Entertainment purposes: Don't use welded steel pipe for corrosive service, an example: 2

I thought this was entertaining, it's 1.5" sch 80 welded pipe as an overboard that services gray water, black water, and salt water.

That's literally the seam hanging off the bottom of the pipe.

At least they spent a little extra on the flange bolts

I used to have a photo of a SS pipe line that had welded pipe from two suppliers.
The welds had rotted out of one, and the other was intact.

This is probably continuously welded pipe. The only thing continuous about it is the name.
