Equipment for measuring and testing the orthogonality of tube ends, comprises a rigid sleeve with a calibrated slot and an internal diameter which allows it to be slid over the tube end without play

摘要

A rigid sleeve (1) has a length (L) and an internal diameter which is just sufficient to allow it to be slid without play over the end of a tube (T) with external diameter (De). One side of the sleeve has a longitudinal slot (2) with graduations (G1-G7). When the rim of the sleeve (R1) is aligned with a tube edge (K1) any lack of orthogonality is measured by the registration of the opposite tube edge (K2) with the graduations
