Bending 3.5" O.D. pipe pile

Is it possible to make a 90 degree bend with 3.5" diameter pipe pile?

I need 2 feet longe pipe pile with 90 degree bends at the end which will be welded to a plate (will look like bike rack or so) The pipe pile is pipe #3 double extra strong per AISC table 1-14 (O.D. 3.5", I.D. 2.3").

Thanks

Depends on the radius of the bend. Call a local fabricator. My guess would be the radius will be pretty large
 
You can always weld a 3-inch (nom) pipe 90-degree bend (elbow) to each end. Do you really need Double-Extra strong? A long radius 3-inch 90 has a radius of 4.5-inches and a standard bend is 3-inches. The short radius in XX-strong will be VERY hard to find, might an X-strong or Sched. 80 (both are 3.5” x 2.9”) work?

I'm not familiar with pipe "pile". Assuming it is ductile enough to be bent, then yes, there's folks that can bend it in whatever shape you need. (And, if it's not especially ductile, regular A53 pipe could be bent to any reasonable radius, or it could be hot-formed). It helps if you're in an industrial area, or else willing to haul it halfway across the country otherwise. Pipe that small can likely be rolled on a large angle roll.

One source: " allow the formation of long sweep elbows from round, square and rectangular tubing up to 28" outside diameter"
 
To bend the pile in the field would require a pipe bending device, which would be difficult to find for portable applications (this is not a "tubing" bender, but a pipe bender). Further, as noted, the bend radius will be large.

The suggestion to use a standard weld elbow is a good one. You could also miter the pipe at a 45 deg angle and weld it back. This would provide a sharp 90 deg angle with no bend radius.
 
Thanks everybody for the feedback.

Can I make L-joint instead by cuting at the pipe edge 45 degrees (2 piece) then weld same making he right angle? Thanks again..
