• ASME B16.9– which is standard for Factory-made Wrought Butt-welding Fittings for size NPS 1⁄₂ to NPS 48” and
• And B16.28– which is standard for Wrought Steel Butt-Welding Short Radius Elbows and Returns for size NPS 1⁄₂ to NPS 24”

Flanges

Here is the list of flange standard.

• List of materials that used to manufacture flanges is covered in ASME B16.5 & B16.47.
• ASME B16.5 is a standard for Pipe Flanges and Flanged Fittings that covers flanges sizes from NPS ½” to 24”
• Whereas ASME B16.47 is a standard for Large Diameter Steel Flanges that covers flanges sizes from NPS 26” to 60”
• ASME B16.1 is the standard for Cast iron pipes flanges & flanged fittings.
