Ally International Co is renowed BS 4504 Flange Manufacturers in India, British Standard BS 4504 material standard Specification for Flanges and Bolting for Pipes, Valves, and Fittings. This covers plain, boss, integrally cast or forged, and welding neck type flanges, in ten tables. Although BS 4504 is obsolescent, it remains in use for the dimensions of light duty, economy stainless steel flanges in applications where corrosion resistance and hygiene, rather than high pressures and temperatures, are the primary considerations. BS 4504 tables below detail the applicable standard dimensions from PN6, PN10, PN25 and PN40.
