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.
A pipe elbow, also known as an elbow fitting or simply an elbow, is a type of pipe fitting used to change the direction of a pipeline. It is designed to facilitate a smooth and gradual change in the flow direction of fluids or gases within a piping system.
Pipe elbows typically have a curved or bent shape, resembling the shape of a bent arm or elbow joint, hence the name. They are available in different angles, commonly 45 degrees, 90 degrees, and 180 degrees, although other angles may also be available depending on the specific application requirements.
