hello.....me and my buddy are starting our reverse flow smoker build on sunday...well he found an old 500 gallon pressure tank that we want to use for our build....but he called me earlier and said the outside of the tank is galvanized but he doesnt know about the inside of the tank.....so until we cut the tank open we wont know if the inside of the tank is galvanized...so the question i have is if the inside of the tank is galvanized can we even use the tank for a cook chamber?....

I would say absolutely negative on using that tank if the inside has been galvanized, you would be asking for trouble. Even on the outside after sandblasting the coating will still be empregnated into the metal. I say run Forrest run!!!!!!! Good luck and keep looking for a tank keep us posted

I gotta back up TQ on this one. I'd hate to lose a member of this site to a chemical oversight like that one. BBQ should be fun - not scarry ...

dang it....this is not good...i was looking forward to start this project......is there anyway possibly to seal the inside if its galvanized...maybe high temp paint or something.....

You're working in uncharted territory there ... sorry but I can't suggest anything on that.

I would not risk it, either.

Bigtex661, Check out your local scrapyard for a propane tank and maybe you can work a trade or at least sell it for scrap. Either way welcome to the world of smoker building. ;)

Start by calling your local propane supplier and work back to their supplier until u find the place that has them stockpiled 3 high for cheap. I have to drive an hour round trip but I can get tanks all day. The older tanks are going out of service like crazy because they have old fittings that are out of code and they can't get valves and gauges for those fittings anymore.

thanks for the tips...ill start checking out the local propane suppliers today......hopefully something will show up.....im ready to start building this thing

Can I just take a moment to express that the comments within this thread are exactly why I decided that this was where I wanted to find my cooker fabricator-builder. A causal lurker can find all kinds of humor and recipes as well as some sharp edged wit anywhere he looks within this forum. He is also going to encounter more than enough tips and hints to build just about anything he can dream up. BUT most of all he is going to find himself immersed in professional attitude when the moment calls for such. Most forums I have encountered are more interested in having the funniest line or the wittiest comeback or even worse just ignoring the topic when someone asks a serious question but within this forum absolutely everyone who commented on this thread took the time to respond that under no circumstances could they endorse using a galvanized tank. Guys I don't build I've made that clear but to the talented folks out there who are jumping off into these projects for the first time the safety minded-professional attitude shown within this forum is priceless.

OKay, stepping off of my soapbox now but I figured it needed to be said and since when do I not speak up when I have an opinion.
Just saying - thanks. Nowadays the average Joe keeps their knowledge like they are afraid that by sharing they will drop down the pecking order

I have heard - and maybe someone can correct me - but I have heard that you can burn off the galvanization by lighting a fire in the tank and heating it for a period of time. Anybody have any input thoughts on that? Or can you correct me?

Gizmo · Post by **Gizmo** » September 27th, 2012, 7:04 pm

I've heard that too alleyrat.
As I recall the gasification point of galvanized coatings is about 392.
And after a period of time at or above that temp (Probably using haz-mat suits) it would burn off and neutralize.
Then again - if it doesn't work then we're talking about you instead of to you ...
Personally I'll stick with just not using it ...

you could end up with Metal Fume Fever or Zinc Shakes!, and thats only from breathing that stuff!........

bigtex661 · Post by **bigtex661** » September 28th, 2012, 9:58 pm

im not having very good luck finding a 250 gallon propane tank......this is gettin kind of frustrating....most of the propane place here in town wont even sell a used tank....the only place that will only had a 500 gallon tank and thats too big for the trailer we have.......

bigtex661 · Post by **bigtex661** » September 28th, 2012, 10:02 pm

a couple of my buddies said to just make a big fire in the galvanized tank that we already have and it would burn all the junk out of it but i dont know if i want to try that....i would rather do it right the first time and build my smoker with a propane tank...

Blazer · Post by **Blazer** » September 28th, 2012, 11:43 pm

Yea bigtex661, I agree, get you a propane tank. By the time you could get that galvanized tank to the temp that it would burn it off it would most likely be warped beyond use. Scrap it and find a tank or a piece of pipe.

bigtex661 · Post by **bigtex661** » September 29th, 2012, 12:08 am

yeah but im having a major problem finding a tank here in town.....most propane companies here in town wont sell a used one and the company that will only has a 500 gallon tank......

Gizmo · Post by **Gizmo** » September 29th, 2012, 4:54 am

Can you cut a 500# down to what you want? ...or 2 of them and sell one?

As an example - we were talking about taking just 2 end bells off one and making a ball-shaped cooker once ...

just thinking out loud here ...

Thats sounds pretty cool to me. Nice diameter for dual racks, limited width for less temp variance. You could even do front and back doors
