British standard BS10 specification for flange and bolting for pipe, valves, and fittings. This covers plain, boss, integrally cast or forged, and welding neck type flanges, in ten tables. Although BS 10 is obsolescent, it remains in use for the dimensions of light duty, economy stainless steel flanges in applications where corrosion resistance and/or hygiene, rather than high pressures and temperatures, are the primary considerations. The following tables details the applicable standard dimensions from tables D,E,F and H of BS10. Surface treatment of flange: the yellow painting flange flange is bright and dazzling, it is needed in the markets of south east of Asia and Africa; black painting flange looks more seriously than other colors, it is needed in the markets of south east and mild east of asia; anti rust oil flange is most markets of the world, and it is the cheapest treatment method.
