General notes:
- Dimensions are in millimeters unless otherwise indicated.
- Wall thickness (t) must be specified by customer.
- The shape shall be ellipsoidal and shall conform to the requirements given in the ASME Boiler and Pressure Vessel Code.
- Length H applies for thickness not exceeding that given in column "Wall Thickness" for Length, H.
- Length H1 applies for thickness greater than that given in column "Wall Thickness" for NPS 24 and smaller. For NPS 26 and larger, length H1 shall be by agreement between the manufacturerand purchaser.
DIMENSIONAL TOLERANCES OF END CAPS ACCORDING TO 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 B36.19M. 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 up to NPS 24. Except with regard to the outside diameter at the bevel.
