Need to turn the ID of 16" pipe

[bignissan]

I've got a 90" long section of seamless pipe that I need to have turned to get the ID concentric all the way through to remove the standard ovality. It's 316 ss, 16" od, .375" wall thickness, 90" long. Can anyone here do that?

PM me.
Thanks!

Thats gonna need one big lathe. Machine shops in houston are so busy these days, I doubt you are going to find somebody who wants to do that. If they did, it'll be for lots of $$$ and a 10 week lead time!

Just out of curiousity, what kind of application is this for?

[bignissan]

Yeah, I've got some places that can do it, they are specialty shops for hyd. cylinders and such...heck the material alone for this piece 2 years ago was $9000.00....I'm getting quotes of ~$14,000 for the matl. alone!!! Doesn't really matter....just need to get it done.

A low pressure hyd. cylinder basically....think of a floating piston, no rod, just to seperate two fluids. The piston floats to allow fluid level changes of each fluid...make sense?
