Mitre bends have a number of problems.
--The sharp bends at the cuts produce very high stress, and they're

     subject to fatigue.
--Fabrication is tricky because of the need for precision and distortion at the welds
--You need full penetration welds that should be welded and ground both sides
--The weld joints also require some level of NDT which adds to the cost --Fluid flow through a miter is turbulent so the pressure drop will be higher and

    there may be problems with corrosion depending on the material chosen.
