We use a lot of carbon steel square tubing in our products.
Earlier this week, there was a noticible "rattling" coming from inside the tube while a product was being rotated in a positioner.
After shaking and listening to locate the source, the weld supervisor decided that one one the welders probably left his pliers in the tube before it was welded shut and had the offending tube cut open to remove the rattler, which turned out to be a large glob of previuosly melted steel that looks like a big slag ball. (see pics)
We then checked the rest of the tubes and found several more that were slightly stuck to the inside.
Has anyone ever had this problem before and can anyone tell me what caused it?
We consulted with the supplier first, and all they have said so far is "Oops, sorry."
Thanks,
Tim
I've had backing bars that has fallen down inside the tubing before, but nothing like what you have pictured.
Hey Tim, sorry for the not so serious reply. But the foreign countries have found a way to dispose of their hazardous waste. LOL i hope-Ted
Maybe I should collect and try to sell them as meteorites...
Anybody want to buy one?
Tim
Dangit...now look what you've done...I found some, not the same extreme as you did though...this is Canadian made tubing
Material receiving or pre-fitup inspection may have eliminated cutting off the end cap.
The slag is from the seam weld at the mill. Supplier has nothing to do with it, they just move it. They are a broker. Hey, I'll buy one! lol

You're absolutely correct PipeTommy!
I'm referring to the last pic. that is...
The other ones look like they're Iron Man's Sh!t for crying out loud!!!
Has he come to visit your shop more than once Tim???
Respectfully,

Looks like You need to pull a chimney cleaner through every tube...
That obviously did not come from the flashing as it was seamed up.
Those pictures look to be refuse from a continuous casting process. I doubt very seriously it was part of the tube itself. Suggest a bit of research into the firm your source as it's more likely an employee chunking them into the finished product. That is only possible if the mill is also producing the tube.
