black pipe for natural gas

[Sberry]

Steel couplings or steel reducing bushings weld well also and are readily available, get them at some hwd stores.

I have welded a lot of the cast fittings over the years but wouldnt use one where it was critical or under high pressure, done it for domestic water pressures, even used one a while back for a breakaway bracket, it fails before damaging the equipment.

[Goulet!]

Would that thread o let also be known as a pipe saddle, or would that work the same way? It looks like a weldable steel fitting that's threaded on the inside, unthreaded on the outside and beveled at the end that goes into the other pipe.

That would be it. I think Sberry is on the right track with using a steel shipping coupling that would have flat bottom verses a bevel. I am assuming your only running 7" w.c. for pressure correct.

You will get two different answers for your . Reason is not all pipe fittings are created equal

Lots of the mallable iron fittings you find at your local hardware store can be welded but its a crapshoot on weld quality. I have seen some crack and some don't . Reason is the carbon content of the fittings are all over the place

If you however go to a high quality fitting ( go to an industrial pipe supply and use the ANSI 300lb and up fittings. They are commonly available to 1500 lb or higher. The steel quality for these are far higher and therefore easier to weld on

BTW you can also buy these threaded fittings in a "weld on" fitting. They are pretty cheap

If you are just making a welding table have at it

Have you ever looked into building a still, or are you strictly a beer brewer?

I usually use 7018 on them, they dont get as brittle as most casts but the 18 helps with cracking.

Yes, thread-o-let fittings are weldable...there are weld-o-let fittings for flanges, in a number of different sizes...here's one I did.

[Sberry]

Trg made the point, they are unknown especially in regard to carbon, they do get welded to all the time but where they need to be reliable they need to be steel. I adapt the air brakes on a truck from metric to American, steel adapters to steel adapters. Stuff like gas manifolds have no pressure but you might not want to have some piece just crack and randomly drop off either, with all steel its not a problem, here its done with wire feed, converted a burner the other day to LP from Nat, couldn't source the parts, finally made it in a few minutes, should have done it that way to start with and would have been done. I spent twice the time looking for a part as it took to make one.

Brewing beer for your own consumption is legal; distilling spirits for any purpose entitles you to the hospitality at a Club Fed facility.

No, it's strictly 'for my car'......

.....that's still 'legal' here in the US.

How about wine making???

Wine isn't 'distilled', it's fermented (like a beer). In a simple definition, 'distilling' is a post-fermentation process for removing the alcohol from the mixture.

Yep, I'm a reflux still guy myself......

...for 'the car' ya know.....

Did you braze it? Where did you get the big copper fittings?

[Rocky D]

That was a solder job, and who ever did it was very nervous...like maybe the revenuers were close by, when he was doing it. If it's lead solder, it's poisonous, so the mountain dew that come out will have more lead in it than a Matel toy!
