Assembling black pipe for burners

[Protactical]

I am making these burners, some parts from black pipe, and others from red brass nipples.

There are:

Black pipe to black pipe joints, both threaded and sleaved;

Red brass to red brass joints;

Red brass to supply joints;

Joints between various valves etc... in the propane supply chain.


How does one make all these connections? I am assuming the black pipe just goes together with that cement they sell. I have read people saying don't assemble the brass etc.. with teflon, even in areas where it shouldn't get heated. For instance the zoeler burners call for using a welding contact tip, in a threded hole for a burner. Those joints won't be tapered, and they may get hot.

Any ideas?

I use and make blower forge with black pipe burner and just tighten them up snug. So what if they leak a little air???? Brass to brass you shouldn't need teflon tap.

Cement? I use plumbers paste on all my fittings...designed my burner so it does not even get warm though. Are you asking if they screw together? Some of your fittings are sleaved? Got any pics?

I don't have pictures yet, I am still putting them together I have started with a Reil style mini burner, And have tons of parts that are making their way through the line. I hope I will have a regulator/gas etc... set-up on Monday. At that point I will want to get at least one going.

I guess you are right, George, that the jet is probably firing down the middle, and if anything happened at all, it would be air pulling in through those joints. The only non-threaded section is the burner flare area, which probably comes under the same category.

I want to order the Zoeller flares, it's just taking quite a while. The sleeved ones would be flares at the end that just fit over the black pipe. Not sure calling that sleaved is correct on my part.

The one fitting that I still wonder about is the burner tip, it isn't a tapered thread, it is brass, but it won't assemble as brass normaly does with tapered fittings (unless I buy a tapered tap), and it does have gas pressure behind it. I guess I will have to ensure that it never gets hot, I am planing on the removeable burners. Here is the side burner drawing:

The connection I am wondering about is the point where the Miller contact tip connects to the Sched 80.

The Reil mini I am making doesn't have that part, so that's fine.

Thanks all
