Never noticed before, but some pipe from my 3 year old stock (BES
sourced IIRC) shows what looks like a seam:

Curious... I *thought* copper pipe was drawn. Is that a welding seam or
just a mark from drawing.

That just looks like a scratch to me. Is it visible on the inside?


Not that I can see - there are various "pencil lines" running
longtitudinally - must be just die marks I guess.

The long mark turns out to be 2' long - so yes, must be a manufacturing
scratch. It should miss the compression joint so I'll use that as is...
