How to find the thickness of pipe after bending 6

And, bottom line from that paper, was a decrease in wall thickness at the outside of the 90 bend from 18 mm (baseline) to 16 mm.

Generic issue for all pipes in all circumstances under all fluids and pressures and flowrates, will be, over time, how much additional material will be removed from the inside of the pipe at that point from erosion and corrosion? As the "original" 16 mm pipe wall becomes 14 mm, 12, 10 ... when will the fluid break through?
 
I would have thought that the real question is "is the bend as strong as the straight". If this is the case then we as a company would not accept any FEA analysis but require the supplier to hydro test three samples of each type of bend to supplied. If the bend fails before the straight then it is not acceptable.

Do you mean FEA Analysis to estimate deformations and Stress of the Pipe under loading conditions to check against allowable limit, or do you mean FEA to estimate the pipe thickness after bending ?

Refering to your comment "is the bend as strong as the straight". I would ask you as well what is typical L to D ratio of the pipe to consider it is the case?

Thanks
