I spent many years doing that in the Navy as A boiler tech with the NEC for boiler repair. the worst is in the mud drum, That dam gun could kick your butt. Memoirs from the past.
@@jeffreyrhammond Ah thanks, I'm looking to do something with 3/4" and 1/2" diamerer copper tube, not had alot of luck using regular drift, thought this might be the go.
Looks like a pretty cheesy installation compared to the way the old tubes are neatly and consistently installed with a square shoulder. It looks to me like flaring the tubes like that would tend to want to spread the holes in the sheet and distort it.If those are the only new tubes being installed I assume that's the portion of the boiler that gets hottest and most corrosive gases. How does the tension and expansion rates of those new tubes compare to the old tubes?
that sheet is more than an inch thick. deformation is minimal. tube sheet hole deformation is mostly from cleaning and prepping after old tubes are removed and is accounted for when selecting roll gear and mandrel combinations

In a 4inch scale traction engine how do you do the firebox end being so small area to work in
This video should be titled "world's slowest drum rat"

Is it an off the shelf tool somewhere and are there multiple sizes?
Cheers!

@Martin Turner and most likely seal welded for a heat sink
That's either a steam or mud drum tubes are just rolled no seal weld needed.

That’s a steam drum the mud drum would be overhead and it’s all of a couple of inches thick
Nice and informative
Can you roll tubes slower than that?
just ask, anything can be done
The air tool only had one speed. But if you stopped for a bit it could take longer
@@jeffreyrhammond What is this tool called?
How can you get one of these out if it’s snapped off in the tube sheet?
I’m a little late here but you cut it out with a air arch and weld a plug into the drum,not something you really want to do with a new tube
Dear Sir is this a Oil Cooler expansion or water cooler?May I know this tool brand? Made in? How can I oder?
انا محتاج الاله دي في مصر
Not sure what the brand was. This was in the steam drum of a boiler. We rented the roller

Hello friend. Whats is country ???
I worked 10 years doing this type of service here in Brazil
This was in Calgary, Alberta, Canada
Very nice! I like it!
is this prior to tube removal or is this the tube insertion and sealing process !! I'm confused a bit because, part of the tube has come out !!
Warnaka Dias Pannilaratne this is sealing of the newly installed tubes
Thanks alot !!
Why do you do this ?
To expand the edge of the pipe, this prevents gas leaks
jadi ngak pakai welding ya mas

Hay gue darle fragua a los tubos ante mandrilarlos
Oh some of the comments on this are great. So many people don't have a clue 😂😂😂😂
good

I have 9 years' experience with boring tubular bundles
