1. BRITISH STANDARDS : In many instances, it is possible to find a British Standard which may be substitutes for American Standards. For example, BS 2080 (British Standard for Face to Face or End to End dimensions of valves) is identical to ANSI/ASME B16.10. Similarly BS 3799 and ANSI/ASME B 16.11 also compare.There are certain British Standards referred by Indian Manufacturers for Piping and Valves. The most commonly referred British Standards in the Piping Industry are : BS 10 : Flanges BS 806 : Pipes and Fittings for Boilers BS 916 : Black Bolts, Nuts and Screws BS 970 : Steel for Forging, Bars, Rods, valve steel, etc. BS 1212 : Specification for Float Operated Valves BS 1306 : Copper and Copper alloy pressure piping system BS 1414 : Gate Valves for Petroleum Industry BS 1560 : Steel Pipe Flanges BS 1600 : Dimensions of Steel Pipes BS 1640 : Butt Welding Fittings BS 1740 : Wrought Steel screwed pipe fittings BS 1868 : Steel Check Valves for Petroleum Industry BS 1873 : Steel Globe and Check Valves for Petroleum Industry BS 1965 : Butt welding pipe fittings BS 2080 : Face to Face / End to End dimensions of Valves BS 2598 : Glass Pipelines and Fittings BS 3059 : Boiler and Super-heater Tubes BS 3063 : Dimensions of Gaskets for Pipe Flanges BS 3381 : Metallic Spiral Wound Gaskets BS 3600 : Dimensions of Welded and Seamless Pipes and Tubes BS 3601 : C.S.
