Flanges are important mechanical connectors, mainly used to connect and seal pipeline systems, and are commonly used in key connection areas of equipment such as pipelines and valves.They include six categories: welding neck flanges, slip on flanges, socket flanges, threaded flanges,lap joint flanges, and blind flanges.ASTM A105 welding neck flanges are a widely used type of flange series, and are playing an increasingly important role in modern pipeline systems due to their excellent performance and wide range of applications.
Dimensions of ASTMA105 Welding Neck Flange
The dimensions of ASTM A105 welding neck flanges vary depending on the production standard.Common production standards for welding neck flanges include ASME B16.5, ASME B16.47, and EN1092-1.
ASEM B16.5 is a production standard for American, which includes flanges with sizes ranging from 1/2 inch to 24 inches and pressure ranges of CLASS 150, 300, 600, 900, 1500, and 2500.This Standard covers pressure-temperatureratings, materials, dimensions, tolerances, marking,testing, and methods of designating openings for pipeflanges and flanged fittings.
Dimensions of ASME B16.5 CLASS150 Flange
ASME B16.47 is the production standard for large-size flanges in the American standard, which includes welding neck flanges and blind flanges .The ASME B16.47 production standard is divided into A-series flanges and B-series flanges, This Standard covers pressure-temperature ratings ,materials , dimensions , tolerances , marking , and testingfor pipe flanges in sizes NPS 26 through NPS 60 .Includedare flanges with rating class 75 , 150 , 300400 , 600 , and 900.
Dimensions of ASME B16.47 A CLASS 150 Flange
EN1092-1 is the European standard for flange production.This European Standard for a single series of flanges specifies requirements for circular steel flanges inPN designations PN 2 , 5 to PN 400 and nominal sizes from DN 10 to DN 4000This European Standard specifies the flange types and their facings , dimensions , tolerances , threading ,bolt sizes , flange jointing face surface finish , marking , materials , pressure / temperature ratings andapproximate flange masses.The corresponding type of welding neck flange in EN1092-1 standard is TYPE11.
