Description
A234 refers to pipe fittings of wrought carbon steel and alloy steel for use in moderate and elevated temperatures.
Typical applications include pressure piping and pressure vessel fabrication. The material consists of killed steel,
forgings, bars, plates, sheet, and seamless or fusion-welded tubular products with filler metal added.

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.
