What Is A Reducing Flange?
Reducing Flanges dimensions vary according to the two pipe sizes they have to connect. Stainless Steel Reducing Flange is a standard of reducing flanges. ANSI B16.5 Reducing Flanges have one end in one diameter and the other in another diameter. ANSI B16.5 Class 150 reducing threaded flange connect two low pressure class pipes. ASME B16.5 Reducing Flanges can range from NPS1/2 to NPS24 standards. ASTM A182 SS reducing wn flange has a welded neck for extra strength. ASME B16.47 Series A and B Reducing Flanges have larger bore diameters ranging from 26 inches to 60 inches.

Stainless Steel Reducing Flange Use In Nuclear Power Generation Plants?
Reducing Weld Neck Flange don’t have threads, instead, they allow the pipe to slip through them for fixture. Inconel reducing pipe Flanges are made up of nickel alloy and they can come in different classes such as the Reducing Slip On Flange. The usage of stainless steel reducing flange is needed in applications where two pipes of different diameters have to be connected together. Specialty flanges for specific conditions can have different material composition. For example, the Threaded Reducing Flange can be used in acid flow lines as the copper alloy is resistant to acidic corrosions. Different alloys such as Reducing Flange Adapter could also be used. The applications are broad such as food processing industries, chemical industries, nuclear power generation plants, water desalination plants, pollution control systems and many others.

3 Inch, SCH40, ASME B16.5, Reducing Slip On Flange
8 Inch, 150 LB, Schedule 180, Reducing Socket Weld Flanges
ASME SA182 UNS S32550, Raised Face Reducing Flanges
The number one feature of Reducing Slip On Flanges, is that they are a highly economical way to make transitions between pipes of different sizes. ASME B16.5 Reducing Flanges can be fabricated using a reducing spool with concentric or eccentric reducer & desired flange at each end OR it could be a single flange with internal reduced bore to connect different sized and shape fittings on either sides.
Cast Iron Reducing Flanges are fillet welded with a socket. Carbon Steel Reducing Flanges is made up of carbon steel whereas the 4x3 Reducing Flanges is made up of a different alloy. The composition does not affect the Reducing Flanges Dimensions but it can affect the pressure containment level, strength and corrosion resistance of a flange. Class 300 reducing Flanges threaded belong to the pressure class 300 and also have threads through which they can be attached to the pipes.
