80mm Round Galvanised tube

[Big Shed]

Looking for some 80mm round galvanised tube with a wall thickness of 2.5-3mm.

A piece 85mm will get me started, but will take more if available.

Want to make a security lock for the king pin on my 5th wheeler.

Thanks RC, it appears hat the one I looked at (80mm diam) is an Imperial nominal 3". The 65mm NB would be too small an ID and the next size up 80 NB would be too large an ID.

The one I looked at had an ID of about 75mm.

Hoping that someone would have a bit of Imperial pipe kicking around.

Hi Fred,
I'm fairly sure I have some 3" gal pipe bits you can have.
However, I wont be home to check until Monday night. If not more urgent, give me a call on Tuesday.

Thanks Joe, will give you a call on Tuesday.

If you can't find a piece the correct size, I've used a size that was close, cut a piece out and then welded it after clamping to size. Have also had it where I fitted a piece in to make the size.
