Answer
Aluminum cannot handle high pressure all that well as you have seen. It will handle 2900 PSI if the wall thickness is thick enough. My guess is your first tube burst at the bend. Bending the metal will weaken it. Aluminum is not very ductile (bendable) so it tends to fracture easily when it is bent. You will have this problem even with a thicker wall tube.
Stainless steel would be far stronger and with the right wall thickness could easily handle the pressure and bending. The BIG drawbacks are the it is very hard and not easy to bend and also is very heave compared to aluminum. A 16 ft piece of 1/8" wall tubing would weigh more than 40 lbs. Not something you want to lug around all day.
The only thing I know that is light enough and strong enough is composite materials. They cannot be bent after they are laminated up so the bend would have to be part of the manufacturing process. Very, very expensive.
Good luck

What can I use to clean the ground of my drive way?
Kim
I just bought a home and I am doing some cleaning. the driveway ground is very black and dirty, probably from the gutter being recently cleaned after a year.
what can I use to get the ground white again?
Answer
If your driveway is "ground" i.e. "dirt" you can't make it white.
If, however, it is concrete, your best solution is to rent a pressure washer and use a mild solution of TSP (tri-sodium phosphate, available cheap at any paint department -- but do read the mixing directions; it is powerful stuff).
A good gas-powered pressure washer with TSP in the detergent tank will remove dirt, oil, grease, and anything else dirty on your driveway -- but do read the directions girl and don't point the thing at anybody.
