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.

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.

Buttweld Fitting Weights

ASME buttweld fitting specifications do not specify weights for fittings. Weights quoted in the table on this page are based on manufacturers information and should be considered as approximate and provided as a guide only (fitting weights can vary considerably between manufacturers due to differences in construction). Weights in these tables are taken from Hackney Ladish, Inc. Hackney Ladish, Inc. is one of the largest and most versatile fitting producers in the world. Hackney Ladish, Inc. is headquartered in Dallas, TX and operates 2 facilities containing 380,000 square feet of manufacturing.
