Given the prevalence of piping standards in industrial design, the similarity between "B1864" and the well-known of standards is a likely source of confusion. The ASME B16 Series is a collection of over 30 different standards that define the dimensions, pressure-temperature ratings, and materials for pipe flanges and fittings.
The standard provides detailed geometric charts for an array of head configurations to suit distinct aesthetic and structural needs: ASME standards are copyrighted and distributed through ASME
