Dimensional Standard for Butt-Weld Fittings:

The dimensional standard for butt-weld fittings is ASME B16.9, which covers the dimensions, tolerances, and markings for wrought butt-welding fittings like elbows, tees, reducers, and caps. This standard ensures compatibility and consistency in fitting dimensions across various piping systems.
