NB ALL TUBES ARE SUBJECTED TO CHEMICAL COATNG IONADIZATION PROCESS TO PREVENT AND SUSTAIN SCRATCHES AND CORROSIONS.

Do you need that high qulaity for anything other than centrigfuges?

Need some engineer types and weapons types to think about this....

Those are not rocket tubes. Steel is used in rockets. Aluminum melts easily and burns, too. Forget the pound for pound stuff when it is pooling around your feet.

"Do you need that high qulaity for anything other than centrigfuges?"
I am no expert. But surely one would not want rocket tubes to weaken due to corrosion any more then one would want corrosion to occure in parts for gas centrifuges.
Plus in the case of using them for rockets. One would not want an outer surface pitted and coated with any corrosion from effecting the inner surface of the rocket launching tubes.
I could see in either case the need for tubes with a very clean surface. I believe, but am not 100% certain, UF (uranium hexa fluoride) may be corrosive. If so, it would be quite important to protecting the underlining aluminum which may be quite subject to corrosion from this gas. Quite frankly. I am not sure just what part of a gas centrifuge the tubes would be used in. I think the where not intended to acutally pass the gas, but in part of the balancing system. If so, then they may not be required to be ionadized.
Just a very un-educated thought. For "interpiping", I would assume they would use some grade of stainless steel.
Perhaps someone will step in with a better explaination.
