Flanges and their joints. Circular flanges for pipes, valves, fittings and accessories, PN designated - Cast iron flanges Ingestion-build-224916 A second furnace thermocouple has1 Scope This standard specifies requirements for circular flanges made from ductile, grey and malleable cast iron for DN 10 to DN 4000 and PN 2,5 to PN 63. (See 4. 1 and 4. 2). This standard specifies the types of flanges and their facings, dimensions and tolerances, bolt sizes, surface finish of jointing faces, marking, testing, quality assurance and materials together with associated pressure temperature (p T) ratings.
