Stainless Steel Flange is a ring of steel (forged, cut from plate, or rolled) designed to connect sections of pipe, or to join pipe to a pressure vessel, valve, pump or other integral flanged assembly.
Flanges are joined to each other by bolting, and are joined to the piping system by welding or threading (or loose when stub ends are used).
Types and applications of flanges
Slip-on flange is slipped over the pipe and then welded both inside and outside to provide sufficient strength and prevent leakage. Slip-on flanges are also used as loose back-up flanges when stub ends are used.
Blind flange is a flange without a centre bore, used to shut off a piping system or vessel opening.
Weld neck flanges are designed to be joined to a piping system by butt welding.
They are relatively expensive due to the weld neck, but are preferred for high-stress applications.
Lap joint flange is again similar to a slip-on flange, but has a radius at the intersection of the centre bore and the flange face to accommodate a lap stub end.
Pressure Ratings
Classes 150, 300, 600, 900, 1500 and 2500.
Manufacturing specification
AS2129, ASTM A182M and ASME B16.5.
Plate stainless steel flanges are forged or cut and machined from plate.
Waterworks flanges to AS4087 are also available subject to enquiry.
