Possible to Un-Crimp Pipe?

Silly question, is there a way to un-crimp pipe ends? The reason I ask is I just moved my stove and installed a new ceiling support box. I know crimped ends should go away from the stove, unfortunately every support box I've seen has a crimped end on it. I have my stove hooked up with the crimped ends away from the stove. The problem is my stove outlet and support box both have male connectors. I cut the crimped end off a piece of black pipe making a female to female connector. It works, but I was just wondering if it was possible to un-crimp the ceiling support outlet so I could slide the flue pipe inside of it?

Find something just smaller than the pipe. Slide the crimped end
over it and pound the crimps out with a hammer. Might take a while,
but the material is there it just has to be flattened out again.

Crimp down...
Keeps the water in your pipe...
No drips on the outside...
Just sayin...
And they made it with the crimps down...

DITTO--that crimp up or down has never been carved in stone coal stove wise---mine is crimp down--always has been, always will be---converted wood burner & it don't make a bit of difference

OK, next question. I have a male connector on my stove, is this common on most stoves? I assume most people encounter my unique situation trying to connect 2 male ends...my stove and support box!

If you stop by a local well stocked stove shop......or hardware store you will find all sorts of adapters that may solve your dilemma. Un-crimping is not a fun project, and if you can solve the issue with a $10.00 adapter, so much for the good.................

A good stove shop will have the pipe you need...
Stove connector...
Pre-made...
Or if you are lucky to have someone that rolls their own...

Anything can be made...

I have a Coal Chubby Stove, it's made that way. I figured out a fix for my problem, I was just curious if others ran into this. I'd like to hear if other stoves have a male connector on them.

Here is the manual for my stove. On the bottom of page 6 you will see a note about pipe direction.

It's more important that the crimps be down for wood than they be up for coal. In a perfect world it would not matter. But folks burn wood that is not well seasoned and water and creosote drain out and run out of the pipe joints if crimps are placed up. Coal of course doesn't have that problem but the idea was that flue gases would not escape if the crimps were up.

It's probably easier to just unsnap the pipe and trim the crimp off with a pair of shears.

We just switched our stoves or are in the process of switching to female flue outlets. I really never liked the stove pipe over the flue outlet. Back to topic I agree buy an adapter it will save lots of frustration and will look nicer.

It does when you have a decent puff-back...unless you sealed the seams.
