As long as you comply with Table 300.5, which it looks like you are, I agree with Shaw0486 below

sch. 40 is fine as long as its not exposed to physical damage which its not because its in the ground.

Just be sure there is no other services in the ground. Plumbing, telephones service and corrugated drains, the last one I was on, we had to go deeper to miss all of them!
 
Thanks guys! this means a lot to me, if anyone else wants to chime in and agree or disagree join in.
I was sure but as soon as someone has a different point of view "I pay attention TO RISKY NOT TOO", I still thank my guy for pointing this out because sometimes I do provide the wrong material and sometimes Experienced Electricians will still install it DRIVE ME INSANE! But most of the time I'm a Nice Guy to THEM.... :):):):):):):):)
 
fyi. I am installing Concrete Pull Boxes with Drivable Lids Steel. 3'x4' ;) & am gonna use short 22's to stub in & out of the Pull Boxes ;)
 
Oh, Sorry 22deg bend. theres regular = short, and then longer 22deg bends like 36" radius or 48" radius. Thats also the case with the 45 & 90deg bends commonly known as sweeps for easier pulls.
So with my sch80 90deg 48" sweep at the end 30"s down with 24" ground cover am sticking out about 18" there wil sit my fusible disconnect. then I'll support the back with some steel & then I'll put yellow rigid pipe around to protect it.
 
Well when u start loosing profits due to overheads u save when u can otherwise you'll fail. IMO - try 2000' of sch 40 against 80!
 
Course if the project specs say Sch 80 then that's what you have to use. I'm sure that's not the case or you wouldn't have bid it for Sch 40 : )
