Alloy water pipe
rdodger - 29/3/17 at 01:51 PM

Afternoon all

I need to make up a 32mm alloy water pipe with a 10mm barb. As I don't have a tig and can barely weld steel anyway I wondered about alloy brazing. I have seen the guy at Stoneleigh happily gluing alloy together with his torch and magic rods but wondered if anyone had tried it and what the results were?

Can't see why brazing wouldn't work... I braised my sump together...admittedly steel..

Have you got the parts already as if not it maybe worth just buying one as there not expensive these days .

Hi

Do you mean buy an alloy adapter that takes a barb? If so I have one of those already and want to get rid of it to reduce the number of hose joints as the piece required is about 300mm long. Mostly though to make it look nicer :-)

You can buy alloy pipes in lots of different lengths

I'm not sure I understand what you are saying? I need an 8mm pipe to come out of the 200-300mm length of 32mm. So I either use a boss with a barb and join it in with hose or I weld/braze the 8mm in to the length of 32mm pipe.

Any way. Has anyone brazed ally?

Sorry totally misread your post you can get 200mm alloy pipes with a tee piece but I think that's the maximum length.

Just offer some beer tokens to someone with a Tig to do it properly. I've heard of good and bad results from Ali brazing.

I have a Tig but not in Manchester

I went to a local small business exhaust repair place, asked for them to stick a couple of bits of weld on either end as I needed a Barb.

He did it right there and then, took 30seconds and I gave him a fiver

Thanks for the replies

I have enough material to do it twice so I have ordered some brazing rods & flux. If it doesn't work I will take some more bits to a local fabricators to have it welded.

Well I gave it a go and it came out pretty well.

I watched a couple of youtube clips to see if there was anything special to look out for. To be honest with the special flux and getting the 2 parts nice and clean, it's pretty straight forward.
