3/8" wall seamless tube

[civilcannon]

Hay you metal guys:
I have never heard back from Bill AT CCC reguarding the 1/5 ths scale barrel that I was considering so I may go to plan "B" this would involve a cast bronze barrel bored and sleaved with 3/8" wall seamless tubing to meet safety specs. I recall 85,000 psi  minimun? does that sound right? Any way do you know of a source or is their availible a 1.75 O.D. and 1" I.D seamless tube that would meet the 3/8" wall requirement. What grade of steel would be recommended and who is a good source for a length of 2 feet of this material? The breach would be threaded & pined or welded and pined ? what is best?

Thanks: Civil Cannon

you may wish to go with stainless steel most high pressure applications use stainless now it seems , plumbing supplies won't have it as a rule , try speicalty piping supplies , another sorce might be to bore a piece of bar stock , or a ss bolt !
the old big black powder guns used for waterfowl would slip pipe inside one another to get the desired thickness not sure thats a good idea or not !
Frischkorn Inc may help they are a speicalty piping co.

Ah, Shootall,  pipe is welded seam and definitely not for cannons.

Civil Cannon is looking for seamless tubing to comply with the safety  standards for cannon barrel liners as established by  N-SSA and AAA.
