This Standard covers minimum requirements for Classes 150 and 300 cast ductile iron pipe flanges and flanged fittings. The requirements covered are as follows: (a) pressure-temperature ratings (b) sizes and method of designating openings of reducing fittings (c) marking (d) material (e) dimensions and tolerances (f) bolts, nuts, and gaskets (g) tests.<\/p>\n
