Types of Super Duplex Flange (UNS S32750)
Weld Neck Flange
Welding Neck Flanges or Weldneck Flange (WN Flange) are easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a pipe or fitting. The long tapered hub provides an important reinforcement for use in several applications involving high pressure, sub-zero and / or elevated temperatures. The smooth transition from flange thickness to pipe or fitting wall thickness effected by the taper is extremely beneficial, under conditions of repeated bending, caused by line expansion or other variable forces.
UNS S32750 Slip On Flange (SO Flange)1. Slip On flange 2. Filled weld outside 3. Filled weld inside 4. Pipe
Socket Weld Flange (SW Flange)
Socket Weld flanges were initially developed for use on small-size high-pressure piping. Their static strength is equal to Slip On flanges, but their fatigue strength 50% greater than double-welded Slip On flanges. The connection with the pipe is done with 1 fillet weld, at the outside of the flange. But before welding, some space must be created between flange or fitting and pipe.
Super Duplex Steel Lap Joint Flange (LJ Flange)
1. Lap Joint flange 2. Stub End 3. Butt weld 4. Pipe or Fitting
Stainless Steel Threaded Flange are used for special circumstances with their main advantage being that they can be attached to the pipe without welding. Sometimes a seal weld is also used in conjunction with the threaded connection. Although still available in most sizes and pressure ratings, screwed fittings today are used almost exclusively in smaller pipe sizes. A threaded flange or fitting is not suitable for a pipe system with thin wall thickness, because cutting threads on a pipe is not possible.
Duplex UNS S32750 Blind Flange (BL Flange)
Flat Face Flange (FF Flange)
The Flat Face (FF) flange has a gasket surface in the same plane as the bolting circle face. Applications using flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting. These pipe flanges are used when the counter-flanges are flat faced. They are mainly used to connect to cast iron equipment, valves, and specialties. This flat face flange has a gasket surface in the same plane as the bolting circle face. Flat face flanges are never to be bolted to a raised face flange. ASME B31.1 says that when connecting flat face cast iron flanges to carbon steel flanges, the raised face on the carbon steel flange must be removed and that a full face gasket is required. This is to keep the thin, brittle cast iron flange from being sprung into the gap caused by the raised face of the carbon steel flange.
Super Duplex Steel Raised Face Flange (RF Flange)
Tongue And Groove Flange
Tongue And Groove Flange pipe flanges are more reliable type of flange joint but are costlier than the other type of flanges. The Tongue And Groove faces of these flanges must be matched. One flange face has a raised ring (Tongue) machined onto the flange face while the mating flange has a matching depression (Groove) machined into the face. Tongue And Groove facings are standardized in both large and small types. Tongue And Groove Flange differ from male-and-female in that the inside diameters of the tongue-and-groove do not extend into the flange base, thus retaining the gasket on its inner and outer diameter.
Super Duplex Ring Type Joint (RTJ) Flange
This is a pressure retaining plate with one solid end and one open end connected with a web or tie-bar. In normal operation, the open end forms the seal between two flanges and permits normal flow of fluid through pipe work. If the solid end is swung into position it effectively blanks of the pipe and halts the flow.

Slip On Flange (SO Flange)
The calculated strength from a Slip On flange (SO Flange) under internal pressure is of the order of two-thirds that of Welding Neck flanges, and their life under fatigue is about one-third that of the latter. The connection with the pipe is done with 2 fillet welds, as well at the outside of the flange. The X measure on the image, are approximately Wall thickness of pipe + 3 mm. This space is necessary, to do not damage the flange face, during the welding process.

1. Socket Weld flange 2. Filled weld 3. Pipe X = Expansion gap
Lap Joint Flange (LJ Flange)
Lap Joint Flanges have all the same common dimensions as any other flange named on this page however it does not have a raised face, they used in conjunction with a “Lap Joint Stub End”. These flanges are nearly identical to a Slip On flange with the exception of a radius at the intersection of the flange face and the bore to accommodate the flanged portion of the Stub End. Their pressure-holding ability is little, if any, better than that of Slip On flanges and the fatigue life of the assembly is only one tenth that of Welding Neck flanges.

1. Threaded flange 2. Thread 3. Pipe or Fitting
Blind Flange (BL Flange)
Blind Flanges are manufactured without a bore and used to blank off the ends of piping, Valves and pressure vessel openings. From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed flange types. However, most of these stresses are bending types near the center, and since there is no standard inside diameter, these flanges are suitable for higher pressure-temperature applications.
UNS S32750 Flat Face Flange (FF Flange)
Raised Face Flange (RF Flange)
These pipe flanges are the most commonly used flanges. The raised face thickness for 150# and 300# are included in the specified flange thickness and for higher rating, they are not included in the flange thickness. The Raised Face (RF) type is the most applied flange face and is easy to identify. It is referred to as a raised face because the gasket surfaces are raised above the bolting circle face.
F53 Tongue And Groove Flange
Ring Type Joint (RTJ) Flange
These pipe flanges are most reliable type of flange joint but are costlier than the other type of flanges. The Ring Type Joint flanges are generally used in high pressure (Class 600 and higher rating) and/or high temperature services above 800°F (427°C). A flange is a forged or cast ring of steel designed to connect sections of pipe or join pipe to a pressure Vessel, pump or any other integral flanges assembly.
UNS S32750 Spectacle Flanges
The function of an orifice flange is to provide access to a line for metering of gasses or liquids. An orifice plate is clamped between a pair of flanges when installed in a line and the whole assembly is refer to as an orifice flange union. Jack-screws within the assembly facilitate removal of the orifice plate. The orifice plate, the metering device, consists of a thin plate with a concentric, square edge, circular hole in the center. Two pressure tap-holes are drilled in each flange to measure pressure difference through the orifice.
UNS S32750 Long weld Neck Flange
Reducing Flanges are used in place of standard flanges to allow for a change in pipe size. The flange consists of one specified diameter with a smaller diameter bore size. Except for the bore and hub dimensions, a reducing flange has dimensions of the larger pipe size. Welding neck, slip-on, and threaded flanges can be reducers, and are considered an economical means to make a pipe size transition. Reducing Slip On Flange, Reducing Weld Neck Flange.
