[4] FLANGES

Specifications

SPECIFICATIONS:

ANSI B16.5 - Pipe Flanges and Flanged Fittings (American)

AS2129 - Flanges for Pipes, Valves and Fittings (Australian)

BS4504 - Circular Flanges for Pipe, Valves and Fittings (PN designated) - (now BS EN1092) (European)

AS4087 - Metallic Flanges for Waterworks Purposes (Australian)

BS10 - Specification for Flanges and bolting for Pipes, Valves and Fittings (British)

**AS2129 is a replica of BS10 but is stated in mm rather than inches. In some sizes bolt holes are slightly larger to give

better clearance

APPLICATION: Water Supply, Oil, Gas, Petrochemical, Irrigation, Fire Services, General Industry, Construction.

MARKING: All Flanges when possible will display a heat number, size, table, grade and dimensional standard

PLATE STEEL FLANGES: Plate flanges are mainly used for light duty, lower pressure or non-critical applications, commonly

referring to AS2129, BS10 or AS4087 standards. The manufacturing method involves cutting and machining from plate steel

FORGED STEEL FLANGES: Forged Steel flanges are commonly used and specified in the Oil, Gas, Petrochemical and

mining sectors, where pressure, temperature and safety considerations often specify the ANSI B16.5, ASME B16.47 or

BS4504 standards. The manufacturing method involves the hot forging of suitable steels prior to final machining

FLANGES [4]

“FLANGES ABOVE DN 600 ARE NOT INCLUDED IN ANSI B16.5 STANDARD AND THE CLASS DESIGNATIONS IN THESE

LARGE DIAMETERS DO NOT IMPLY SPECIFIC TEMPERATURE/PRESSURE RATINGS”

NOTE 1 — For each reduction of 0.01% below the specified carbon maximum (0.35%), an increase of 0.06% manganese

above the specified maximum (1.05%) will be permitted up to a maximum of 1.35%.

c Determined by either the 0.2% off-set method or the 0.5% extension-under-load method.
