Default Source for large (20" to 26") metal pipe? North Texas

I had posted this in sci.engr.joining before finding this group, but
I'll be watching both threads, so if you have an answer feel free to
post it here. Thank you.

original post
Hello, I'm in North Texas (about an hour and fifteen minutes northwest
of Dallas) and I'm having problems sourcing some metal pipe. A friend
of mine and I are looking to for some pipe to build a barbeque smoker
from and the closest place to us, in Gainesville, TX, only has 24" x
3/8" and it's brand new...$52.00 a foot PLUS torch time. I need a
place that I can buy pipe in sizes 20" to 26" by 1/4" somewhere nearby,
and I would like it to be used (I don't want to pay a premium for brand
new pipe, nor do I need the pipe to be certified or pass any particular
pressure test). I wouldn't mind buying used or inspection-failed
propane tanks if they had the proper wall-thickness.

Can anyone make some suggestions of where I might be able to buy this
stuff?

Thank you for your help.

I've got a couple of pieces of 30" pipe out back. I believe one is
3' long and the other is 4' but I'd have to verify that. They're used
and each has about a 8" pipe weld flanged into the side at near one
end. I believe they're either 3/8" or 1/2" wall. I'd take $0.20 a lb
for them.

it's for a smoker. looking at one in the store, it's pretty thin and nowhere
near 1/4".

Hey, Wayne, thanks for your response. I really want to stay in the
20-26" range (I've built one before with 26" and that was getting
pretty big, even for a trailer mounted rig) and I'm hoping to find some
about 8 feet long in one piece. What I'd really like is to find a
source for this stuff so that if I decide to build more, or if someone
comes to me to find out where they can get it, I can forward them on.

I'm going to tell my friend about the pipe you've got, he may be
interested. Again, thanks for your response and I hope I don't seem
rude, but that's just not what I'm looking for (unless I get a
brainstorm suddenly grin).

Hey, Wayne, just hit your site...wow, I'm impressed, you do some
serious stuff out there. I've been to Shamrock (the nursing home there
used my software for nursing orders and such from about November '04
until they closed up several months back) and I know it's not a really
big town; you must be *the* go-to guy for machining stuff out there.

Actually if you'll note the date that overall pic is over a year

The piece you see in the picture is 20" pipe and it is currently in

It's not as common as you'd think at least in my area.

Actually thinking about it I might happen to have a piece of 20"
pipe. I'm not sure if it's long enough or even if I do have 20". I'll
have to got back and look sometime later this evening.

Ok. I just came from around back. I have two pieces of 20" pipe. One
is 7' long and has dished end caps on it (it was used as a air tank a
really long time ago), the other is 7' 9" with 3/8" wall. The second
piece is a really nice piece of pipe. The only concern with it is the
fact that it's got a epoxy paint on most of the outside. Past
experience has shown this stuff to be very difficult to get rid of
though this piece doesn't seem to have as thick a coat as some items
I've worked with in the past.

I've also got a piece of 23" pipe which is in a little rougher
condition. It's about 4' long but has a U cut out of one end with only
3' being whole. Lots of other sizes but most are smaller. The 30" pipe
that I've got is 3/8" wall and has 10" coming out the sides. I was a
little off on the measurement there.

I knew a guy who was allergic to epichlorohydrin due to really sloppy
practices in his younger days. That was why he was a research
scientist in the urethanes dept. instead of the epoxy dept. Every
time we would burn out a die or piece of pipe with epoxy in it in the
fluidized sand bath burn-out furnace, he'd come around rubbing his
eyes, and ask if we were "burning that damned epoxy again". His eyes
would itch like hay fever if we were burning out and he was 1/4 mile
upwind.

Be careful of fumes from burning epoxy.

Hey, Wayne, I had a piece of pipe here that had a coating on it that
appeared to have been tar on the outside (mostly removed by whomever
had the pipe before I got it, presumably the metal yard it had come
from at some point) and beneath that a light teal colored heavy
plastic-type coating. Burning a fire inside the pipe caused the outer
coating of whatever that teal colored stuff was and the tar to soften
to the point that I was able to easily push it off with a shovel as the
fire burned. Does that sound like the epoxy coating you're talking
about? That 7' 9" piece might be alright if that coating is easily
removed by a hobbyist... I don't want to have to waste about 50 wire
cup brushes knocking the stuff off..

Thank you for checking on that stuff.

Wayne, about your stove...it looks like you've coupled a commercial
used oil burner with a piece of 20" pipe and then done a heat
exchanger. I've been struggling for 2 years (just piddlin' now and
then) to make a homemade waste oil burner using a babington burner and
had no real success. Where did you get your commercial unit (assuming
I'm correct that that is what it is), how much did it cost, how well
does it work, what maintenance do you have to do on it, and how hard
was it to plumb the oil and power to it?

:-)

I did have a stove going before that. It was a old coal burning
stove with the used oil burner inserted into the side. It worked
fairly well but I wasn't able to add any extra fuel like wood or trash
due to the limited flue capability. The new stove gets around that
with a large flue capability. :-)

Nope that sounds like a standard wrap on pipeline pipe. It actually
comes off pretty easy with a air chisel or chipping hammer when cold
and aged somewhat. What I'm talking about is a green epoxy paint that
El Paso used to use on there pipe. It's pretty tough to get off with a
wire brush and really needs to be ground off. But like I said it seems
to be thinner on this piece of pipe than others that I've dealt with.
It can be burned off but you do need to be up wind when it happens
(the fumes are really obnoxious as another poster indicated).

The other piece with the end bells doesn't have any paint and isn't
to bad on the outside. I don't have a clue on the inside since it's
closed.

Thank you for checking on that stuff.


No problem.

Wayne, about your stove...it looks like you've coupled a commercial
used oil burner with a piece of 20" pipe and then done a heat
exchanger. I've been struggling for 2 years (just piddlin' now and
then) to make a homemade waste oil burner using a babington burner and
had no real success. Where did you get your commercial unit (assuming
I'm correct that that is what it is), how much did it cost, how well
does it work, what maintenance do you have to do on it, and how hard
was it to plumb the oil and power to it?


That burner cost me nothing. It came out of a old oil fired forced
air furnace. The kind that is suspended from the ceiling and used to
heat a shop. The fire box was corroded to the point of no return when
it was given to me. I did have to buy the tank and pump which feed the
burner or rather trade for it.

The burner works ok as long as you keep the filter changed and don't
let any water get to it. Water is the big killer and will cause me to
have to clean the nozzle at least a dozen time in a week to keep it
running after I let it get to that point. My big problem currently
with the burner is that it doesn't put out enough heat to really heat
the shop completely warm. I have to add wood or other materials to
keep the shop really warm (I must be getting soft since I got by with
lower temperatures when I started).

The burner is rather simple but yet complex at the same time. The
actually nozzle is the exactly the same siphon type as is used in a
major brand kerosene "torpedo" heater (I don't remember the brand
right now). But it needs higher air pressure to work. There's a
preheat tank with electric heating elements in it that preheat the oil
before going to the nozzle. There's also a preheat for the air going
to the nozzle (I'm not positive that this is working on mine). The
high voltage transformer, flame sensing, and safety control are all
standard oil burner components. It has a small draft blower like is
used on a standard oil burner but I currently have it disconnected
since my new stove draws well enough to do without it (and the
bearings are starting to go in the blower). One main feature of the
burner/stove is that there is a float tank which has a float switch to
activate the pump from the main tank. This is placed above the burner
and uses gravity to feed the burner (I made this tank height
adjustable on my new stove so I can control the pressure to the
burner). The pump from the main tank pushes the oil through a fairly
standard oil filter before getting to the float tank. This gets rid of
most of the crud which would stop up the nozzle (as long as I don't
let it get to dirty and start to bypass).

Since I already had the main components it wasn't hard to plumb. I
don't think I would of ever made a burner exactly like this if I was
building it from scratch. There's a lot of complications in the design
which while good from a total safety stand point aren't all really
needed for a supervised burner. If unsupervised burning is needed then
all the safeties are needed. I can tell instantly when it's not
working right as long as I'm in the shop. The sound it makes is
somewhat on the loud side and definitely missed when the flame isn't
doing right.

If I ever get a chance I plan on trying to build a babbington type
burner to replace this burner. But at the current rate don't look for
that till about 2030 or so. :-)

I had posted this in sci.engr.joining before finding this group, but
I'll be watching both threads, so if you have an answer feel free to
post it here. Thank you.

original post
Hello, I'm in North Texas (about an hour and fifteen minutes

northwest
of Dallas) and I'm having problems sourcing some metal pipe. A

friend
of mine and I are looking to for some pipe to build a barbeque smoker
from and the closest place to us, in Gainesville, TX, only has 24" x
3/8" and it's brand new...$52.00 a foot PLUS torch time. I need a
place that I can buy pipe in sizes 20" to 26" by 1/4" somewhere

nearby,
and I would like it to be used (I don't want to pay a premium for

brand
new pipe, nor do I need the pipe to be certified or pass any

particular
pressure test). I wouldn't mind buying used or inspection-failed
propane tanks if they had the proper wall-thickness.

Can anyone make some suggestions of where I might be able to buy this
stuff?

Thank you for your help.

a large air compressor tank that has a rusted out bottom.



With a 1/4" wall? Highly unlikely.

Harold


it's for a smoker. looking at one in the store, it's pretty thin and

nowhere
near 1/4".


Understood, but the man asked about a 1/4" wall. I simply didn't want him
to think that's how thick air tanks are. I agree, an air tank, or even an
old large diameter water tank might serve the purpose, assuming he doesn't
really need the 1/4" wall he's talking about. I didn't want to
re-engineer his project, for he may have good reason for the thickness he
requested.

Harold, thank you for your points, and they are a concern. I want 1/4
inch because I feel it will hold up to years of service, particularly
where the fire is actually built inside; the intense heat and,
presumably moisture from the wood or perhaps moisture from humidity
and/or rain seeping into the ashes, seem to cause thin metals to rust
rapidly (I've seen fireboxes that were 1/8th and 3/16th thick that had
*supposedly* only lasted a few years (maybe 3-5). While that's all
loose information, and I've not done any testing to see what kind of
longevity I can get (and any testing would seem to be subjective to the
particular design and environment), the amount of time and effort that
goes into building one of these things (I spent about 10 months of free
time on the first trailer-mounted one I built, including the trailer)
it would be a shame not to build it to a spec that I feel comfortable
with. 1/4" sounds good to me, 3/8" inch would seem excessive but I'll
do that if that's all I wind up using.

Anyway, I appreciate your position of accepting the requirements that
I've set up for this.

I think you have a valid position. If the cooker requires much effort,
you could find yourself rebuilding it quickly thanks to corrosion. I had a
stainless burner assembly go south on me in a gas barbeque, something I
swore wouldn't be a problem. The products of combustion coupled with
moisture seem to raise hell with metals.

Good luck with the project!

Harold
