Hello members
I would like to have clarification with regards to shaft alignment tolerances mentioned in API 686 second edition dec 2009 clause 5.4.6.2 which states"When using reverse rim ( dial) indicator methods or laser equipment that resolves alignment into reverse rim equivalent readings, the max out of tolerance is 0.5 mm per meter ( 0.5 mils per in)at both flex plane locations.
Kindly clarify if the inch mentioned in tolerance ( 0.5 mils per inch) denotes the separation between flexing planes (spacer length) or the shaft diameter or the coupling dia?
Shall be thankful for your responses
