I like how swellguy thinks!! First reading your thread I thought just touch-up the pipes and move on, but now it seems that just won't suffice. I'd call him and be polite, and not hang up until you've got what you want, or have gotten nasty. Carpy should understand that even shippers make occasional mistakes and your's might be one of them. Or, maybe the pipes were all wrapped up in bubble wrap and the fabricators or ceramic coaters made a mistake without Carpy knowing. Either way, I believe that Carpy didn't knowingly ship scratched pipes, and that the burden of your satisfaction is on his shoulders. This might upset him, but it is his responsibility. You weren't delivered the goods you paid for! I'd tell Carpy to make it right by you and the rest of this online community - by arranging monetary compensation for a mistake obviously not yours, or completely refunding your money including the return shipping costs.
Heck, if you need a west coast adversary, I'm about 30 minutes from his shop.
Good Luck
