Stainless Steel Tubing

[Kompulsa]

Hello.

I was wondering how many of you have considered stainless steel tubing as an alternative to copper? It is not that I am trying to use it, because I probably don't have the tools for it, but I am curious and want to talk about it.

I see it for a lower price than copper tubing here: http://www.ebay.com/itm/25-FT-STAINLESS-STEEL-TUBING-5-16-X-020-TP304-304L-NEW-/110714357886?pt=LH_DefaultDomain_0&hash=item19c717087e#ht_3013wt_907

I guess stainless steel tubing does not leak nearly as quickly as copper?

I like the sound of it...

Stainless Steel is not generally considered because it is not a standard form of installation as its harder to bend and more difficult to connect to standard Brass fittings due to electrolysis

You can buy annealed stainless tube which is a bit harder than copper.
You can also flare it.

USE 45% silver solder to braze it, same as brass & steel.

Do you know if that ebay tubing I showed you is annealed? Can my 3,600 F brazing torch and MAPP gas work for stainless steel tubing?

Ok, I changed my mind and am seriously considering the stainless steel on Ebay now. I am trying to get the shipping weight of it from the seller. Why don't they just post that on the page.

A PDF recommended JMM Argo-braze 56 for stainless steel brazing where crevice corrosion is concerned. I need to find out what type the store sells. I need to know if the brazing alloy I usually buy from them is at least 45% silver because I am fine with using that.

why you do not use steel pipe instead of copper , it is cheaper than stainless steel and also in low size of pipe you can band it , in some of our project we used it. (inside of pipes it should be cleaned ) it is very good .

Kompulsa,
The annealed tube is usualy 6 metre lenths (not coiled up like copper).

The 45% also requires flux.

They may also ask for tube wall thickness,ppressure rating is important but probably not a problem
if its hydraulic tube.

the steel pipe grade should be 40 as same as we use in NH3 systems.and it is good for large system with long length pipe works.
