Industrial Flange Standards Reference Guide - International Specifications
Browse Caman Engineering's comprehensive catalog of industrial flange standards from American, British, Australian, and Japanese specifications. Our reference guide helps engineers and procurement specialists identify the exact flange specifications needed for petrochemical, mining, and industrial applications. All flanges are manufactured to meet or exceed international standards including ASME, BS, AS, and JIS specifications.
American (ASME) Flange Standards
American Society of Mechanical Engineers (ASME) standards are widely used globally for industrial flanges. These specifications include pressure ratings from 150 to 2500, covering applications from low-pressure systems to high-pressure industrial processes.
| Country of Origin | Standard | Subject |
|---|---|---|
| American | ASME B16.5 | Flanges ASME 150/300 |
| American | ASME B16.5 | Flanges ASME 600/900 |
| American | ASME B16.5 | Flanges ASME 1500/2500 |
| American | ASA / MSS | Lap Joint Stub End |
| American | ASME B16.5 | Ring Groove Dimensions |
| American | ASME B16.5 | Socket Weld Flanges |
| American | ASME B16.36 | Orifice Flanges |
| American | ASME B16.47 Series A | Large Flanges |
| American | ASME B16.47 Series B | Large Flanges |
British (BS) Flange Standards
British Standards (BS) and European Norm (EN) flange specifications are commonly used throughout Europe and in many Commonwealth countries. These standards include both imperial and metric dimensions to accommodate various industrial requirements.
| Country of Origin | Standard | Subject |
|---|---|---|
| British | BS3293 | Large Flanges |
| British | BS EN 1092 | Metric Flanges DN 6/10 |

| British | BS EN 1092 | Metric Flanges DN 63/100 |
Australian (AS) Flange Standards
Australian Standards (AS) are specifically designed for the unique requirements of Australian industrial applications. These standards include table classifications from D through T, covering a wide range of pressure ratings and applications.
| Country of Origin | Standard | Subject |
|---|---|---|
| Australian | AS4087 | Flanges |
| Australian | AS2129 | Flanges Table D/E |
| Australian | AS2129 | Flanges Table F/H |
| Australian | AS2129 | Flanges Table J/K |
| Australian | AS2129 | Flanges Table R/S/T |
Japanese (JIS) Flange Standards
Japanese Industrial Standards (JIS) provide specifications for flanges commonly used in Asian markets. These standards use kilogram ratings (5kg, 10kg, 16kg) to indicate pressure classes.
| Country of Origin | Standard | Subject |
|---|---|---|
| Japanese | JIS B2220 | Flanges Rating 5 Kg |
| Japanese | JIS B2220 | Flanges Rating 10 Kg/16 Kg |
