Have you considered driving the boat using a steam turbine?  This was normal practice years ago when steamships  were in vogue and had HP and LP turbines utilising high pressure superheasted steam!  I seem to recall the Reeves used to sel akit for a rotary steam engine.

Can you thread the ends and use a coupling welded on the outside? I dont know if the wall thickness would allow threading. If not, then just a sleeve welded on. Silfos flows at 800C and braze at 640C so they will do you no good. Welding is your only choice for this application. Use an external sleeve and find an aircraft welder and he will do you a fine job. You will have to ream the weld from the interior penetration. I reread your post and see 60' and not ". You will have to live with the penetration, or do many, many short sections and clean up as you join them. I assume that is not feasable.

Another thought is if you can thread the pipe, a coupling could be welded just to seal the end and not require penetration.
