For example a Class 150 A105 flange is rated to approximately 270 PSIG (1861 KPA) at ambient temperature, 180 PSIG (1241 KPA) at approximately 400ºF (204ºC) 150 PSIG (1034 KPA) at approximately 600ºF (315ºC), and 75 PSIG (517 KPA) at approximately 800ºF (426ºC). The charts show the dimensions of ASME B16.47 large size flanges class 150, 300, 400, 600, 900 (from 26 to 60 inches in diameter). Navy Flange Dimensions and size Charts . Wide flange beams are designated by the letter W followed by the nominal depth in inches and the weight in pounds per foot. Never say PSI as this can be confused with API 6B flanges which are rated by PSI (CWP). Refer to our Flange Chart – ‘Online Slide Rule’ above for flange dimensions. API ratings range from 2,000 to 20,000 psi (cold working pressure). in. Flange tables identify the type of flange you have.

Slip on Flange Dimensions – Class 150 to Class 1500 Slip on flange dimensions are covered in ASME B16.5 – which covers Pipe Flanges and Flanged Fittings for size NPS ½” to 24” for above NPS 26” to 60” it should be as per ASME B16.47. (Refer to pressure/temperature charts at this website for various material types). Flanges can withstand different pressures at different temperatures. PN16 G mm WN Blind SOW SW Nominal Size Class 300 Flanges to ASME B16.5 SOW, SW Threaded C mm Circle Diam. However there are a number of factors that can impact the pressure capability of a flange. The charts show the dimensions of ASME B16.47 large size flanges class 150, 300, 400, 600, 900 (from 26 to 60 inches in diameter). The number and diameter (mm) of the bolt holes for the example below of 300NB is: 12 x 25.4mm Class 150, 16 x 32mm Class 300, 16 x 34.9 Class 400, 20 x 34.9mm Class 600, 20 x 38.1mm Class 900, 16 x 54mm Class 1500 and 12 x 73mm Class 2500. as you are going to use bolt and stud to connect flanges.. However the actual dimensions and bore sizes have not changed. If two flanges have the same bore size (example 6 inches), the same material (example A105), but two different pressure ratings (one flange is class 150, the other 300), the lower rated flange (class 150) will be smaller, lighter, and less robust than the higher rated flange (class 300).
