Removing a rusted boiler plug

Interesting reading.
Personally if I can wait I will soak the threads a few times over a days period with a super product that I swear by. PB Penetrant. Got mine it at Lowes. I was very skeptical but it does work great but you do have to give it some time to penetrate.
Then a long bar on the rigid.
Then the heat with some smart taps on the fitting.
Then the Yankee inginuity offered to us.
I do agree that we should all realize where our limitation stops us and we should swallow our pride and ask for help. The further down the order of steps requires some more care and some people are simply not detail oriented enough to be trying some of these things.

Thanks for the ideas!

PB Blaster? Yeah, good stuff. I keep it in stock all the time. Great on exhaust manifold studs.

Yes I Know The Differents in Mapp & Acetylene Gas . Maybe they where called welding tips in the old days But Today in 2009 there called torch tips http://www.nationaltorch.com/tips.html

WhereTF did you come up with torch tips? That's not a real torch. That's an imatation.

Se below for a real torch!!! That's what I used! You were still shooting bb's in the strip mine when I was cutting and welding with mapp & lox.

Yea Your A Funny Guy Cap What you got 3 years on me Please. In turn I have been around coal mines & burned coal fired units before you ever knew what coal & coal fired units were Why Don't you come up to the shop and show how to work on some these coal units and show me how to use a torch . Because I guarantee you You will be thrown out on your A$$
along with your B.S. in less then 30 seconds . I am done with you do yourself a favor loose My Number .

Do you heat the plug or the surrounding female flange? I have tried in the past heating surrounding areas and then quickly put ice on the plug to try and shrink it before it cools off the surrounding area. It would be great to have dry ice to try this with.
This is my rig that I've had for many years. The oxygen bottle has its first test date 10/58. It's older than I am! I need to get it filled every couple years if that. I swap acetylene bottles from time to time at the local welding place. I have a cutting torch that comes in handy when I need it. I took a welding course in Binghamton a long long time ago; the teacher Mike Koltz, seemed to have permanent pinhole pupils in his eyes! ( And pinhead pupils in the class...) Never forgot that guy. He could cut steel like a human straightedge.

Lighten up! Please! You know coal boilers. I know how to weld, cut & braze.. Been doing it since I was 17 in a shop with industrial equipment & large asme coded vessels. Your not the only one working around steel, dirt & rust. I do it too.

OBSERVATION: I removed 6 plugs from my boiler in less time than it takes to read the previous 22 posts. I didn't have to drag out my burning equipment, didn't get involved in one-upmanship, or have a contentious argument with anybody. Can life be any simpler?

For those that have oxy-acetalyne (welding or cutting tips will work, size of tip will only cause more or less heating time), heat the bung that is welded into the boiler to red hot while trying not to heat the bushing or plug. As soon as it is dull red all the way around it will turn right out.

Stokerman has a nice solution for those without torches or for work where dragging the torches in is not desirable.

Play nice fellas!
