Both steel tubes have one seam weld that was ex-rayed. The tubes are 39" OD and 1.1875" thick steel. Type of steel is unknown at this time, but since they were part of a natural gas pipeline it should be good material. I'm getting a digital metal tester that will tell me what type of steel it is.
The weight is 4100 lb. for the 8.5" section, which comes to 512 lb's per lin. foot. The other tube could be about 11.5' when the rest is removed.
This would be used for a pretty deep diving sub, and would require a hell of allot of hard and soft ballast systems including syntactic foam. I can get both of these for 10 cents a pound, so I can't really loose. To have steel of this size and quality rolled, professionally welled, and ex-rayed, would cost a hell of allot more then $400 or $600 I would pay for these. I'm still debating this in my head so I could use some good imput and a big flatbed truck.

Brent

3/16" doesn't allow much room for corrosion.
Just finished the detail work for the hull shell, end caps, and rings,
....the works at this point weighs 1880 lbs, 42" diameter, 3/8" thickness,
same length as before.
Yes, using Flamingo bundled with Rhino Marine.
