Dimensions are in millimeters unless otherwise indicated. Wall thickness (t) must be specified by customer.

Dimensional Tolerances of Butt Weld Elbows - 45° and 90° - LR and 3D - ASME B16.9 -

Dimensional tolerances are in millimeters unless otherwise indicated and are equal ± except as noted.

Note:
MSS SP-43 only covers stainless steel buttweld fittings made for use with Schedule 5S and 10S pipe and Stub Ends suitable for use with Schedule 40S pipe, as defined in ASME B36.19. The dimensions and dimensional tolerances defined in MSS SP-43 are substantially the same as those in ASME B16.9 specifications from NPS 1/2 - NPS 24. Except with regard to the outside diameter at the bevel.
