ASME B16.5 is a key standard by the American Society of Mechanical Engineers.
It specifies dimensions, materials, pressure-temperature ratings, and tolerances
for pipe flanges (NPS 1/2 to NPS 24) and flanged fittings. Widely used in oil, gas,
chemical, and power industries globally, it ensures interchangeability and safety
of flanged connections, aiding consistent design and installation.
