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). Flange Table Nominal Size 80mm (3 in) Height of raised face Thickness of flange Diameter of flange Bolt circle number Number of bolts. Size D B PCD No. 4331.2 – Cast Iron Flanges (ISO 7005-2) PN2.5 / 6 / 10 / 19 / 20 / 25 / 40 / 50 EN1092-2 specifies a thinner flange thickness for Ductile Iron in larger sizes which is shown in the Ductile Iron column. In general, this temperature is the same as that of the media in line and the external environment, whichever is greatest (but also lowest temperature of each must be factored for low temperature service). AS4331 has adopted ANSI drilling and sizes but uses PN rating classes. AS4331 is a reproduction of ISO 7005 which is based on the American and European flange systems PN20, PN50, PN 110, PN 150, PN 260 and PN 420 steel flanges are “designed to be interchangeable” with flanges to American standards ANSI/ASME B16.5 and MSS SP44; they are not identical but are “deemed to comply” with dimensions specified in ANSI/ASME B16.5 and MSS SP44 as appropriate. The below two tables are examples of two material groups according to ASTM, flange pressure-temperature ratings to ASME B16.5 – 2009. Class 900: PN150 Equivalent imperial sizing is rounded to the nearest multiple of 25mm (for 2” and over) as below. Thus W12 × 19 designates a wide flange beam with a depth of 12 inches and a nominal weight of 19 pounds per foot. EN 1092-1 is for steel flanges, EN 1092-2 is for iron flanges, EN 1092-3 is for alloy flanges, EN 1092-4 is for aluminium alloy flanges. Forged steel flanges, ASME B16.5, are made in seven primary ratings: A Class 300 flange is rated to a higher pressure than a Class 150 flange, because a Class 300 flange is constructed with more metal and therefore can withstand more pressure. Flange Diameter Bolt Circle Diameter Bolt Holes x Hole Diameter Flange Diameter Bolt Circle Diameter Bolt Holes x Hole Diameter Flange … AS2129 originates from BS10 and has been metricated. For intermediate temperatures, linear interpolation is calculated by manufacturers. ANSI was originally born from API, consequently in class 600 to 900 and 1500 ANSI the flanges are dimensionally equivalent to API 2,000, 3,000 and 5,000 in most sizes to ANSI 300NB (12”) API 13 5/8” but ANSI flanges being manufactured from lower yield strength carbon steel are rated to lower working pressure. However in general industrial, commercial and waste/water industries AS2129 Table flanging is the most common. in. Wide flange beams are designated by the letter W followed by the nominal depth in inches and the weight in pounds per foot. EN 1092 evolved from DIN 2501 which became part of ISO 7005, then EN 1092 was created as the standard for DIN based flanges. In some cases slightly larger bolt holes provide better clearance as metric bolts are specified in lieu of UNC bolts used by BS10.
