imagine that a overnight soak would be required as vinegar although acidic is not that strong

[sjg0]

So then piotres, how do you soak your last joint?

Do you have a wierd shaped bowl that you tip the unit into when you want to clean up the last braze?

Or do you just sandpaper it like nol?

[teyber]

he said in one of his threads he sands his joints and cleans them with a wax that he uses to clean his car.

- Vinegar is acid
- Acid gets rid of oxidation
- Acid on inside ruins compressor

You must let it sit for like a day.

[n00b 0f l337]

We;re talking just evaps here friend, other joints you can juse use a wirewheel or such.

Hello

I've not been writing anything here since quite long time but all of that is becasue I'm very busy since some last weeks . Next year of studies (3rd ) start from October so I have less time now . But I've make some suction lines and braze some evaps since that time , so I decide to show them You :



Some cooper cores of evaps .



Some brazed evaps with captubes.





All evaps are pressure tested in 20-25 bara .











I have new enclosures and backplates for Nehalems .










Regards
Thanks for looking
Peter

Very nice work there. Wish I could get my hands on one of the cpu evaps.

[sjg0]

Good job.

[teyber]

dunieks new mountings look hot. The painting on that backplate is ZOMG. love it dude!

[piotres]

Thanks Those BPs are not painted .

[teyber]

They are not? optical illusion? they look like a very thick, perfect white paint job...

[Polizei]

Powder coated maybe?

Nice work Piotres, top notch.

[kamongear]

Maybe a plastic film on the metal or a plastic?

Great Work

backplates is made from DIBOND

and yes this white is plastic film on aluminium layer

dibond is 3rd layer material, piotres has 3mm backplates (0,6mm alu + 1,8mm Poliethylene + 0,6mm alu + plastic film on both sides)
