If on the other hand you could either decline/return as XL83NL suggests or use in lieu of Sch 40 if it suits schedule and no flow concerns with smaller ID.
RE: Pipe thickness
Unfortunately you have a major problem and nobody can assist you with it.
If it was the other way around you may have been able to get away with it as noted above but basically you have to return the pipe and reorder the correct pipe.

RE: Pipe thickness
1. reduce corrosion allowance. Is the specified allowance really required? Do you have a long history in this service with little corrosion.
2. Reduce manufactures tolerance. Measure the S40 pipe. I bet it is well within the 12.5% allowance.
3. review the how the design pressure was calculated. Is this conservative?
RE: Pipe thickness
Elaborating on KevinNZ's point 3 - was schedule 80 calculated based on pressure only or did the calculation take into account structural requirements i.e. deflections and thermal loading etc. ?
