Good old boy, when I read your post, the wisest part of all was when you asked whom else could weld it, which tells me that you aren't experienced enough to try. That's a good thing. My brother-in-law deals with LP as well as welding gasses for a living. I'll ask him tomorrow how they deal with tanks. In the mean time, just let it sit in the corner and don't fuss with it. When I was a kid, a neighbor went into the barn by himself to work on his LP Case, and no one's sure exactly what it was he was doing, but it leveled the barn. His daughter found one of his fingers in the yard a couple of weeks later, well after his funeral. I'd guess that tanks can be, and do get repaired, by people that do it for a living. It's too late to call him tonight, and I'm sure that he and my sister are in bed for the night - and they'd better be seperate beds, or I'll deck him, right after I get you an answer.

Paul Janke posted a sensible reply. I have welded fittings into two propane tanks, 100 pound size, for use with compressed air, no problem. The propane has an odorant added, methyl mercaptan. When the odor is gone, so is the propane. Put about 100 psi air into the tank and let it out. Probably will have to do that twice. When the odor is gone, you have just an empty steel tank, the propane leaves no residue. But welding for reuse with propane is a different matter. I would get the best weldor ( a weldor is a person) possible and then test with air at 175 PSI. Propane is stored at higher pressure, this test is for leaks in the weld area. If no leak, cleanup and paint the tank, THEN have it tested for propane. No mention of any repair- they will automatically refuse to test for liability reasons. Sometimes replacements are not available and we must repair or do without. This plan is the one I would use if the existing tank must be repaired.

If you are pressure testing do it the proper way - hydraulically first and test at the correct level - much in excess of working pressure. A pneumatic failure would be explosive even without any propane present. If it fails in service..... ..

Take the fitting's out and steam it for one or two hours,fill it with water and you will be ok
to weld the bracket on.

Short of a PROFESSIONAL AND CERTIFIED repair, it's kinda like using a match to see how much gas is in the tank isn't it ? Make a new one or Strap it down (and not with Bungie cords or rope).

Are you crazy? You don't use bungee cords or rope to fix anything, you use duct tape or baling twine...duuuhhhh! If you can't duct it *@$# it!

One thought which occurs is if it were successfully welded, it is still subject to high pressure for the rest of its life with a leak being dangerous, as opposed to an air tank which would just cause loss of air (assuming not a complete sudden failure).

No problem with welding a propane tank as long as you don't mind ending up where I did. It was a fast trip, I went straight up here without being buried in the ground first. Good thing I behaved myself all those years on the ground or I would've had a long trip back to see Lucifer. Anyways, gotta run, the local angels are coming over for a party and they really know how to make a guy happy. It's a pretty good place to be. See ya.

If your needing a lp tank for a Farmall H I have one here that I have listed on another site for sale right now but it does not have any bids on it yet. Its a 23 gallon(I think).

LP Tanks are about $1.00 a gallon at the salvage yards. So if you have a 50 gal. tank you are looking at $50.00. If you weld it, you are liable for it. Anything, and I mean ANYTHING, should happen you are going to be resposible for it. Buy a tank, use air pressure to check it for leaks. If this is an "after market" add on tank you may have to settle for a different size.

Good Old Boy, NO!NO!NO!NO!NO!NO!NO!, ARE WE CLEAR ON THAT! Now, What kind of tractor do you have? Let this croud locate a tank for you. There are tons of old LP tank out there in wrecking yard just waiting to be put to use.
Give us specs on this tractor and see what develops, Also where are you located? If your in Texas I have 3 yards in mind off the top of my head. Later,
John A.

Replace the bracket with a strap that goes around the tank, bolted to tighten it up. Much cheaper than funerals, and more impressive than earning a Darwin award, which is pretty much guaranteed!
