Pipe welding T-joint or "L" joint

I realized that making 90 degree bend with 2.5" diameter xx-strong pipe (per AISC table 1-14) is difficult, in addition the short radius elbow may be difficult to find.

I needed three (3) feet long pipe with 90 degree bends at the ends (like a bike rack or so). I thought of making the right angle in form of “L” joint by cutting the pipes at the edge (45 degrees) then weld together to make the 90 degrees.

Is this approach is doable for the pipe size? Is it better to make T-joint instead? I really need to go with L shaped edge but don't mind going with T-joint if it's better for any reason. Any advice?

Thanks

What pressure and temperature is your fluid?

Can you sketch your problem please? - Sorry, but I can't visualize it from your description.
 
What if you cut your pipe in 22 1/2 degree sections and had a three piece 90? You would have less pressure drop, and still maintain your angle.
 
. . . . what mock1 said. That is industry std for 2.5" pipe -- "2-turn fabricated ell".
 
This is called "mitered joints" and it's a normal practise in SOME low pressure piping systems. My guess if you have to use double XX strong pipe you won't be allowed to make mitered joints! Have you thought about induction bends?
