Dimensional Standard for Threaded & Socket Weld Pressure Fittings:

The dimensional standards for threaded and socket weld pressure fittings are ASME B16.11 and MSS SP83. These standards cover the dimensions, tolerances, and markings for threaded and socket weld fittings such as elbows, tees, couplings, and unions. They ensure compatibility, reliability, and consistency in high-pressure piping systems.
