1 - Hyupshin Flanges8-71 ABS 10 : 1962 british Standard bs 10 : 1962 - Specification for Flanges and Bolting for Pipes, Valves,and Fittings. This covers plain, boss, integrally cast or forged, and welding neck typeflanges, in ten tables. Although bs 10 is obsolescent, it remains in use for the dimensionsof light duty, economy stainless steel flanges in applications where corrosion resistanceand/or hygiene, rather than high pressures and temperatures, are the primaryconsiderations. The following tables detail the applicable standard dimensions fromTables D, E, F and H of BS Dimensions Based on Tables D and E of bs 10 : 1962 Note-Bolt hole diameters are as follows: For 1/2 in and 5/8in bolts, the bolt hole shall be 1/16 in larger than the bolt diameter.

2 For 3/4in bolts and larger, the bolt hole shall be not more than 1/8in larger than the bolt 10 Table D DimensionsBS 10 Table E DimensionsFlange SizeDesignation(Nominal Bore of Pipe)Overall Diameterof Flange Flange ThicknessBolt Circle DiameterNumberofBoltsDiameterofBoltsOver all Diameterof Flange Flange ThicknessBolt Circle DiameterNumberofBoltsDiameterofBoltsinin ininininininin1/233/43/1625/841/233/41/4 25/841/23/443/1627/841/241/427/841/2141/ 23/1631/441/241/29/3231/441/211/443/41/4 37/1641/243/45/1637/1641/211/251/41/437/ 841/251/411/3237/841/2265/1641/245/863/8 41/245/821/261/25/16545/861/213/32545/83 71/43/853/445/871/47/1653/445/831/283/86 1/245/8815/3261/285/8481/23/8745/881/21/ 2785/85101/281/485/8109/1681/485/86111/2 91/485/81111/1691/483/47121/2101/485/812 3/4101/483/48131/41/2111/285/8131/43/411 1/283/49141/25/8123/485/8141/213/16123/4 123/410165/81483/4167/814123/412183/4161 23/418116127/813191/43/4171/4123/4191/41 171/4127/814203/47/8181/2127/8203/411/81 81/2127/815213/47/8191/2127/8213/411/419 1/2127/816223/47/8201/2127/8223/411/4201 /2127/817241213/4127/82413/8213/4127/818 251/4123127/8251/413/823167/819261/21241 27/8261/211/224167/820273/411/8251/4167/ 8273/411/2251/4167/8212911/8261/2167/829 15/8261/2161223011/8271/21613013/4271/21 61233111/8281/21613113/4281/216124321/21 1/4293/4161321/217/8293/41611 - Hyupshin FlangesABS 10 : 1962 Flange Dimensions Based on Tables F and H of bs 10 : 1962 Note-Bolt hole diameters are as follows: For 1/2 in and 5/8in bolts, the bolt hole shall be 1/16 in larger than the bolt diameter.
